  • Transcript of "Integrates Electronic Devices Into Textiles, Like Clothing"

    1. 1. The Future of Organic Electronics Jaya Movva Ben Spearin Jon Anderson Joshua Wrazen
    2. 2. Inorganic vs. Organic <ul><li>Organic electronics, or plastic electronics, is the branch of electronics that deals with conductive polymers, which are carbon based. </li></ul><ul><li>Inorganic electronics, on the other hand, relies on inorganic conductors like copper or silicon. </li></ul>Silicon sample Carbon sample
    3. 3. Benefits and Obstacles <ul><li>Organic electronics are lighter, more flexible, and less expensive than their inorganic counterparts. </li></ul><ul><li>They are also biodegradable (being made from carbon). </li></ul><ul><li>This opens the door to many exciting and advanced new applications that would be impossible using copper or silicon. </li></ul><ul><li>However, conductive polymers have high resistance and therefore are not good conductors of electricity. </li></ul><ul><li>In many cases they also have shorter lifetimes and are much more dependant on stable environment conditions than inorganic electronics would be. </li></ul>

    5. 5. Organic Light Emitting Diodes (OLEDs) <ul><li>An OLED is a thin film LED in which the emissive layer is an organic compound. </li></ul><ul><li>When this layer is polymeric (or plastic), OLEDs can be deposited in rows and columns on a screen using simple printing methods that are much more efficient than those used in manufacturing traditional LEDs. </li></ul><ul><li>A key benefit of </li></ul><ul><li>OLEDs is that </li></ul><ul><li>they don’t need </li></ul><ul><li>a backlight to </li></ul><ul><li>function. </li></ul>
    6. 6. How it Works <ul><li>An electron and hole pair is generated inside the emissive layer by a cathode and a transparent anode, respectively. </li></ul><ul><li>When the electron </li></ul><ul><li>and hole combine, </li></ul><ul><li>a photon is </li></ul><ul><li>produced, which </li></ul><ul><li>will show up as a </li></ul><ul><li>dot of light on the </li></ul><ul><li>screen. </li></ul><ul><li>Many OLEDs together on a screen make up a picture </li></ul>
    7. 7. <ul><li>Less expensive to produce </li></ul><ul><li>Wide range of colors and viewing angle </li></ul><ul><li>Consumes much less energy than traditional LCDs. </li></ul><ul><li>Flexible and extremely thin </li></ul><ul><li>Limited lifetime of about 1,000 hours. </li></ul><ul><li>Susceptible to water </li></ul>
    8. 8. Organic transistors <ul><li>INTRODUCTION </li></ul><ul><li>Organic transistors are transistors that use organic molecules rather than silicon for their active material. This active material can be composed of a wide variety of molecules. </li></ul><ul><li>Advantages of organic transistors: </li></ul><ul><ul><li>Compatibility with plastic substances </li></ul></ul><ul><ul><li>Lower temperature is used while manufacturing (60-120 °C) </li></ul></ul><ul><ul><li>Lower cost and deposition processes such as spin-coating, printing and evaporation </li></ul></ul><ul><ul><li>Less need to worry about dangling bonds( simplifies the process) </li></ul></ul><ul><li>Disadvantages of organic transistors: </li></ul><ul><ul><li>Lower mobility and switching speeds compared to Si </li></ul></ul><ul><ul><li>wafers </li></ul></ul><ul><ul><li>Usually does not operate under invasion mode. </li></ul></ul><ul><ul><li>Example of an organic transistor (on the side) </li></ul></ul>
    9. 9. Organic Thin film transistors(OTFTS) <ul><li>TFTs are transistors created using thin films, usually of silicon deposited on glass. The deposited silicon must be crystallized using laser pulses at high temperatures. OTFTs active layers can be theramlly evaporated and deposited on any organic substrate (a flexible piece of plastic) at much lower temperatures. </li></ul><ul><li>Benefits of an OTFT: </li></ul><ul><ul><li>Does not require glass substrate as </li></ul></ul><ul><ul><li>amorphous Si does. It could be made </li></ul></ul><ul><ul><li>on a piece of plastic. </li></ul></ul><ul><ul><li>Manufactured at lower temperatures </li></ul></ul><ul><ul><li>Deposition techniques could reduce </li></ul></ul><ul><ul><li>costs dramatically. </li></ul></ul><ul><li>Challenges involved: </li></ul><ul><ul><li>Workarounds for complications with photo resists. </li></ul></ul><ul><ul><li>To find organic semiconductors with high enough </li></ul></ul><ul><ul><li>mobilities and </li></ul></ul><ul><ul><li>switching times. </li></ul></ul>
    10. 10. Picture of an OTFT made on a plastic substrate <ul><li>FUTURE </li></ul><ul><ul><li>OTFT technology’s application is diverse. </li></ul></ul><ul><ul><li>Organic thin-film transistor (OTFT) technology </li></ul></ul><ul><ul><li>involves the use of organic semiconducting </li></ul></ul><ul><ul><li>compounds in electronic components, </li></ul></ul><ul><ul><li>notably computer displays. Such displays are </li></ul></ul><ul><ul><li>bright, the colors are vivid, they provide fast </li></ul></ul><ul><ul><li>response times (which need to be developed </li></ul></ul><ul><ul><li>in OTFT), and they are easy to read in most </li></ul></ul><ul><ul><li>ambient lighting environments. </li></ul></ul><ul><ul><li>Organic substrates allow for displays to be fabricated on flexible surfaces , rather than on </li></ul></ul><ul><ul><li>rigid materials as is necessary in traditional TFT displays. A piece of flexible plastic might be </li></ul></ul><ul><ul><li>coated with OTFT material and made into a display that can be handled like a paper </li></ul></ul><ul><ul><li>document. Sets of such displays might be bundled, producing magazines or newspapers </li></ul></ul><ul><ul><li>whose page contents can be varied periodically, or even animated. This has far-reaching </li></ul></ul><ul><ul><li>ramifications. For example, comic book characters might move around the pages and </li></ul></ul><ul><ul><li>speak audible words. More likely, such displays will find use in portable computers and </li></ul></ul><ul><ul><li>communications systems. </li></ul></ul>

    12. 12. Production and Applications <ul><li>Quicker Checkout </li></ul><ul><li>Inventory Control </li></ul><ul><li>Reduced Waste </li></ul><ul><li>Efficient flow of goods from manufacturer to consumer </li></ul>
    13. 13. Production Specifications of Manufacturing a Nano-RFID <ul><li>> 96 bits </li></ul><ul><li>Four main communication Bands: 135KHz, 13.56MHz, 900MHz, 2.4 GHz </li></ul><ul><li>Vacuum Sublimation </li></ul>
