Nanotube Synthetic Skin |
|||
![]() Nanotube Synthetic Skin Researchers at Stanford University have developed artificial skin incorporating carbon nanotubes. The skin uses spray-on carbon nanotubes, in a liquid suspension, applied to a layer of silicon, which is then stretched to align some of the nanotubes into bundles that resemble tiny springs. These bundles, can be repeatedly stretched without losing their conductivity. By coating both sides of the silicone with these nanotubes, the "skin" becomes both touch and pressure sensitive. The pressure-sensitivity comes from two conductive parallel plates that increase in capacitance as they are squeezed together. The new skin technology is likely to have applications in both robot exteriors and human prostheses.
