Quantum+Tunnelling+Composite

=What is QTC?=

Quantum tunnelling 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 electrical conductor enabling high currents to flow through a circuit.



QTC contains tiny metal particles which enable electrons to pass through the insulation in between by a process called quantum tunnelling.

The recent discovery of QTC has resulted in much excitement in the product design world where it could soon revolutionise many of the products we commonly use today.

QTC is currently available in three forms: pills, thin sheet or cable. Each form of QTC offers different possibilities for practical use, but all exhibit striking resistance change when deformed by squeezing, pulling or twisting. In practice, the different forms of QTC can be connected in quite simple ways to create anything from switches to force sensors.



The example below, is of an led pocket torch that uses a QTC pill as a switch - much more effective than the mechanical ones we normally use.
