  • Piezoresistive gauge formed by an electrically conductive organic compound
    Patent number: 4535317
    Abstract: The present invention relates to a piezoresistive gauge. This gauge comprises a support, on which are formed two pairs of electrical contacts, partly covered with a piezoresistive element, made from an electricity-conducting organic compound, chosen from among the salts of tetramethyl-tetrathiofulvalene, quaternary ammonium salts of tetracyanoquinodimethane and diethyl-dimethyl-tetrathiofulvalene-tetracyanoquinodimethane (DEDMTTF-TCNQ).This gauge can be used for measuring pressures of approximately 500 bars to a few kbars.
