Fun in the sun: Pacemakers may soon be solar powered

Pacemakers that are powered by traditional batteries need to be replaced once every few years. However, solar-powered pacemakers carry the potential to last forever.

Researchers say that energy from sunlight may be a possible, according to a study published in the international journal Annals of Biomedical Engineering.

The repated procedure of replacing or recharging current cardiac pacemakers is costly and potentially dangerous to the health of the patient. The study suggests that solar is a promising alternative. Multiple groups of biological scientists have created prototypes that are powered by solar cells placed underneath the skin.
