Piezoelectric transducers are also revolutionizing in-cabin safety features. Tesla's Cybertruck employs millimeter-wave piezoelectric arrays for occupant presence detection, achieving sub ...

This paper presents a high-performance piezoelectric micromachined ultrasonic transducer (PMUT) array with a stress-release (SR) structure. The PMUT array is a multilayer stacked structure that ...

The MPPT solution is obtained using the proposed fractional differential voltage (FDV) method, which is implemented by sampling the peak voltage and inversion voltage of the working piezoelectric ...

It’s built around a flexible disc (about 10.5 cm across) packed with multiple, highly sensitive piezoelectric ... sensor device enabling handheld sensing of heart sounds by untrained users. IEEE ...
