Highly Isolated Power Source

Have you ever had a need for an isolated power source floating at high voltage? If you’ve ever considered a battery, but then quickly rejected that thought because you would need to replace it periodically, here’s a technique that doesn’t require wires, transformer or any other traditional approach.

Advanced Cerametrics has introduced Extreme Life Span Micro Power Supplies that harvest energy from ambient sources of vibration energy to power wireless sensors and other devices…forever. It uses piezoelectrics to generate electricity. For more information see http://www.advancedcerametrics.com/pages/energy_harvesting/. You can also build your own, using piezoelectric materials.
