| Abstract: |
A sensor for detecting angular displacement of an object. The sensor comprises a substrate for attachment to the object whose angular displacement is to be sensed and a sensing means attached to the substrate and connectable into an electric circuit. The electric circuit measures the resistance of the sensing means, which changes as a function of the angular displacement. Several embodiments are disclosed, including a conductive elastomer sensor, a conductive ink sensor, a sliding resistor sensor, a force sensitive resistor sensor and a conductive fluid sensor.
