EXCESS NOISE IN THICK FILM PIEZORESISTORS ON A STEEL SUBSTRATE

D. Crescini, D. Marioli, E. Sardini, A. Taroni
  • Abstract:
    The work reports the measurements of the excess-noise coming from the thick-film piezo-resistors (TFRs) deposited on metallic substrates. The purpose of this paper is to single out the best combination of conductive, dielectric and piezoresistive inks in order to minimise the electronic noise. At this purpose a comparison between the excess noise measurements made of the same inks and geometric characteristics but screen printed and fired on alumina substrates, are reported. Moreover, the article gives a description of the measurement instrumentation used and, in particular, of the low noise preamplifiers.
