Did you know that, deep in the mammalian ear canal, there’s a naturally occurring battery that scientists have harnessed to power a tiny chip? And then there’s the pacemaker design that’s completely powered by the very heartbeats it seeks to regulate. What each of these technologies shares is the freedom from traditional battery power. Imagine how many other small and integrated devices we could create if we relied on our own bodies for electrical power instead of external batteries.
