Learn how 4D digital holographic microscopy provides real-time, non-contact measurement of MEMS micromirror deformation, ...

With loudspeakers, an important parameter is the frequency at which their cones resonate. This clever Arduino-based tester ...

The efficiency of wireless charging systems is limited by power loss occurring due to frequency changes in the resonant circuits that enable power transfer. These necessary modulations reduce ...

An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...
