Author presents a fully organic complementary amplifier circuit with a gate dielectric layer of P(VDF-TrFE):PS composite. Thin-film morphologies of dielectric and semiconducting layers are examined vie AFM topographic images. Good balance between low and high noise margins of the circuit is obtained by using different transistor geometry parameters. Experimental measurements indicate that at a supply voltage of 5 V and an input signal frequency of 10 Hz, the maximum gain factor is about 34. The active sensor was made by wiring the amplifier and the printed collision detector with a PVDF piezoelectric material. Collision events can be well detected with the built active sensor.
