A real bit of cyborg hardware highlights the technology’s current limitations.
“MuMuTAs were created by culturing thin muscle sheets and rolling them into cylindrical bundles to optimize contractility while maintaining oxygen diffusion,” Takeuchi explains. “To transition to a dry environment, future developments will need to incorporate artificial nutrient delivery systems and protective scaffolds to maintain tissue viability outside the liquid medium,” Takeuchi says. But perhaps the most obvious issue with using biological muscles in robots remained unresolved: After making gestures and manipulating objects for about 10 minutes, the biohybrid hand got tired.
