ABSTRACT:
Provided are a method and system for a biometric sensing apparatus. An apparatus includes an input signal generator configured to produce an activation signal. Also includes is a piezoelectric ceramic sensor having a plurality of piezoelectric ceramic elements arrayed and spaced to (i) receive the activation signal (ii) detect one or more features of a digit proximate to the array in accordance with the received activation signal and (iii) produce output signals representative thereof. A processor is coupled to the sensor to process the output signals.
