3. What is QTC QTC in brief Simple QTC implementations Advantages of using QTC Future prospects Topics To Be Discussed :

4. QTC (Quantum tunneling composite) is a flexible polymer that exhibits extraordinary electrical properties. In its normal state it is a perfect insulator, but when compressed it becomes a more or less perfect conductor and able to pass very high currents. Electron microscope image of QTC What is QTC??

5. Force-conduction level of QTC material:

6. Quantum Tunneling Composite is a new class of electrically conductive material QTC Material is a patented technology developed in the UK by Peratech Limited based on original discoveries by David and Chris Lussey , the company's founders. First produced in 1996 . While in an unstressed state the QTC Material is a near-perfect insulator; with any form of deformation the material starts to conduct QTC usually comes in the form of pills or sheet QTC In Brief:

7. QTC pills are magnetic too. Nothing like having some magnets laying around on the table while you work. The sheets are composed of one layer of QTC, one layer of a conductive material, and a third layer of a plastic insulator. While QTC sheets switch quickly between high and low resistances, QTC pills are pressure sensitive variable resistors.

13. ADVANTAGES Of QTC

14. QTC material is a pressure/force sensing material. Can be formed or molded into virtually any size, thickness or shape. Simple and reliable to use. Durable - it has no moving parts to wear out. Mechanically strong. Can be made to withstand extreme temperatures limits. Advantages Are-

15. Versatile, both electrically and physically e.g. Its range and sensitivity can be altered. Intrinsically safe - the material is a contactless switch, ideal for spark free operation. Can be directly interfaced to standard electronic and electrical devices Can be customized for customer requirements, applications and products.
