ABSTRACT:
An apparatus and method directed to a solid-state capacitance sensor for measuring a strain force on a dielectric including at least one pair of electrostriction sensors each sensor having at least two electrodes and each having a central axis. The central axes are disposed in a common plane and are oriented substantially mutually perpendicularly to one another. Preferably, at least two pairs of sensors, forming a rosette, are provided to facilitate multi-component analysis of a sample having dielectric properties under stress/strain.
