Abstract

Piezoelectric Sensor In article number 2212538, Jae-Hyun Ryou and co-workers develop a highly sensitive and mechanically flexible piezoelectric sensor using an ultrawide-bandgap single-crystalline AlN semiconductor thin film that can operate at higher than 900 °C. The operation temperature is believed to be amongst the highest for pressure sensors, and the inherent properties of AlN indicate that this approach offers a new solution for sensing in extreme environments often faced in current and next-generation energy, transportation, and defense applications.
