Gyro sensor

A gyro sensor is a measurement
device. Its uses include calculating angle and
rotation speed and controlling position. The
term "gyro" refers to a "ring" or "rotation“

OLED


An
organic light emitting diode

(
OLED
) is a
light
-
emitting diode

(LED) in which the
emissive

electroluminescent

layer is a film of
organic
compounds

which emit light in response to an
electric current. This layer of
organic semiconductor

material is situated between two electrodes

Silicon Microphone
-

are more compact than
traditional microphone systems because they
capture sound and convert it to a digital signal on the
same chip.


Carbon Nanotubes
-

(also known as
buckytubes
) are
allotropes of carbon

with a cylindrical nanostructure.
Nanotubes have been constructed with length
-
to

diameter ratio of up to 132,000,000:1,
[1]

which is
significantly larger than any other material.

WHY NANOTECHNOLOGY?


Cell phones, ipads, and ipods play such an
integral part of our lives.


How did we ever communicate, entertain, or
even survive without them?


Today’s consumer electronics are modern
conveniences, but their technological roots
are ancient



TECHNOLOGICAL ADVANCES TIMELINE


1826


First photographic image taken with a
camera


1951


First computer sold commercially


1962


First computer game invented


1977


First cell phone demonstrated


1981


First laptop computer sold


1984


First digital camera demonstrated


1994


World Wide Web is born


CELL PHONES


MEMS help cell phones
work more efficiently as
they switch between
different cell phone bands
and internal functions


MEMS microphones made
their move into cell phones
as a higher
-
quality
replacement to the
condenser electrets
microphones currently used

G_S_cases_accessories_online_s/3.htm


Cell phones use
nanotechnology for
pedometers, texting,
and games


Cell phones have an
anti
-
microbial coating


http://www.recyclersofoklahoma.com/services


The movement of
electrons through
these layers is what
creates light. The entire
structure is 100 to 500
nanometers thick.


Cell phones use OLEDs
consisting of three
layers. It has a layer of
plastic or glass which
removes electrons
when current flows
through it, a layer that
emits light, and another
that injects electrons
when current flows
through it.

DIGITAL CAMERAS AND CAMCORDERS


MEMS inertial sensors
are used for image
orientation and
stabilization.


Use of gyro sensors
detect and compensate
for camera shake in
camera

COMPUTERS


MEMS device called a
silicon microphone is
being used in
computers


Cooling fans used in
computers are coated
with carbon nanotubes
in order to reduce heat

PRINTER PAPER



Nanotechnology plays a big
role in paper production.
Kodak’s
Ultima

Photo Paper
with COLORLAST technology
has 9 layers of ceramic
nanoparticles

and other
coating materials that make
it far more resistant to heat,
humidity, light, and ozone.
As a result, the photos
won’t fade nearly as fast
and will last for more than
100 years.

GAMING


Nintendo uses a MEMS
accelerometer sensor
built right inside the
game cartridge making
it an integral part of
game play.

SUBWOOFER


MEMS accelerometers
are used in subwoofers
to measure and correct
for sound distortion.

through on
-
screen
menus through pointing
and clicking.

TOYS


Nanotechnology is
finding its way into
toys. Stuffed animals
are filled with memory
foam which is infused
with silver
nanoparticles to keep
them germ

MyVu


MyVu relies on the use
of a tiny MEMS mirror
to project an image.

SEGWAY SMART MOTION


Segways

have a cluster of
MEMS gyro sensors and
accelerometers to
provide balance just like
you are walking.


The internal sensors
detect shifts in movement
and then make the
necessary adjustments to
maintain balance.

WII MOTION PLUS


Wii Motion Plus, like in
the Wii Resort, uses a
gyro sensor to help
detect movement along
six different axes, such
as rotation and twist.
