Scaling up production may be a challenge, though, as it is hard to farm spider silk in large amounts. “It looks like something you could do in your kitchen at home.” “What’s really astonishing is that the method of incorporation of the carbon nanotubes is incredibly simple,” she says. There are other methods of combining carbon nanotubes with biological materials, she adds, but they usually require expensive equipment and chemicals, and the end result is not mouldable. “These results open new opportunities in moulding and shaping actuators or sensors, where you could potentially think about different geometries or forms,” says bioengineer Kimberly Hamad-Schifferli of the Massachusetts Institute of Technology. By contrast, the silk-based version can be wrapped around irregularly shaped objects, such as wrists or fingers, without losing sensitivity. The carbon-silk combination is also sensitive enough to detect the electrical signals from a heart pulse.Ĭommercially available pulse-detectors are often made of rigid materials. The wire grips the contact area without having to use a conducting paste or solder.” “We simply wind the coated fibre around the contact area and, by controlling the humidity, we can let it shrink. As the silk naturally expands and contracts when exposed to different humidity levels, the new, flexible hybrid can be easily manipulated to create good electrical contact for wiring. This composite is three times tougher than spider silk alone. When the material dried out, the silk was coated with a thin layer of nanotubes. He polarised a powder of carbon nanotubes so that the tubes would stick to the naturally charged silk, then mixed the materials with a few drops of water and pressed them between two sheets of Teflon. To create a conductive but less rigid silk, Eden Steven at Florida State University in Tallahassee collected bundles of silk from a species of golden orb-weaver spider.
