NANOTECHNOLOGY IN 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. http://www.analog.com/en/sensors/inertial-sensors/products/index.html 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“ http://us.wii.com/iwata_asks/wiimotionplus/vol1_page1.jsp 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, 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 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 http://en.wikipedia.org/wiki/Myvu UNIT OBJECTIVES 1.

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. www.officemax.com 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. http://www.cpsc.gov/cpscpub/prerel/prhtml03/0355 3.html 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. http://www.andriasang.com/e/blog/2009/09/03/black_wii_motion_plus/images/ 2132390771/ Nanotechnology 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 degree Graduates with a baccalaureate degree can expect salary offers up to $65,000 per year Students who choose to continue their education can expect salary offers of $100,000 OKLAHOMA SCHOOLS OFFERING COURSES Oklahoma City Community College Oklahoma State University Oklahoma University Tulsa Community College Tulsa University REFERENCES • • • • www.azonano.com http://www.digitivity.com/articles/2008/08/applications-of-nanotechnology http://www.nanowerk.com/news http://www.understandingnano.com • Richard Booker and Earl Boysen, Nanotechnology for Dummies, Indianapolis, Indiana, 2005.
