A revolutionary new hybrid energy harvesting system that generates electricity from either heat or light using a single devicehas been developed by Fujitsu Laboratories Ltd.
Fujitsu Laboratories developed an organic material that is suitable for a generator in both photovoltaic and thermoelectric modes, enabling energy to be generated via solar power, and by heat.
The material can produce power from even indoor lighting in photovoltaic mode, and from heat in thermoelectric mode. If either the ambient light or heat is not sufficient to power the sensor on their own, the technology could draw on both sources simultaneously.
The future applications of this innovative technology are wide-spread, and is set to significantly contribute to medical science and medical instrument applications.
The technology could be used in sensors that monitor conditions such as body temperature, blood pressure, and heart rate - without any wiring or batteries required. Additionally, the technology could be applied in environmental sensing in remote areas for weather forecasting, where financial or logistical challenges exist in replacing batteries or running mains grid power.
