1. A biometric sensing apparatus comprising:
- an array of piezoelectric ceramic elements;
a set of electronics for excitation of said elements and for monitoring a motion of each of said elements;
said electronics and elements being operable in a first mode for obtaining a first set of data encoding at least one two dimensional image of a fingerprint of a linger, and being operable in a second mode for obtaining a second set of data encoding at least one three-dimensional representation of one or more subcutaneous, tissue structures that are located within tissue that is embedded within said finger; and
whereinsaid electronics being controlled by software that is configured for identifying biometric markers and for recording a quantitative representation of relative locations between biometric markers within and between said fingerprint and one or more of said subcutaneous tissue structures.
