Strain gauge sensor

Abstract

Abstract PURPOSE:To measure the quantity of light and temperature simultaneously with the measurement of displacement or by switching by providing a resistance strain gauge on a substrate formed of a functional sensitive material such as a piezoelectric material, a photosensitive material, and a temperature sensing material. CONSTITUTION:The substrate 2 is formed of the functional sensitive material such as the piezoelectric material, photosensitive material, and temperature sensitive material. For example, nichrome layers 3 and 3' are vapor-deposition on both surfaces of the substrate 2. In this constitution, one end of the strain gauge sensor 1 is fixed and the other end is displayed X to generate differences in resistance value between terminals C and D, and terminals E and F, so they are converted electrically to measure bending strain. Further, even the quantity of light and temperature can be measured from variation in the resistance value or electricity generation quantity of the substrate 2 formed of the functional sensitive material.
