Ultrasonic ranging has been widely used in automobiles, unmanned aerial vehicles (UAVs),
robots and other fields. With the appearance of micromachined ultrasonic transducers …

In this work, novel airborne capacitive micromachined ultrasonic transducers (CMUTs)
based on a dual-backplate (DBP) technology are presented. In contrast to conventional …

This work presents a low power ultrasonic transceiver line array enabling energy efficient
airborne object detection. The line array is based on capacitive micromachined ultrasonic …

We demonstrate the transmission of ultrasound in air using a device that resembles a MEMS
microphone in its construction. The device has a 1 mm diameter diaphragm and uses a …

This contribution describes the concept and implementation of a wearable arm gesture
recognition system. The system relies on an ultrasound body area network for …

The point source superposition method based on the Rayleigh integral model is time-
consuming for calculating the three-dimensional spatial sound field. In this paper, the look …
