    Abstract: An electronic device with an ability to perform touch detection includes an ultrasound touch sensor disposed within a housing and configured to detect physical contact with an exterior surface of the housing. The sensor may emit ultrasonic sound waves, receive reflected ultrasonic sound waves reflected from a surface portion corresponding to the physical contact at the exterior surface of the housing, and compare the reflected ultrasonic sound waves to a stored reflection pattern. Based on determining a match between the reflected ultrasonic sound waves and the stored reflection pattern, the electronic device may activate a function. The sensor may be part of an ultrasound-on-a-chip device.
