Piezoresistive Sensor Based on Micrographite-Glass Thick Films.

ABSTRACT: A new Pb-free glass containing several oxides (Bi₂O₃, B₂O₃, SiO₂, Al₂O₃ and ZnO) with sintering temperature reduced down to 600 °C has been developed for applications in a piezoresistive pressure sensor. Using this low sintering temperature glass, it was possible to fabricate micrographite-based pastes and piezoresistive films without losses of graphitic material during the sintering. Good adherence of the films onto alumina substrates was observed and attributed in part to the reactions of ZnO and Bi₂O₃ with alumina substrates. Piezoresistive films with uniformly distributed micrographite particles were produced using sodium carboxymethyl cellulose (NaCMC) in aqueous solutions during the pre
