Chinese scientists develop an implantable battery that runs off the oxygen in your blood
<p>From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and dampen pain. But batteries eventually run low and require invasive surgeries to replace. To address these challenges, researchers in China devised an implantable battery that runs on o...

Put them in my hands so I can just charge my phone by holding it.
Also, if someone has a heart attack and needs defibrillation, I'll have it covered.
I like your thinking but I doubt it will work in its current state.
The researchers then implanted the battery under the skin on the backs of rats and measured its electricity output. Two weeks later, they found that the battery can produce stable voltages between 1.3 V and 1.4 V, with a maximum power density of 2.6 µW/cm2. Although the output is insufficient to power medical devices, the design shows that harnessing oxygen in the body for energy is possible.
2.6 µW/cm2.
Harvesting the energy from vibrations would probably generate more ( ͡° ͜ʖ ͡°)
Yeah but who's gonna masturbate the mice?
2.6 microwatts per cm^2 of what? Surface area of anode/cathode in the battery? Summary does not say.
