Science Alert   May 13, 2022 An international team of researchers (UK, Italy, Norway New Zealand) has developed a bio-photovoltaic energy harvester system using photosynthetic microorganisms on an aluminium anode that can power a microprocessor widely used in Internet of Things applications. The proposed energy harvester has operated the microprocessor for over six months in a domestic environment under ambient light. It is comparable in size to an AA battery, and is built using common, durable, inexpensive, and largely recyclable materials… read more. TECHNICAL ARTICLE
