At its core lies a hydrogel with tunable mechanical properties and a microbial fuel cell, and the hydrogel is capable of being modified thanks to microscale patterning of PEI in order to pave the way for adhesion of myotubes. In the words of the creative team behind the Cyberplasm, “Additionally, mechanical properties of the hydrogel will be tuned via cross-linking to allow maximum motile propulsion of myotubes. The force that myotubes exert on the hydrogel will be assessed by the displacement of embedded fluorescent beads followed by subsequent finite element analysis. We plan to develop a new microbial fuel cell technology to power Cyberplasm electronics.” It would be great to read about a real life application of Cyberplasm, but it is pretty much geeky stuff at the moment.
