Tiny Robots Powered by Living Muscle Cells

Posted by CmdrTaco on from the robots-doing-laps dept.

voma writes "Tiny robots powered by living muscle have been created by scientists at the University of California, Los Angeles. The devices were formed by "growing" rat cells on microscopic silicon chips, the researchers report in the journal Nature Materials. Less than a millimetre long, the miniscule robots can move themselves without any external source of power. Muscles like these could be used in a host of microscopic devices - even to drive miniature electrical generators to power computer chips."

    I'm not sure I really see a bad side to this. It's not like we're talking about machines with sentience here, just machines that are powered by muscle. I would think this kind of technology could have possible applications in making more natural-feeling prosthetics, which would be of great use to society. Just think, people could have prosthetic limbs connected directly to their own muscles, for totally natural movement.

    Or we could just make an army of Robocops or something. Six of one, half dozen of the other really.

    Won't the cells eventually die?!

    The cells DO need a source of power: ATP. That's our input. The desired output is electrical energy. 1. ATP 2. -> mechanical energy 3. -> electrical energy I admit, the cool factor is there, but why can't we just use chemical reactions to extract the raw energy from ATP's chemical bonds?
