Artificial Finger Able to Identify Surface Materials with 90% Accuracy

Video description

A team of researchers at the Chinese Academy of Sciences, has developed an artificial finger that was able to identify certain surface materials with 90% accuracy. In their research published in Science Advances, the scientists describe how they used triboelectric sensors to give their test finger an ability to gain a sense of touch. The finger was created by placing small sensors made of various types of plastic polymers to the tip of a finger-shaped object. The sensors, with electrical properties, were connected to processors. The finger could determine the right materials 98.6% of the time, with a minimum accuracy of 90% for all surfaces. The researchers suggest the technology could be used to test products to ensure they meet manufacturing standards. The Courtesy of Tech Xplore.
