Abstract:
An apparatus and method for determining the depth of an object below a surface or the thickness of the dermis. The apparatus and method use a plurality of piezoelectric fingers having probes with differently sized contact areas. A plurality of measurements is taken using each of the probes with differently sized contact areas in order to determine the depth of an object below a surface or the thickness of the dermis.
