Active substance: Pump prototype
What this could lead to: If successful, this pump could make prosthetic limbs more comfortable and easier to use for people with amputations.
What could go wrong: This was a small, early lab study with only 12 participants, so results may not apply to everyone. The pump may not work as well in daily life.
