Replacement of power supplies of implanted medical devices is usually associated with surgical intervention. Solving this long-standing problem will help technology developed by a group of Swiss scientists at the University Hospital of the University of Berne under the leadership of Lucas Bereuter.

They suggested using subcutaneous medical implants in the form of solar cells, which after installation no longer need to be recharged and replaced. As prototypes, the researchers developed 10 solar wrist gauges measuring 3.6 square meters. see To model the properties of the skin, their optical filters were covered with a special film.

To test wearable devices (weekly for each season) 32 volunteers agreed. The results of the study look quite encouraging: even after a long period of operation, the power source produced 12 microwatts. To feed a conventional pacemaker, enough from 5 to 10 microwatts.

Lucas Bereuter believes that this “solar” technology can easily be used for other portable electronic devices.
