Photoacoustics is the study of vibrations induced in matter by light. Laser light causes localised heating when it is absorbed by a surface. This in turn makes the target area expand and sends a ...
Abstract: MEMS vector hydrophones are poised to become the core devices of miniaturized underwater acoustic sensing. However, existing MEMS vector hydrophones suffer from low sensitivity and shallow ...
Abstract: Piezoelectric acoustic emission (AE) sensors, characterized by their simple structure, high sensitivity, and wide frequency bandwidth, demonstrate significant potential for applications in ...
