Exhaust systems have changed dramatically over the years, from the simple single-muffler systems from cars of the '50s and '60s, to the active exhaust systems from select late model cars like the 2025 ...

Researchers have developed a novel type of nanomechanical resonator that combines two important features: high mechanical quality and piezoelectricity. This development could open doors to new ...

Resonators are devices that exhibit resonance, a phenomenon where a system oscillates with greater amplitude at specific frequencies. In the context of nanotechnology, resonators are nanoscale ...

Using a standard CMOS process, researchers have combined acoustic MEMS and other technology to create a >10-GHz on-chip resonator function for filters and VCOs. How standard CMOS process can be used ...
