Spatially Transparent Electrical Tactile Sensor


"We developed a sensing technology to measure the touching pressure without restricting touch action. In the proposed method, we attach electrodes to the object and the human skin and apply voltage between them. Because the contact resistance between the object and the human skin changes according to the contact pressure, the system detects the resistance change for estimating the contact pressure. Especially, we have achieved a wide dynamic range by introducing a differential amplifier for the high sensitive sensing. This technology can be used for quantifying the touching and implementing an input interface."
