So, I’m reading this article from 2016, particularly these bits:
In the summer of last year, Amal Graafstra had a question: Could a solar cell under his skin get enough light to power other devices he may one day implant in his body? To find out, he bought a $5 solar-powered calculator from Wal-Mart, pulled out the 1-by-4-centimeter solar cell, cut open his arm, placed the cell under his skin and sewed it back up. By comparing the power output from the cell below his skin versus its output above his skin, he could tell that the cell was indeed able to gather light and put out power. It worked, and Graafstra cut out the little cell.
“I now know for this particular spot in my arm the difference in a solar panel’s performance above the skin and below,” he said.
Two questions spring to mind:
- How much power did the cell get under your skin versus in the open? Was it even usable if it wasn’t summer solstice at noon?
- Wouldn’t it have been easier to try it under a patch of pig skin? I’m beginning to think you enjoy cutting yourself open
