A team of researchers at The University of Manchester is the first to create a flag that can simultaneously harvest wind and solar power. The flag is made of flexible piezoelectric strips and flexible photovoltaic cells. Piezoelectric strips allow the flag to generate power through movement, while the photovoltaic cells capture the power of the sun.
The goal of this technology is to have a cheap sustainable energy collection solution and have little or no maintenance. Currently the flag is capable of powering small portable electronics that operate in micro-Watt to milli-Watt power range. The researchers hope to develop the technology further so that it can support more power-demanding applications such as charging-stations for mobile devices.
