Boston MA (SPX) Aug 16, 2024

A tiny battery designed by MIT engineers could enable the deployment of cell-sized, autonomous robots for drug delivery within in the human body, as well as other applications such as locating leaks in gas pipelines. The new battery, which is 0.1 millimeters long and 0.002 millimeters thick - roughly the thickness of a human hair - can capture oxygen from air and use it to oxidize zinc, cr
