Abstract
A touch sensor chip can comprise an ultrasound sensor layer comprising an array of ultrasonic transducers. The array of ultrasonic transducers can comprise one or more ultrasonic transducers. The touch sensor chip can also comprise an integrated circuit layer coupled to the ultrasound sensor layer. The integrated circuit layer can comprise circuitry configured for driving the array of ultrasonic transducers to generate ultrasound signals and receiving reflected ultrasound signals using the array of ultrasonic transducers. The integrated circuit layer can also comprise circuitry configured for generating an energy signal associated with received reflected ultrasound signals.
