LED drivers that receive their power from a single cell are receiving a great deal of attention. To generate the high voltage for illuminating a white LED from a low-voltage power supply basically ...

Imperial College is developing an implantable passive blood pressure monitor based around a SAW (surface acoustic wave) oscillator. “In essence, it is an oscillator that you can ping from the outside ...

Sand 9 has launched Piezo-electric MEMS timing device based on its patented Temperature Compensated MEMS Oscillator (TCMO) platform. Sand 9 says the TM651 exceeds the performance of quartz in several ...

How an ultra-tiny, injectable energy-harvesting, temperature-sensing, and data-link system was developed. The use of ultrasound energy to provide both a wireless power source and data link. How a ...

This beeper circuit will generate an car-splitting 110dB from 9V. The setup uses a single 74C14 (CD40106B) CMOS hex inverting Schmitt-trigger IC, which must be used with a piezoelectric device with a ...

All sorts of counterintuitive behavior happens with regularity in the quantum realm, but very little of that bleeds over into the world of classical mechanics that the human senses occupy. We can ...

The sub-millimeter cube, which measures temperature, merges CMOS and piezo for power, and there's an ultrasound link. How an ultra-tiny, injectable energy-harvesting, temperature-sensing and data-link ...
