A simplified oscillation system, which consists of two beam-shaped cantilevers, was designed, fabricated and characterised for demonstrating synchronised oscillations and considering the eigenstate (frequency) amplification mechanism for possible sensing applications. Two geometrically different cantilevers, with resonant frequencies of 351.66 kHz (ω2 for detecting) and 177.38 kHz (ω1 for sensing),...
A passive, non-contact piezoelectric microelectromechanical system sensor, aimed to perform monitoring of electricity consumption in DC electrical appliances with current switching, was proposed and demonstrated. A micro-magnet was integrated into the proposed sensor and an appropriate position for locating the micro-magnet was theoretically determined. A prototype piezoelectric sensor was fabricated,...
