An efficient Piezoelectric energy-harvesting interface Circuit

Energy harvesting is an emerging technology with applications to handheld, portable, and implantable electronics. Harvesting ambient vibration energy through piezoelectric (PE) means is a popular energy-harvesting technique that can potentially supply 10’s-100’s of μW of available power [1]. One of the limitations of existing PE-harvesters is in their interface circuitry. Commonly used full-bri...
