Biomimetics at Mawashi
In 1997 Mawashi began studying and applying
“biomimetics” to improve protection and performance
for our technologies & systems, which are used in
dangerous environments. Mawashi specializes in
research, development, design, technology transfer,
prototyping, and manufacturing.

For Mawashi, biomimetics involves studying
the fundamental elements and actions of our planet
and the life forms that inhabit it and then applying
(“mimicking”) specific key aspects in order to solve
protection and performance related problems. We find
areas and aspects in nature with countless years of
“design-optimization” that can be transferred and
applied to help create innovative solutions for current
and future challenges.

The study of biomimetics comprises
extensive examining and understanding of naturally
occurring things and events on the macro-scale and
micro-scale. The application of biomimetics comprises
detailed analysis and synthesis to translate/transfer the
obtained knowledge into useable and beneficial forms
(i.e. knowledge, processes, technologies, systems,
etc.) for the intended applications.

Previous biomimetics investigations by
Mawashi include:
Muscles, Bones, and Impact for the Human Body
Horns, Skulls, and Impact for Horned Animals
Lightning, Earthquakes, and Tsunamis
Sound Wave Reception for Dolphins and Whales
Sound Wave Reception for Humans and Animals
Evaporative-Cooling for the Human Body
Thermoregulation for Fur-Bearing Mammals
Exoskeletons of Arthropods
Mobility and Flexibility of the Human Body
Balance and Load-Carriage for Humans and Animals

At Mawashi, we feel that biomimetics is a
key component to providing exceptional and novel
solutions for many of the difficulties associated with
survivability and functionality. Every one of our
projects includes the study and application of
biomimetics; and due to this fact we have had many
noteworthy successes with apparel, equipment,
technologies, and systems that improve protection and
performance for individuals.

Biomimetics and Core Competencies
Biomimetics is a core competency of
Mawashi and it is consistently utilized to enhance
products and systems. Additionally and very
importantly, we employ biomimetics to continually
expand our core competencies and solutions-provider
capabilities in the science & technology areas of:
Incident Energy Management
Heat Stress Management
High-Mobility Exoskeleton Systems
Human Factors & Ergonomics

Furthermore, we employ biomimetics to a
select degree to heighten our capabilities and
competencies in the other key science & technology
areas of:
Needs/User Driven Development
Apparel & Equipment Design
Systems Integration
Advanced Materials

Through expanded abilities in these areas we
are better positioned to provide novel and effective
solutions for improved protection and enhanced
human performance.

In subsequent sections, a summary of how
biomimetics has improved our capabilities and
competencies in the areas of Incident Energy
Management, Heat Stress Management, High-Mobility
Exoskeleton Systems, and Human Factors &
Ergonomics is provided as well as how biomimetics
and these abilities have facilitated improved products
and systems for the end user.

Incident Energy Management
We define incident energy management as
technologies and systems that serve to redirect,
absorb, and/or impede energy that is incident (i.e.
coming in contact) with individuals, vehicles, and/or
equipment. In this context, incident energy can be
from single/multiple blunt-impact, ballistic, blast
and/or other detrimental events.

By identifying macro and micro level
mechanisms in nature that have optimal “methods” of
managing energy that is incident on a specific entity,
object, or surface we are able to observe and then
“borrow” from these “methods”. Mechanisms and
aspects of primary interest involve incident energy that
is encountering another medium and the ways that
energy flows and is redirected, reflected, impeded, and
absorbed by the various elements of a given material,
configuration, shape, element, etc. The application of
this knowledge supports the creation of new
technologies and systems for very effective incident
energy management.

Two interesting examples of achievements
realized, with our approach to biomimetics
enhancements of incident energy management, involve
the reduction of ballistic back face signature (decrease
of 65–80% at relatively equivalent weights and
significantly less cost compared with many current
offerings for composite armor insert panels) and
reduction of blunt-force impact (decrease of up to
150% compared to competitive products). The
biomimetics influenced/enhanced surfaces, shapes,
ratios, relations, configurations, etc. that we identified
and implemented had a very positive affect on
improving protection against ballistic and blunt-impact
threats, while maintaining lightweight designs and
reasonable product costs.

