Summary In this paper, we propose a new energy scavenging system for powering bio‐implantable devices. Different available energy sources and micro‐generators are examined. The operation of electrostatic generators will be examined in detail, and their design issues are discussed. The proposed generator is analyzed, and a closed form formula is developed for the capacitor voltages. Also, an equation is obtained for the output power for the proposed circuit. It will be shown that the diaphragm muscle in conjunction with the electrostatic micro‐generator can be used to extract energy from human body. The diaphragm muscle has a continuous movement with a relatively fixed frequency. There is enough space around this muscle to place the micro‐generator. Using the proposed system, it will be shown that it is possible to produce 230 mW power in a 125 mm 3 volume from the diaphragm muscle. Copyright © 2017 John Wiley & Sons, Ltd.
