2KEY TERMSMEMS – three dimensional objects that perform a mechanical function, whose dimensions are between 1 to 100 micrometersNanoparticle – a particle of material at the nanoscaleNanotechnology – a material or structure purposefully manufactured with dimensions between 1 and 100 nanometers to leverage the unique properties it has at that size
3Inertial 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“
4OLED – 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 electrodesSilicon Microphone - are more compact than traditional microphone systems because they capture sound and convert it to a digital signal on the same chip.
5Carbon 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, which is significantly larger than any other material.MEMS Accelerometer - MEMS accelerometers detect and measure motion, vibration, rotational spinning or sliding, and gravitational acceleration.
6Silver 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

10WHY 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
11TECHNOLOGICAL ADVANCES TIMELINE 1826 – First photographic image taken with a camera1951 – First computer sold commercially1962 – First computer game invented1977 – First cell phone demonstrated1981 – First laptop computer sold1984 – First digital camera demonstrated1994 – World Wide Web is born
12CELL PHONESMEMS help cell phones work more efficiently as they switch between different cell phone bands and internal functionsMEMS microphones made their move into cell phones as a higher-quality replacement to the condenser electrets microphones currently used
13Cell phones use nanotechnology for pedometers, texting, and games Cell phones have an anti-microbial coating
14Cell phones use OLEDs consisting of three layers 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.
15DIGITAL 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
16COMPUTERSMEMS device called a silicon microphone is being used in computersCooling fans used in computers are coated with carbon nanotubes in order to reduce heatbuy-notebook.net/tag/computer-notebook/
17PRINTER PAPERNanotechnology 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.
18GAMINGNintendo uses a MEMS accelerometer sensor built right inside the game cartridge making it an integral part of game play.
19SUBWOOFERMEMS accelerometers are used in subwoofers to measure and correct for sound distortion.
20TELEVISIONSMEMS inertial sensors allow you to navigate through on-screen menus through pointing and clicking.
21TOYSNanotechnology is finding its way into toys. Stuffed animals are filled with memory foam which is infused with silver nanoparticles to keep them germ-free.
22MyVu MyVu relies on the use of a tiny MEMS mirror to project an image.
23SEGWAY SMART MOTIONSegways 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.
24WII MOTION PLUSWii Motion Plus, like in the Wii Resort, uses a gyro sensor to help detect movement along six different axes, such as rotation and twist.
25Nanotechnology is a young and growing field An estimated two million skilled nanotechnology workers will be needed worldwide by the year 2015 – one million of them in the U.S.Graduates are receiving salary offers up to $55,000 per year with a two-year degreeGraduates with a baccalaureate degree can expect salary offers up to $65,000 per yearStudents who choose to continue their education can expect salary offers of $100,000
