A high-sensitivity tactile sensor based on piezoelectric polymer PVDF coupled to an ultra-low voltage organic transistor

Abstract This paper reports on a highly sensitive tactile sensor based on a floating gate organic transistor called Organic Charge Modulated FET coupled with a flexible piezoelectric polymer (namely a film of polyvinylene fluoride, PVDF). The proposed device is able to reliably transduce pressures as low as 300 Pa, thus opening up interesting perspectives for flexible and low-cost tactile sensors for e-skin applications.
