The future of surgery may involve robotic devices that are soft and gentle to prevent unwanted damage, yet strong enough to be able to manipulate tissues.
At MIT engineers are leading the way toward that future having developed robots made out of hydrogel and powered by water, that can, among other things, grab and release a live goldfish inside an aquarium. The device isn’t performing appendectomies quite yet, but it’s certainly illuminating what may be possible.
