In this paper, we propose a novel piezoelectric micromachined ultrasonic transducer (PMUT) for airborne object detection, which provides high sensitivity compared to the conventional round-shaped PMUT ...

Companies across Europe are developing the next generation of sensors for medical applications, from Covid-19 testing to ...

In this paper, an analytical model of sandwich type piezoelectric transducer using bending vibration mode is presented. The piezoelectric transducer is simplified as a constant cross section composite ...

Piezoelectric actuators and sensors are added for controlling the high frequency vibrations beyond range of motor torque control. Additionally, this work introduces a formulation for simultaneous ...

Vibration energy harvesting with piezoelectric materials is of practical interest because of the demand for wireless sensing devices and low-power portable electronics without external power supply.
