A new system called Electrick (developed by Researchers at Carnegie Mellon University Pittsburgh) uses conductive spray paint and electrodes to turn any surface into an electronic touch sensor.
Electric Field Tomography
The revolutionary new system was created by Created by CMU Ph.D. student Yang Zhang and works using a technique known as electric field tomography (EFT), which exploits the interaction of a high-frequency electric field with a conductive medium.
How Does It Work?
In short, a surface or object is coated with a spray-paint application of carbon conducting paint. N.B. whole, solid or pliable objects can also be cast / moulded from carbon-conductive material (a mixture of carbon fibre and conventional silicone).
