Energy harvester and sensing for safety in autonomous cars

The overall goal of the project is to develop a new concept of miniaturized energy harvester needed for wireless sensor systems and digitization, with a focus on sensing the safety of passengers for driverless cars. The 5-year project is a collaboration between RISE, Chalmers, Autoliv and ReVibe Energy AB.

The digitalisation of modern industry is rapidly increasing the need for sensors and sensor systems, which require energy supply and face sustainability challenges. We focus on developing important enabling energy solutions by harvesting energy from surrounding sources, which is the most promising technology for smart self-powered sensor systems.

The biggest challenge in developing a miniaturized energy harvester for industrial application is the very low frequencies and amplitude movements / vibrations that are available. Combining piezoelectric and electromagnetic transducers into a hybrid energy harvester working in the non-linear regime will solve several problems associated with the availablilty and efficiency of energy sources.
