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 ...

Our hacker [Wil Carver] has sent in his submission for the One Hertz Challenge: Precise Time Ref via 1 Pulse-Per-Second GPS Signal. This GPS Disciplined Oscillator (GPSDO) project uses a Piezo 2940210 ...

Sometimes the need arises for a simple, gated, pulsed alarm. The circuit shown here employs just four components and a piezo sounder and is unlikely to be out-done for simplicity. While it does not ...

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 ...

Appropriately cut quartz crystals can be used as high-quality electromechanical resonators. Their piezoelectric properties (voltage across the crystal deforms it; deforming the crystal generates 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 ...
