A remarkable new material has recently become available that has an enormous number of potential applications. It is called QTC (Quantum Tunnelling Composite), and has won many major awards for innovation. Its name may sound complex, but what it does is essentially quite easy to understand - when you squeeze it, its electrical resistance drops. In fact it changes from an almost perfect electrical insulator to near metallic conduction levels when a force is applied to it. Thus, the change in the resistance of QTC when it is compressed means that it can be used as a switch. If a pill of QTC is connected in a circuit, together with a battery and an electric motor, then the harder the QTC is squeezed, the more it conducts electricity, and the faster the motor will run. In this way, it behaves as an infinitely variable resistor.The kit includes pieces of QTC, connecting wires, and an electric motor. Full instructions are provided, which allow you to carry out various experiments with this unusual material.It is a rubber like material, and can be made to different specifications so that it is sensitive to a lighter finger-touch or to very large forces.Write a review about: Quantum Tunnelling CompositeAsk a question about: Quantum Tunnelling CompositePeople who bought this item also bought:
