  • Patent number: 11118987
    Abstract: A torque sensor including an annular deformation body disposed so as to surround a circumference of a rotation axis, an exertion support body, a fixing support body, and a detection circuit. The annular deformation body has four coupling parts, and four detection parts positioned between two coupling parts which are adjacent in the circumferential direction of the annular deformation body, the detection parts undergoing elastic deformation by exertion of torque. The detection parts each are formed in a convex shape on one side in a direction along the rotation axis and are formed in a concave shape on the other side in a direction along the rotation axis. The detection circuit outputs electric signals on the basis of elastic deformation undergone to the detection part of the annular deformation body.

  • Patent number: 11085837
    Abstract: A force sensor may comprise a sense die comprising a top part and a bottom part. Generally, the top part may comprise a first surface and a second surface, and the bottom part may comprise a first surface for direct contact with a substrate. Typically, the bottom part may be formed by removing a portion of the material of the sense die around the edges of a first face of the sense die. Typically, adhesive may replace the portion of the sense die material removed from the edges of the first face of the sense die. Thus, the adhesive may secure the first surface of the bottom part of the sense die directly to the substrate without serving as an interface between the bottom part of the sense die and the substrate.
