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.
