A miniature stretchable pump for the next generation of soft robots

Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts.

Weighing just one gram, the pump is completely silent and consumes very little power, which it gets from a 2 cm by 2 cm circuit that includes a rechargeable battery.

Soft pumps can also be used to circulate liquids in thin flexible tubes embedded in smart clothing, leading to garments that can actively cool or heat different regions of the body.

The soft and stretchable pump is based on the physical mechanism used today to circulate the cooling liquid in systems like supercomputers.
