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 ...

Piezoelectrical materials are utilized in various applications, from biomedical (cardiac, auditory, ultrasound, and numerous biosensors) to advanced electronics—including energy production and storage ...

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

In a recent study published in the PNAS Nexus, researchers introduced and validated resonance sonomanometry (RSM) for noninvasive, calibration-free continuous blood pressure (BP) measurement using ...

Drawing tablets have been a favorite computer peripheral of artists since its inception in the 1980s. If you have ever used a drawing tablet of this nature, you may have wondered, how it works, ...
