The Programmable Paper Circuit Board
Paper Circuit is a novel technology by which you can embed electronics anywhere and everywhere, that too, without using wires. And the Paper Tronics lets you add sensors, microcontrollers, and touchpads so that you can Automate the process and build more interactive projects.
A Reed switch is an electromagnetic switch used to control the flow of electricity in a circuit. They are made from two or more ferrous reeds encased within a small glass tube-like envelope, which become magnetised and move together or separate when a magnetic field is moved towards the switch.
The switching mechanism is comprised of two ferromagnetic blades, separated by only a few microns. When a magnet approaches these blades, the two blades pull toward one another. Once touching, the blades close the normally open (NO) contacts, allowing electricity to flow
Reed sensors facilitate opening and closing of automatic doors. They also serve as proximity contacts for security devices used on doors and windows, or in devices that use a clamshell design. Introduction to PaperTronics – The Programmable reed switch
