Energy harvesting flexible regenerative power source for wearable devices

We present the design, development and testing of an electronics module to harvest, regulate and store vibrational energy. The module includes a flexible rechargeable battery to store the harvested vibrational energy generated from normal human physical motion. The proposed regenerative power source is examined by integrating with a Galvanic Skin Response (GSR) sensor suitable for continuous long term measurement of stress and fatigue levels of personnel working in physically demanding and extreme work conditions.
