Send us a textTiny batteries for tiny robots that could deliver drugs inside our bodies Engineers at MIT have developed a miniature battery that can power cell-sized, autonomous robots for drug delivery within the human body, as well as for other purposes such as detecting leaks in gas pipelines. The batteries measure 0.1 mm in length and 0.002mm in thickness each - that’s about the same thickness as a human hair. The battery captures oxygen from the air and uses it to oxidize zinc, generating a current with a potential of up to 1 volt. This output is sufficient to power small circuits, sensors, or actuators. Professor Michael Strano, who led the team behind the work, is on the show.
