In this paper, two different piezoresistive thick-firm accelerometers
are presented: a new high-sensitivity cantilever-type printed on a fer
ritic metal substrate and a ceramic twin-mass structure with an elevat
ed figure of merit. Design and development are presented together with
theoretical predictions and FEM analysis. Optimization procedures and
limits are discussed in comparison with experimental results. The ove
rall performance of the devices suggests that with proper control of s
creen-printing and firing processes, many applications in advanced ind
ustrial requirements will be possible in the near future.
