  1. NANOTECHNOLOGY IN CONSUMER EDUCATION

  2. 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

  3. 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

  4. OLED – An organic light emitting diode (OLED) is a light-emitting diode (LED) in which the emissiveelectroluminescent 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.

  5. 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. http://en.wikipedia.org/wiki/Carbon_nanotube • MEMS Accelerometer - MEMS accelerometers detect and measure motion, vibration, rotational spinning or sliding, and gravitational acceleration.

  6. 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 wearablevideo display glasses released by Myvu Corporation proving increased viewing usability and portability for users http://en.wikipedia.org/wiki/Myvu

  7. UNIT OBJECTIVES • Why nanotechnology? • Identify technological advances in history. • Describe how cell phones use nanotechnology. • Identify nanotechnology in digital cameras and camcorders. • Discuss nanotechnology in computers.

  8. Name ways nanotechnology is integrated in printer paper. • Describe nanotechnology in gaming. • Identify ways nanotechnology is used in subwoofers. • Discuss nanotechnology in televisions. • Describe nanotechnology integration in toys. • Name ways nanotechnology is used in MyVu.

  9. Describe the impact of nanotechnology use in segways. • Identify nanotechnology in Wii Motion Plus. • List expected salaries for skilled nanotechnology workers. • List Oklahoma schools offering courses in nanotechnology.

  10. 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

  11. 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

  12. 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_3G_S_cases_accessories_online_s/3.htm

  13. Cell phones use nanotechnology for pedometers, texting, and games • Cell phones have an anti-microbial coating http://www.recyclersofoklahoma.com/services

  14. 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.

  15. 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/jvc-grd230-minidv-digital-camcorder.html?amp

  16. 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/ buy-notebook.net/tag/computer-notebook/

  17. 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

  18. 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

  19. SUBWOOFER • MEMS accelerometers are used in subwoofers to measure and correct for sound distortion. http://www.subwoofersforsale.net/

  20. 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

  21. 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

  22. MyVu • MyVu relies on the use of a tiny MEMS mirror to project an image. http://electronics.howstuffworks.com/gadgets/travel/video-glasses.htm

  23. 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/prhtml03/03553.html

  24. 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/

  25. 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

  26. OKLAHOMA SCHOOLS OFFERING COURSES • Oklahoma City Community College • Oklahoma State University • Oklahoma University • Tulsa Community College • Tulsa University
