Design methodology for the co-design of mechanical structure and interface circuitry of electrodynamic energy harvesters
Final Report Abstract
Energy harvesting enables ambient energy to be converted into electrical energy in order to operate energy-autonomous wireless sensor nodes. This opens up new application possibilities for Industry 4.0 and the Internet of Things, in which many sensors are used decentrally. The research project developed a design methodology for the co-design of mechanics and electronics for electromechanical vibration harvesters. The aim was to create an optimal system that utilizes synergies between mechanics and electronics. Through model-based development, an overall concept of harvester and load adjustment electronics was developed that takes into account parameters such as signal shape, frequency and size. Various modeling approaches were evaluated in order to find an optimal level of abstraction. A compromise between accuracy and computational effort was achieved. A harvester was manufactured and tested to validate the results. An ASIC was implemented, simulated and manufactured, but could not be validated by measurement.
