CHOOSING A MICROCONTROLLER FOR ENERGY HARVESTING APPLICATIONS

摘要

Energy harvesting has been a topic of interest for engineers for some time. Recent advances have now made this technology a practical reality: the time is ripe for its introduction across a wider market One reason for this increased practical adoption is the advancing sophistication in energy harvesting devices themselves. Photovoltaic principles allow the generation of around 100mW/cm~2, thermal techniques can achieve up to 10mW/cm~2, while vibration can generate up to 1 mW/cm.Although these figures represent significant advances over previous generations of technology, they are still by no means generous. A self-sufficient system therefore needs to store generated energy with low losses, and use active components that work extremely energy efficiently.
