Vibrational energy harvesting is an appealing power source for self-powered sensors, especially in recent trend of internet-of-things (IoT). Pervious studies had focused on extracting the vibrational energy with very few implementing an efficient load interface. This article describes an energy extraction mechanism for electrostatic MEMS vibration energy harvesting systems. An autonomous load interface extracting energy in multiple energy-shot transfers is proposed. Moreover, a CMOS implementation of the load interface is presented.
