E-skin outperforms human sensory nervous system

n-neuralskin1Researchers at the National University of Singapore have demonstrated a novel type of signal architecture that could make robotic and prosthetic electronic skins much faster and more robust than today’s sequentially sampled tactile sensor arrays.

Instead of relying on time-divisional multiple access to reconstruct a two-dimensional map of pressure / temperature distribution, the researchers chose an event-based signal architecture, where sensors asynchronously transmit data upon value changes.

This is similar to the skin’s biological mechanoreceptors, their source of inspiration, which can fire spike signals asynchronously and form very precise spatiotemporal patterns that reach the brain at a constant latency for sensory interpretation.

BlueMan, the show you need to see!

BlueMan, the show is an absurd and wondrous blend of music, painting, science and technology, as the Blue Men silently engage in a variety of set pieces that run the gamut from primitive and childlike to witty and sophisticated: absolutely fantastic!

History

Blue Man Group grew out of a collaboration between three close friends, Chris Wink, Matt Goldman and Phil Stanton, on Manhattan’s Lower East Side in 1987.

Its first public appearance was a celebration of the end of the 1980s. The three men wore blue masks and led a street procession that included the burning of a Rambo doll and a piece of the Berlin Wall.

MTV’s Kurt Loder, who covered the event, drew attention to the strange Blue Men—and what began as creative “disturbances” on the streets of the city became a series of small shows at downtown clubs, and eventually a full performance at the Astor Place Theatre in 1991.

In July 2017, Blue Man Group was bought by Cirque du Soleil, who announced that they would expand the concept.