In terms of Mawashi products, we have
implemented biomimetics enhancements in the
following: Blunt-Impact Protection Suits;
Blunt-Impact Chest Protectors; Ballistic Protection
Body Panels; Ultra-Lightweight Stab Resistant Body
Plates; Multi-Threat Protection Body Plates; Concept
for Novel Blast Mitigation & Protection for Vehicles &
Personnel; and Durability & Reliability Enhancement
Covers for Ceramic Armor.

Five major investigations of biomimetics and
incident energy management have been successfully
completed and these have resulted in a greatly
expanded knowledge base for incident energy
management as well as assisted in creating highly
advanced protective apparel and equipment. These
incident energy biomimetics studies include the

Incident Energy Management
Muscles, Bones, and Impact for
the Human Body

The human muscular and skeletal systems
have an inherent and efficient ability to manage
incident energy. Consider the cases of running or
jumping where the body is able to withstand and
manage repeated impacts of relatively appreciable
intensity. The body is also quite able to withstand
blunt-impacts, up to a certain level of intensity. Our
biomimetics study in this area taught us that the
shapes, compositions, ratios/relations, configurations,
interactions, and reactions of the different parts of the
muscular and skeletal systems play a major role in how
effectively the body manages incident energy. We
adopted key aspects from the muscles and bones and
applied these in our protective technologies and
systems for blunt-impact protection. The information
acquired also serves to provide excellent guidance for
future technologies and systems that offer protection
against ballistic and blast threats.

Horns, Skulls, and Impact for
Horned Animals

Our study of the antilocapridae and bovidae
families of animals (which include pronghorn
antelope, bison, and rams – known as “true” horned
animals) focused on the incident energy management
aspects of the horns and skulls. Particular attention
was paid to the energy redirection and absorption
mechanisms and the manners for safeguarding of the
brain, which is in close proximity to the areas
routinely impacted at high-intensities. We observed
the manner in which the configurations, compositions,
shapes, multi-layer constructions, and other factors for
the horns and skulls contributed to highly effective
incident energy management. From this study we
created advanced lightweight protection technologies
and systems for stab, ballistic, blunt-impact, and
multi-threat events as well as gained excellent
information and insights for future helmet

Incident Energy Management
Lightning, Earthquakes, and Tsunamis

The high intensity of energy and high rate of
flow, redirection, absorption, and impedance during
the dramatic events of a lightning storm, earthquake,
and tsunami provide a very diverse and informative
area of study on incident energy management. In
particular, the energy-wave propagation modes
through different media and the phenomenal energy
transfers that take place were areas of focus for us.
From this study, we greatly increased our knowledge
of incident energy management for blast and ballistic
resistance in protective systems.

Sound Wave Reception for
Dolphins and Whales

The study of how dolphins and whales
receive/sense sound energy waves is very interesting
with respect to incident energy management. The
finely tuned and optimized shapes, configurations,
compositions, and interactions of the ear and skull
structures (which facilitate very precise energy
transfer) provide a wealth of knowledge in terms of
energy redirection, absorption, and conversion
mechanisms. From our biomimetics study in this area,
we arrived at enhanced knowledge on blunt-impact,
ballistic, and blast resistance which is directly
applicable to protective technologies and systems.

Sound Wave Reception for
Humans and Animals

We investigated the human ear and the ears
of several other mammals (e.g. bats, dogs, cats,
elephants, etc.) and found additional mechanisms for
precise energy transfer. The compositions,
configurations, shapes, and relations of the elements of
an ear are crucial to the incident energy management
(i.e. energy redirection, absorption, and conversion)
that occurs. From this study, we further advanced our
knowledge of and expertise in blunt-impact, ballistic,
and blast resistance for protective technologies.

