Fake finger reveals the secrets of touch : Nature News

Experiments with a pressure sensor covered with artificial fingerprints seems to indicate that the ridges amplify vibrations caused by surface roughness, making it possible for deeply-embedded nerve fibers to resolve surface texture. An experiment compared a sensor with and without surface microridges, and discovered that the ridges amplified surface roughness data by more than 100 times. These results could be used to improve the sensitivity of next-generation tactile sensors by coating them with fine surface ridges.

Dust-Size "Crabs" Grab Living Cells in Lab Video

A wirelessly-controlled micro-gripper has been videotaped grasping living cells as a demonstration of what it is capable of. Only now working in a laboratory situation, they hope to eventually have a device available for use in minimally-invasive surgery. The developers caution that a great deal of work still needs to be done so practical implementation is years down the road.
