The plastic sheets can be made to different sizes like the credit card size and circular pads designed for electronic drum pads shown here
Resistance touch technology, which generally relies on the use of a stylus or similar instrument, typically detects touch by measuring changes in electrical resistance. But it can only detect one touch at a time. Touch screen using capacitance technology can detect multiple inputs, but can’t detect pressure. Now researchers at New York University (NYU) are looking to get the best of both worlds with a new type of touch-sensitive pad that responds precisely to pressure and can detect multiple inputs at once.
