temperature and pain and pressure, of course, but also the delicate
narcotic of another’s fingers lightly brushing against it. Touch is
what’s between us and everything else, for better or for worseIt should be no surprise to learn that engineers are fascinated by skin and its sensory potential. A new paper published in the IEEE’s Nanotechnology Magazine outlines the concept of “smart skins” and their fabrication using ink-jet printing—a cheap and “green” alternative to conventional electronics manufacturing. The ink: a solution of carbon nanotubes, particles highly desirable for their malleable electrical conductivity and chemical sensitivity.’
