About this Research Topic
Miniaturized energy harvesting systems, such as piezoelectric energy harvesters, triboelectric energy harvesters, and miniaturized microbial fuel cells, have found great potential applications in emerging fields such as wireless sensor networks, and internet of things applications. Nowadays one of the critical issues for wireless sensor networks and the internet of things development is its power supply. Semiconductor chips in these systems benefit from the scaling effect of miniaturization, while traditional power sources, such as lithium-ion batteries, suffer from lower capacity due to miniaturization, and often require frequent replacement after deployment. As a result, it is critical to develop miniaturized energy harvesting systems which are self-sustainable for these emerging applications.
This Research Topic focuses on the cutting-edge technology of miniaturized self-sustainable energy harvesting systems, such as miniaturized microbial fuel cells, piezoelectric energy harvesters, and triboelectric energy harvesters, as well as novel miniaturized energy harvesting systems based on other technologies. Besides the transducer design, in many cases, the output power from the energy harvesting systems cannot be directly used to power the loads. Power management electronics are necessary in energy harvesting systems. The aim of power management circuits is to improve the performance of miniaturized energy harvesting systems, striving to achieve an output power in the μW to mW range and an output power density in the μW/cm2 to mW/cm2 range, which allows the miniaturized energy harvesting system to be implemented in low power electronics, wireless sensor networks and for internet of things applications.
