I’ve noticed a few articles in the last week about DARPA planning to implant microchips in soldiers, which reminded me that I had read something about the topic in Wired a couple years ago. From that Katie Drummond piece:

“Editing DNA could have widespread implications, but Darpa seems most interested in two: microchip implants that restore senses and movement in traumatic injury patients, and the ongoing Darpa goal of boosting troop performance in the field: On the other end of the size scale, a primary goal is to apply microsystem techniques to soldier-protective biomedical systems. One example is an in-canal hearing protection device that will provide enhanced hearing capabilities in some settings, but be able to instantly muffle loud sounds of weapons fire. This one example will improve inter-personnel communications and at the same time drastically reduce the incidence of hearing loss in combat situations. For these examples and many more, the goal is to bring exceptionally potent technical approaches to bear on biological and biomedical applications where their capabilities will be significant force multipliers for the DoD.”
