| 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.

What is claimed is:
1. A sensor for detecting angular displacement of an object comprising:
- a substrate for attachment to the object whose angular displacement is to be sensed;
- sensing means
attached to the substrate and connectable into an electric circuit, the
sensing means comprising a material having an electrical resistance
which changes as a function of the angular displacement, said material
comprising an electrically conductive ink deposited on said substrate,
said conductive ink comprising carbon particles in a binder and further
comprising a solution of a first stretchable ink and a second brittle
ink.
