New sensors will give light touch to robots
Researchers reported about the new type of sensor, which will give light touch to robots. It allows the machines to ‘feel’ surfaces by using electricity and tiny particles. The device will give tactile sensitivity to robot, which is equivalent to human fingers. According to Vivek Maheshwari and Ravi Saraf of the University of Nebraska in Lincoln, the electroluminescent film glowed in response to an applied force. A specialized camera will capture this light and translate into picture, which is as similar to the touching and feeling an object. Now Surgeons can use their sense of touch to find tumors or gallstones. The film is made of alternating layers of gold and semi conducting cadmium-sulfur nano-particles separated by non conducting or dielectric films. These humanoid robots can sense shapes, hardness and manipulate object, which is not possible by vision alone. Via: eWeek
