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 ...

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 ...

Texas Instruments has removed the need for external timing crystals by developing a technique for building high-grade thin film piezoelectric bulk acoustic wave (BAW) resonators within the ...

Quartz is used in watches as it acts as a piezoelectric oscillator. Quartz is used in watches as it acts as a piezoelectric oscillator. As a potential difference is applied across quartz, stress is ...

In recent years, with the growing concerns over environmental protection and human health, environment-friendly materials have received increasing attention, and for decades researchers have been ...

Abstract: Quartz crystals are mechanical resonators with piezoelectric properties. The piezoelectric properties (electric potential across the crystal is proportional to mechanical deformation) allow ...

The Vibrating Probe is a device which detects current densities by vibrating a probe about a micron in amplitude, using a piezo-electric bender/oscillator. The probe output is fed into a lock-in ...
