Document Type and Number:
WIPO Patent Application WO/2023/109276
Kind Code:
A1
Abstract:
A tactile sensor (101, 102, 103, 104, 105, 2520), a touch event detection method, a sensing device (2500), and a robot (10), which relate to the field of sensor design. The tactile sensor (101, 102, 103, 104, 105, 2520) comprises a sensing unit (21), an elastic body supporting housing (22) and a base (23), wherein the sensing unit (21) is arranged in an inner cavity enclosed by the elastic body supporting housing (22) and the base (23); and the sensing unit (21) comprises at least two light sources (211), a photodetector (212) and a reflector (213), the photodetector (212) being arranged on the base (23), the at least two light sources (211) being arranged around the photodetector (212) on the base (23), and the reflector (213) being arranged at the top of the inner cavity of the elastic body supporting housing (22). By means of combining a plurality of light sources (211) and one photodetector (212), the number of photodetectors (212) used is reduced, so that the volume of the tactile sensor (101, 102, 103, 104, 105, 2520) is reduced.
