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, ...

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 ...

A major advantage of atomic force microscopes (AFMs) is their versatility in integrating various operational modes that assess different material properties and functionalities. Among the most ...

A scheme of simple band-pass RC- and LR- filters on operational amplifiers containing only one capacitor or inductor and 3 resistors is proposed. A comparison is made of the amplitude-frequency ...

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 ...
