Abstract:
1. A flexible capacitive tactile sensor comprising: a flexible first electrode layer including a single ground electrode covering entire area of said sensor, a flexible second electrode layer including at least a first group of electrodes connected individually to a first capacitance-sensing integrated circuit, and a second group of electrodes connected individually to a second capacitance-sensing integrated circuit, and a flexible compressible dielectric layer separating said first and said second electrode layers, wherein said ground electrode of said first electrode layer is electrically connected to said first and said second integrated circuits, whereby said first group of electrodes together with said ground electrode and said dielectric layer forming a first group of capacitance sensors, said second group of electrodes together with said ground electrode and said dielectric layer forming a second group of capacitance sensors, said first and second groups of capacitance sensors together forming said tactile sensor, said first and second integrated circuits configured to operate said respective first and second groups of capacitance sensors and collect pressure data therefrom.
