Fast Photostriction in Ferroelectrics (Small 7/2022)

Ferroelectrics In article number 2106275, Kui Yao and co-workers describe a strategy to achieve high rate dynamic photostriction and ultrasonic waves by utilizing local fast responses in a ferroelectric material under modulating continuous light excitation in the resonance condition. The fast photostrictive effect offers a non-thermal approach to excite mechanical vibration and ultrasound remotely for non-contact ultrasonic structural health monitoring, such as for the aerospace industry.
