Transport properties of nonhomogeneous segregated composites
B. Nigro, G. Ambrosetti, C. Grimaldi +2
In conductor-insulator composites in which the conducting particles are dispersed in an insulating continuous matrix the electrical connectedness is established by interparticle qu…
Critical behavior of the piezoresistive response in RuO2-glass composites
C. Grimaldi, T. Maeder, P. Ryser +1
We re-analyse earlier measurements of resistance R and piezoresistance K in RuO2-based thick-film resistors. The percolating nature of transport in these systems is well accounted…
Longitudinal and transversal piezoresistive response of granular metals
C. Grimaldi, P. Ryser, S. Straessler
In this paper, we study the piezoresistive response and its anisotropy for a bond percolation model of granular metals. Both effective medium results and numerical Monte Carlo calc…
Gauge factor enhancement driven by heterogeneity in thick-film resistors
C. Grimaldi, P. Ryser, S. Straessler
We present a simple picture of the gauge factor (GF) enhancement in highly heterogeneous materials such as thick-film resistors. We show that when the conducting phase is stiffer t…
