BPN934: Display Compatible pMUTs


Ultrasonic transducers have been used in many applications from medical imaging to range finding. In recent years, applications have been further expanded to hand-held devices such as fingerprint sensors, and gesture recognitions thanks to advancements in micromachined ultrasonic transducers (MUTs). Compared to conventional ultrasound devices, MEMS ultrasonic transducers have advantages of higher resolution, higher bandwidth, and lower power consumption. More recently, products to interact electronic devices from a distance have been introduced. These products either require an allocated area on the screen or uses a hardware like remote controlled pen.
