Integration of a Low-Voltage Organic Field-Effect Transistor and a Sensing Capacitor for a Pressure-Sensing Device

We integrate a pressure sensing capacitor and a low operation voltage OFET to develop a pressure sensor. The OFET was used as a readout device and an external pressure was loaded on the sensing capacitor. The OFET operates at less than 5 V and the change in the drain currentin response to the pressure load (100 kPa) is two orders of magnitude
