CONSUMER EDUCATION
KEY TERMS
 MEMS – three dimensional objects that perform a
mechanical function, whose dimensions are between
1 to 100 micrometers
 Nanoparticle – a particle of material at the nanoscale
 Nanotechnology – a material or structure
purposefully manufactured with dimensions
between 1 and 100 nanometers to leverage the
unique properties it has at that size
Inertial sensors – can detect and measure
acceleration, tilt, shock, vibration, rotation, and
multiple degrees-of-freedom (DoF) motion, and
enable a wide range of market-differentiating
industrial, medical, communications, consumer
and automotive applications.

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
http://en.wikipedia.org/wiki/Oled
 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-todiameter ratio of up to 132,000,000:1,[1] which is
significantly larger than any other material.
http://en.wikipedia.org/wiki/Carbon_nanotube
 MEMS Accelerometer - MEMS accelerometers detect
and measure motion, vibration, rotational spinning
or sliding, and gravitational acceleration.
 Silver ion – technically speaking, a silver ion is an
atom of silver that is missing one electron

 MyVu - refers to a product family of wearable video
display glasses released by Myvu Corporation
proving increased viewing usability and portability
for users

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
http://www.phonecasestore.com/iPhone_3g_Case_iPhone_3
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
• 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.
• The movement of
electrons through
these layers is what
creates light. The entire
structure is 100 to 500
nanometers thick.
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
http://miniandminiall.blogspot.com/2011/03/jvcgrd230-minidv-digital-camcorder.html?amp
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
http://buy-notebook.net/tag/computer-notebook/
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.
http://www.jjmehta.com/products/nintendowii_console.html
SUBWOOFER
• MEMS accelerometers
are used in subwoofers
to measure and correct
for sound distortion.
http://www.subwoofersforsale.net/
TELEVISIONS
• MEMS inertial sensors
allow you to navigate
through on-screen
menus through pointing
and clicking.
http://www.electronicempire.co.uk/televisions/3d-tvs/lg-50px990-50-full-hd-600hz-3d-plasma-tv
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-free.
http://meghan-mccarthy.com/fair_stuffedanimals.html
MyVu
• MyVu relies on the use
of a tiny MEMS mirror
to project an image.
http://electronics.howstuffworks.com/gadgets/travel/video-glasses.htm
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.
