Touch can be a subtle sense, but it communicates quickly
whether something in our hands is slipping, for example, so we can tighten our
grip. For the first time, scientists report the development of a stretchable
“electronic skin” closely modeled after our own that can detect not just
pressure, but also what direction it’s coming from. The study on the advance,
which could have applications for prosthetics and robotics, appears in the
journal ACS Nano.
