  • Double-side-coated surface stress sensor
    Patent number: 9506822
    Abstract: A double-side-coated surface stress sensor includes a sensing membrane structure portion where at least two ends opposite each other are fixed on a mounting portion; a receptor layer that coats both surfaces of the sensing membrane structure portion; and an element detecting a stress, which is provided in the vicinity of at least one of the fixed two ends, opposite each other, of the sensing membrane structure portion or at least one of the fixed two ends, opposite each other, of the mounting portion, in which in a detection output is obtained from the element based on the stress which is applied onto the receptor layer coating both of the surfaces of the sensing membrane structure portion. Accordingly, it is possible to provide a double-side-coated surface stress sensor which coats both surfaces of the sensing membrane structure portion by the receptor layer, thereby obtaining a sufficiently large detection output.
