Title:
FORCE SENSOR, SENSOR ARRAY INCLUDING SAME, AND GRIPPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/033455
Kind Code:
A1
Abstract:
A force sensor (1) comprising: a first resin body (11) positioned on a substrate (9), the first resin body (11) sealing a light-emitting element (5) and a light-receiving unit (7), and transmitting emitted light from the light-emitting unit (5); a reflective surface (13a) that reflects light from the light-emitting element (5) toward the light-receiving unit (7); and an outer layer (13) positioned on the side of the first resin body that is opposite from the substrate, the outer layer (13) having greater hardness than the first resin body. The light-emitting element (5) is positioned between two straight lines (L1, L2) that are orthogonal to a line segment (Ls) connecting a first light-receiving element (7a) and a second light-receiving element (7b), and that pass through respective end points (Pe1, Pe2) of the line segment (Ls). The reflective surface (13a) is positioned on the substrate side of the outer layer (13), or is positioned between the outer layer (13) and the light-emitting element (5). The reflective surface (13a) is inclined or curved relative to the direction in which the line segment (Ls) extends.
