Abstract:
1. A device comprising: a flexible pyroelectric substrate; a conductive field-effect transistor (FET) gate, formed on the substrate; an organic gate dielectric, formed on the gate and on the substrate near the gate; a conductive FET source, formed on the gate dielectric near a first edge of the gate; a conductive FET drain, formed on the gate dielectric near a second edge of the gate that is located across the gate from the first edge of the gate; an organic semiconductor FET body region, formed on the gate, the source, and the drain; an organic passivation layer, formed on the semiconductor body region; and wherein the gate, the source, and the drain are configured as a FET amplifier to locally amplify a pyroelectric-generated charge, sensed at the gate from an local region of the substrate that is adjacent to the gate, into a resulting current between the source and drain.
