Abstract
An apparatus includes an integrated circuit configured to be operatively coupled to a sensor array that is configured to generate an ultrasonic wave. The integrated circuit includes a transmitter circuit configured to provide a first signal to the sensor array. The integrated circuit further includes a receiver circuit configured to receive a second signal from the sensor array in response to providing the first signal. The sensor array includes an ultrasonic transmitter configured to generate the ultrasonic wave in response to the first signal and a piezoelectric receiver layer configured to detect a reflection of the ultrasonic wave.
