Selected problems of power sources for wireless sensors networks [instrumentation notes]

The issue of using renewable energy sources to generate electrical power for wireless sensor networks has been the subject of extensive research for at least a decade. The main reason for the dynamic development of this research was the need to supply operating power for wireless sensor networks deployed in areas without access to the electrical grid. Power required to supply each node of the network varies from tens of milliWatts to tens of Watts. This allows you to search for customized solutions in a wide range of phenomena.
