Ultra Low Power Meets Energy Harvesting
Macro-scale energy harvesting technologies in the form of windmills, watermills and passive solar power systems have been around for centuries. Now, as designers seek to cut the cords, they turn to microenergy harvesting systems that can scavenge milliwatts from solar, vibrational, thermal and biological sources. However, understanding ultra-low power from the sourcing side brings challenges as harvested power derived from ambient sources tends to be unregulated, intermittent and small.
