Powering medical implants with solar cells
The notion of using solar cells placed under the skin to continuously recharge implanted electronic medical devices is a viable one. Swiss researchers have found that a 3.6-square-centimetre solar cell is all that is needed to generate enough power during winter and summer seasons to power a typical pacemaker.
The study is the first to provide real-life data about the potential of using solar cells to power devices such as pacemakers and deep brain stimulators. According to lead author Lukas Bereuter of Bern University Hospital and University of Bern in Switzerland, wearing power-generating solar cells under the skin can one day save patients the discomfort of having to continuously undergo procedures to change the batteries of such life-saving devices.
