Abstract :
This paper presents the identification of a lumped parameters model of a POSFET tactile sensor which aims to give the sense of touch to humanoid robots. A Cole-Cole model has been design in order to describe the dynamic of dielectric relaxation of the PVDF-TrFE piezoelectric polymer. The tactile sensor has been characterized in time and frequency domain. The parameters of the model have been estimated from the time domain response and validated in frequency domain.
