Course detail

Energy Harvesting

FSI-RAEAcad. year: 2010/2011

The course “Energy Harvesting” deals with introduction of unique ways of the energy generating from surroundings. Currently remote electronics, low power devices and wireless sensors are powered by batteries. One possibility to overcome energy limitations of batteries or possibly fully substitute batteries is to harvest energy from the environment to power the electronics. The ambient energy is available in the form of radiation, thermal energy and mechanical energy of the environment. The course “Energy Harvesting” is focused on energy harvesting from mechanical energy of vibrations, shocks, deformation, human behaviour etc., and simulation modelling of energy harvesting systems.
