Abstract
A capacitive strain sensor comprises a substrate ( ) and a pair of interdigital electrode capacitors ( A) formed on the substrate. A dielectric thick film ( ) having a uniform thickness and made of a material the dielectric constant of which varies with strain is provided on an elastic body having a flat or curved surface on the substrate ( ). A block ( ) for preventing strain from being produced is secured to one end of the substrate ( ); a weight ( ) is secured to the other end. The capacitors ( A) are formed by interdigitally arranging a pair of electrodes being parallel linear electrodes of linear conductors on the substrate.
