In this article, we propose an interface circuit formed by thin film transistor(TFT) for tactile sensing applications. This interface circuit is composed of two TFTs and a capacitor, in connection with a polyvinylidenefluoride (PVDF) transducer for force sensing. An analytical model is presented to explain the working principle of the interface circuit, and an experimental study of a 10×10 tactile sensing array is built to evaluate the feasibility of the circuit. Our study shows such interface circuit is promising to obtain the dynamic and static force sensing.
