Energy harvesting applications are finding their way into many remote monitoring applications where utility power is not available. New developments in ultralow power microcontrollers with their high level of integration are enabling monitoring systems which draw sub milliwatts of power. Various energy sources that were not useful as power sources for electronic sensors can now be used. The energy harvesting system must be highly efficient and present minimal loading effect on the energy source and the output storage elements when in their "sleep" mode.
