ABSTRACT:
A force sensor detects adhesion between a subject and a substrate through an adhesive. The sensor is embedded in the adhesive and is formed by two members which are displaceable relative to each other. A readout scheme detects displacement of the two members due to a force and reaction forces acting upon the sensor through the adhesive. Fiber optics may be employed in the readout scheme to provide an indication of displacement of the two members and thereby adhesion of the subject to the substrate.
