Abstract
A hydrogen sensor includes a substrate, a first terminal, and a second terminal. The first and second terminal are disposed on the substrate and separated by a gap. An organic semiconductor is electrically coupled to the first terminal and the second terminal. Exposure of the organic semiconductor to hydrogen de-dopes the organic semiconductor of oxygen. Conductivity of the organic semiconductor thereby decreases upon exposure to hydrogen.

A hydrogen sensor comprising:
- a substrate;
- a first terminal disposed on the substrate;
- a second terminal disposed on the substrate;
- and
- an organic semiconductor electrically coupled to the first terminal, and the second terminal,
- wherein conductivity of the organic semiconductor decreases upon exposure to hydrogen.
The hydrogen sensor of claim wherein the hydrogen sensor is a resistive-type sensor, wherein the first terminal includes a first electrode and wherein the second terminal includes a second electrode.
A system for detecting hydrogen, the system including:
- an organic hydrogen sensor including:
- a first terminal,
- a second terminal physically separated from the first terminal by a gap, and
- an organic semiconductor electrically coupled to the first terminal and the second terminal;
- a processing circuit electrically coupled to the first terminal and the second terminal,
- wherein the processing circuit transmits an input signal to one of the first terminal and the second terminal and receives an output signal from one of the first terminal and the second terminal.
