Science View S2014E13 - A High-Sensitivity Sensor - The Sense of Touch

Today we'll be taking a closer look at the sense of touch. This sense allows an experienced metal craftsman to detect a miniscule deformation with his fingertip.

Join us as we explore the high-sensitivity sensor that mankind has acquired over millions of years of evolution - the exquisite sense of touch.
