Tactile Sensor Skin


We combined "Nonlinear tactile element" and "Cell-bridge system" to develop a 2x2 sensor array.
CMOS LSI sensor/communication chips are arranged at the boundaries of the sensor elements.
The chips measure the capacitances between the conductive layers and send signals through the same layers.
