摘要：

The piezoresistive behaviour based on the quantum tunnelling conduction of a copper-polydimethylsiloxane composite was studied by means of impedance spectroscopy and confirmed by the fitting with the tunnelling piezoresistance mathematical model. This investigation paves the way to the implementation of the impedance spectroscopy technique in the characterization of piezoresistive pressure sensors for robotic application.
