Bioengineering: using cells instead of motors

By | November 16, 2012
This is fascinating: movement of artificial bots powered by muscle cells on hydrogel. Strangely zerg-like, but it would seem like a viable energy option that could result in smaller machines with larger tensile strengths. And less likely for implantation rejection. 

These bots were made for walking: Cells power biological machines
They’re soft, biocompatible, about 7 millimeters long – and, incredibly, able to walk by themselves. Miniature ‘bio-bots’ developed at the University of Illinois are making tracks in synthetic biology…
