New Tactile Sensor for Robots

Posted 9 Jun 2006 at 18:36 UTC by steve Share This

Several readers submitted links to a CNN story and BBC story about a new tactile sensor that is so sensitive it can read the text on a coin by touch. The skin-like sensor technology was developed by Ravi Saraf and Vivek Maheshwari of the University of Nebraska at Lincoln Mesoscale Engineering Lab. The Electronic Skin uses tunneling phenomena within a nanodevice to convert pressure into light and current. They claim it provides a 100 fold improvement in spatial resolution over similar existing sensors and can sense texture at a level comparable to the human finger. The sensor is being hailed as an important advance in robotics because of its relatively simple construction and high resolution.
