This flexible polymer exhibits extraordinary electrical resistance change when deformed by squeezing, pulling or twisting. In practice, QTC™ can be connected in quite simple ways to create anything from switches to force sensors. In its normal, uncompressed state, QTC acts as a near perfect insulator, but as it is gradually compressed it will allow more current through until it is nearly a perfect conductor. Fun to experiment with and great for turning anything with a screw-in battery compartment into an effective dimmer switch! Can also be used between layers of conductive fabric to make variable switches and variable resistors or capacitors.
It is claimed that electrons ‘pass’ through the insulation by a process called quantum tunneling. In classical physics, the electrons cannot pass through an insulating barrier, but according to quantum theory a wave can – and this is what happens in QTC™. Another way of describing the quantum tunneling effect is to say that a non-zero probability exists of electrons one side of the insulation barrier appearing on the other side.
QTC™ can be used as a solid state switch - in the "off" state it is a good insulator and in the "on" state it is as good as a metal conductor. It can be used to detect even very small changes due to compression, tension or other stresses and it can carry significant currents allowing for the direct control of loads.
Rated for over one million compressions.
Here is a very unique switch. Knitted from polyester and stainless steel fibers, an electrical contact is made when the 4x4 cm patch is compressed. Use it for robotic applications, occupancy sensors (in a seat for example), or intrusion alarms (when stepped on). Also great for artistic purposes: put it in a shoe, or attach it to a garment (glove tip or elbow patch for example) to control lights or sounds when you move. Kit includes 2x3 inch fabric switch, LED bulb, conductive thread, instructions, one CR 2032 3V coin battery with battery holder. Just add your own sewing needle, to make the simple educational project shown.
Knitted pressure sensitive fabric made of three layers. Two layers of stainless steel are separated by one layer of acrylic fabric. When pressed, the two external layers touch, allowing current flow. This basic sensitive fabric has a functioning equivalent to a push button switch. When you press it you close an electrical circuit. This fabric is compatible with the Arduino platform, and it can be connected to an Arduino controller without any additional hardware.
As simple as playing with your zipper. This soft 39 inch fabric potentiometer is perfect for controlling the brightness of an LED or the changing the tone of a buzzer to make cool sound effects. Can also be used as a position sensor. Resistance of this component is changed by sliding the position of the ring.
Compatible with Arduino inputs. Very easy to connect. Kit includes 1 meter of knitted conductive tape, instructions for a simple circuit using a Lilypad Arduino (not included), and a metal ring.
