  • Publication number: 20150187961
    Abstract: The present disclosure relates to a piezoresistive sensor that improves measurement precision by using a piezoresistive pattern that increases a piezoresistive deformation rate. An embodiment of the present disclosure provides a piezoresistive sensor that may include: a semiconductor substrate, four beams formed as a cross-shape with reference to a central body of the semiconductor substrate, and sixteen piezoresistive patterns formed on a top of the four beams, wherein sixteen piezoresistive patterns are formed as an “X” shape and are disposed on the four beams so as to form four piezoresistive pattern groups.

  • Patent number: 8671780
    Abstract: Disclosed is a strain gauge type force-torque sensor and a method for manufacturing the same. More specifically, a first sensor structure having a convex part on a bonding surface thereof and a second sensor structure having a concave part bonded to the convex part of the first sensor structure are formed. The gauge film is formed by installing a strain gauge on a flexible film. The gauge film is compressively interposed between the bonding surface of the first sensor structure having the convex part and a bonding surface of the second sensor structure having the concave part to initially deform the gauge film. The first sensor structure and the second sensor structure are fixed to each other in a state where the gauge film is initially deformed.
