A 3D-printed piezoelectric metamaterial uses topology-driven charge transport to locate underwater sound sources from a single compact transducer, replacing bulky hydrophone arrays.

Capacitive displacement sensor’s touch-free nature makes it ideal for fragile surfaces and high-speed machinery.

Piezoelectric materials, which convert mechanical stress into electricity and vice versa, are essential components in sensors, actuators, and energy-harvesting devices. However, the best piezoelectric ...

Researchers at University of Tsukuba have developed a noncontact vibration measurement method using an event camera, a sensing technology inspired by biological vision. By applying geometric analysis ...
