US scientists make ultra-thin pacemaker that's powered by light | Inspired by photovoltaic cells, the technology could also be used for neuromodulation and treating diseases like Parkinson's.
Using two layers of P-type silicon, researchers made an ultra thin membrane that converts light into electric charges to adjust the heart's beat.
This principle is used in cardiac resynchronization therapy, where different heart parts are brought back into sync by delivering precisely timed electrical charges. When required, the optic fiber can light up in precise patterns, turning into electric charges to regulate the heart. Over time, the device dissolves into a compound called silicic acid, which is nontoxic and removed from the body.
