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

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.

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

www.silver-collids.com 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

• 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. www.officemax.com

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.

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.

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.