Heat Stress Management
In terms of heat stress management we refer
to the evacuation of body heat, that is withdrawn via
technologies and systems, at levels sufficient enough to
significantly reduce the likelihood of heat stress and
increase comfort for individuals thereby increasing
performance in difficult and dangerous environments.

Through studying and applying highly
effective systems in nature (i.e. in humans and animals)
we are able to make appreciable advances in cooling
technology for individuals. By applying these natural
cooling mechanisms within our designs we achieve
optimization of thermoregulation/cooling within and
underneath complex apparel and equipment.
Furthermore, through our studies we arrived at the
optimal and most safe manner in which to cool the
human body under extreme conditions and while
wearing heavy and/or insulating protective systems; as
well reached the conclusion that enhanced evaporative
cooling is an ideal process for use in/under protective
apparel and equipment.

Examples of performance benefits attained
with our biomimetic enhancement of heat-stress
reduction include: lower system cost in relation to
comparable products/systems; simple low-tech
solution with inherently better reliability; ability to
provide cooling/comfort in hot environments;
avoidance of thermal shock to individuals due to safe
natural/biological cooling processes; and adjustability
to meet variable heat loads.

The Mawashi product, a Thermoregulation
and Cooling System for Torso, is an excellent example
of the biomimetics enhancements that are possible for
individual cooling. Two major investigations into
cooling/thermoregulation and biomimetics
enhancements were conducted and these are
summarized as follows.

Heat Stress Management
Evaporative-Cooling for the Human Body

Through observing the human body’s
evaporative-cooling mechanisms for managing heat we
have gained the necessary knowledge to create apparel
and equipment that augment the natural “cooling”
methods of the body. By working with the body’s
natural processes for perspiration, Mawashi is very
effective at regulating temperature. Perspiration is an
evaporative-cooling process where sweat (in liquid
form) is emitted by the skin and then heat from the
body drives the evaporation (change in state from
liquid to vapour) of sweat; and thus body heat is
absorbed and expelled through the evaporation of

Our systems supplement this natural process
by withdrawing heated and moisture-saturated air
away from the body (and out from underneath apparel
and equipment). In this way, we accelerate and
increase the evaporative-cooling process by pushing
hot humid air out/away and drawing in relatively less
warm and less humid air to take up the emitted heat
and moisture. This system also serves to improve
comfort for the individual since they are continually
being refreshed with the circulation of relatively cooler
and drier air underneath their protective apparel and

With our approach, we work with the body
to “amplify” its inherent ability to regulate temperature
and protect from heat stress while providing advanced
cooling (thermoregulation) and comfort systems for
Thermoregulation for Fur-Bearing

We have studied the cooling mechanisms that
exist within the animal kingdom (specifically
mammals such as horses, antelopes, and camels). The
natural systems of these animals integrate many
complex factors and provide highly effective heat
stress management (i.e. an evaporative cooling system
that is utilized in conjunction with a thermally
insulating outer layer of fur). This study identified
parallels with many types of protective apparel and
equipment where the blunt-impact, ballistic, and blast
resistant systems cover regions of the human body and
these systems inherently act as a thermal insulator to
keep body heat in.

By understanding how fur-bearing mammals
utilize evaporative-cooling that is in conjunction with
an insulating layer we gained crucial insights into the
design of individual cooling systems that integrate into
and readily work in combination with body armor and
associated protective products and systems.

High-Mobility Exoskeleton Systems
Within our current focus, high-mobility
exoskeleton systems refer to apparel and equipment
that offer increased levels of protection and
performance while maintaining or enhancing mobility,
ergonomics, flexibility, and comfort for individuals.

