Cats' whiskers inspire nanotube sensors

Researchers have created tactile sensors from composite films of carbon nanotubes and silver nanoparticles that are claimed to be similar to whiskers of cats and rats.

These so-called e-whiskers, developed by researchers at Berkeley Lab and the University of California (UC) Berkeley, are said to respond to pressure as slight as a single Pascal. Potential applications include giving robots new abilities to manoeuvre within their surrounding environment
