  • Publication number: 20230126952
    Abstract: Provided are a surface stress sensor that enables deterioration in measurement precision to be suppressed and a method for manufacturing the same. A surface stress sensor includes: a membrane configured to be bent by applied surface stress; a frame member configured to surround the membrane with gaps interposed therebetween when viewed from the thickness direction of the membrane; at least a pair of coupling portions configured to couple the membrane and the frame member; a flexible resistor configured to be disposed on at least one of the coupling portions and have a resistance value that changes according to bending induced in the coupling portion; and a support base member configured to be connected to the frame member and overlap the frame member when viewed from the thickness direction of the membrane, in which a cavity portion is disposed between the membrane and the support base member.
