Title:
FORCE SENSOR
Document Type and Number:
WIPO Patent Application WO/2020/202821
Kind Code:
A1
Abstract:
The present invention makes it possible to obtain a highly sensitive force sensor having a small size. In this force sensor, a strain-sensing material is arranged on at least one surface section of a plate-shaped member, strain occurring in the plate-shaped member in response to force being applied to the surface section of the plate-shaped member is sensed by the strain-sensing material, and the force applied to the plate-shaped member is thereby sensed. The strain-sensing material is formed from a strip-shaped conductive material. The strain-sensing material is arranged on the surface section of the plate-shaped member so as to correspond to each of a first ring-shaped area serving as the center of a force application section in which force is applied to the surface section of the plate-shaped member and a second ring-shaped area at a different distance from the force application section than the first ring-shaped area.
