Rat muscle tissue has been used to power tiny robots, a development that could lead to stimulators that help paralyzed people breathe and “musclebots” that maintain spacecraft by plugging holes from micrometeorites.

MEMS are tiny machines that range in size from a micron—a millionth of a meter—to a millimeter—a thousandth of a meter.

They are created with modified silicon fabrication technology, molding and plating, electro discharge machining and other technologies capable of manufacturing very small devices.

Researchers are interested in using living muscle to power MEMS because…