By understanding and transferring what we
have learned from nature about integrated
exoskeletons, hard shell components, and complex
multi-directional joint-regions we are able to provide
high-mobility articulated rigid or semi-rigid
protection systems (i.e. exoskeleton-type armor for
ballistic, blast, and blunt-impact resistance) while
maintaining full protection levels, coverage areas,
range of motion, ease of motion, ergonomics,
comfort, and function for individuals. Specific
examples of the novel properties and performance
gains achieved with our biomimetics exoskeletons
approach include: unrestricted range and ease of
motion for joint regions; reduced fatigue and increased
comfort for end user due to unimpeded motion; and
protective coverage over complex joint regions.

Mawashi products that have benefited from
this approach include: Blunt-Impact Protection Suits;
Blunt-Impact Chest Protectors; Ballistic Protection
Body Panels; Ultra-Lightweight Stab Resistant Body
Plates; and Multi-Threat Protection Body Plates.

Our biomimetics and exoskeletons study is
summarized below.

Exoskeletons of Arthropods

This study involved investigating arthropods
(i.e. insects, arachnids, and crustaceans such as
beetles, ants, bees, dragonflies, grasshoppers,
scorpions, spiders, lobsters, crabs, etc.) that have a
hard exterior surface or shell, which makes up the
skeletal system and offers protection from the
environments in which they live. This is a unique area
in nature since these creatures have bodies that are
nearly completely encased in rigid materials but they
are still highly mobile due to the sectioned
components and joints regions of the exoskeleton.

Nature has optimized on a macro and micro
level the shapes, compositions, configurations,
relations, and proportions of the exterior hard shell
components and the interconnections, integrations,
and joint-regions between them to provide full
mobility and flexibility while maintaining the
necessary structure, protection, and function. Our
study has facilitated direct applications of “optimized
designs” that have resulted in greatly improved
ergonomics for protective systems.

Human Factors & Ergonomics
Human factors and ergonomics is a continual
area of focus for Mawashi since we are always striving
to create apparel and equipment that is more
functional, comfortable, and ergonomic while
delivering the necessary protection and performance.
From the biomimetic studies we carried out on human
mobility and flexibility and on balance and
load-carriage for humans and animals we created
guidelines and principles for human factors centered
designs that in turn have supported the creation of
extremely ergonomic protective technologies and

Several examples of the novel features,
ergonomic benefits, and performance increases
attained with our approach to biomimetics
enhancements of human factors include: body armor
that works in conjunction with the body’s natural
movement; dramatic reduction of restriction and
fatigue from protective systems; successful integration
of armor coverage with complete ease and range of
motion for joint regions; and optimized armor
coverage, fit, comfort, and stability over all body
Specific Mawashi products that were
developed with our biomimetics and human factors
approach include: Blunt-Impact Protection Suits;
Blunt-Impact Chest Protectors; Ballistic Protection
Body Panels; Ultra-Lightweight Stab Resistant Body
Plates; Multi-Threat Protection Body Plates; and
Thermoregulation/Cooling System for Torso. Our
biomimetics studies focused on human factors and
ergonomics are described hereafter.

Mobility and Flexibility of the
Human Body

We conducted numerous and extensive
investigations into how the human body naturally
moves, bends, twists, etc. and we gained insights into
the how the structures and interactions of the joints,
muscles, bones, tendons, etc. of the human body
directly affect mobility and flexibility. This study has
been extremely important and instrumental to
Mawashi’s ability to design/develop protective apparel
and equipment that is very “user-friendly” and ensures
that full comfort, function, fit, movement, etc. has
been accounted for and properly incorporated within
the final products and systems.

Balance and Load-Carriage for
Humans and Animals

We have also studied the mechanisms utilized
by humans and animals to balance themselves while
moving or stationary and the means (i.e. centers of
gravity, load distribution patterns, physiological
aspects, etc.) by which load/weight, from the body
and/or external items, is distributed throughout the
body and to the ground. The aspects of balance and
load-carriage are too often neglected during the
design/development of protective apparel and
equipment and this can result in systems that may
actually hinder the performance of end users.
