With Energy Harvesting technologies, sensors for detecting wear out or damage in machines (condition monitoring) can be supplied with energy independently. Our technologies offer enormous advantages over conventional power supplies with batteries, especially in hard-to-reach locations or where data is frequently collected. Existing vibrations and temperature differences at production plants can therefore be used sensibly for the energy generation. Thus, machine conditions can be monitored and analyzed permanently and maintenance-free.
Energy Harvesting for smart building
Even in supply rooms, important environmental data such as temperature, air conditions, hazardous gases etc. can be easily determined with IoT sensors and transmitted via wireless networks. Energy Harvesting technologies from Fraunhofer IIS ensure a self-sufficient energy supply in such applications. With permanent condition monitoring, you can extend the service life of building systems and avoid costly repairs and early new acquisitions. By using a self-sufficient energy source, you can achieve this without major installation and maintenance costs.
The special feature of our Energy Harvesting technology
Fraunhofer IIS is focused on the development of highly efficient power management systems and power supplies as well as complete microsystems. Even small temperature differences or movements are sufficient to power wireless sensors and radio transmitters. The processing of smallest currents (less than 3µA) and voltages (less than 20 mV) is major competence here. The voltage converters developed at Fraunhofer IIS enable a high degree of efficiency to be achieved even with the smallest temperature differences or movements. Thus, more than 200 microwatts of electrical power can be generated at a temperature difference of just 2 Kelvin. The smallest vibrations of just 60 Hz provide an energy yield of 1.2 milliwatts. The developed Maximum Power Point Tracker effectively controls the regulation circuits of the voltage converters for automatic impedance matching and thus guarantees a maximum power output in various operating situations. The optimum thermal, mechanical and electrical design of all system components enables highly efficient applications to be implemented in a minimum of space, thus clearly distinguishing them from the state-of-the-art.
