Abstract
An ultrasonic sensor system may include an ultrasonic transceiver layer, a thin-film transistor (TFT) layer proximate a first side of the ultrasonic transceiver layer, a frequency-splitting layer proximate a second side of the ultrasonic transceiver layer and a high-impedance layer proximate the frequency-splitting layer. The frequency-splitting layer may reside between the ultrasonic transceiver layer and the high-impedance layer. The high-impedance layer may have a higher acoustic impedance than the frequency-splitting layer.
