Claim 14:
15. An ultrasonic transducing sensor apparatus comprising
a receive sensor;
at least one PMUT mechanically coupled to, and electrically isolated from, the receive sensor via a common flexible membrane, the at least one PMUT to transmit an acoustic waveform via the membrane in response to a drive voltage Vd(t), and
at least once processor configured to provide the drive voltage Vd(t) to the at least one PMUT and modify the drive voltage Vd(t) based on the feedback signal, where the receive sensor is an optical vibration sensor including an optical waveguide and the received waveform, VRO(t), is based on the physical displacement of the optical waveguide by the common membrane.
