China’s ‘electric eel’ sensor allows robots to feel an object without touching it

Electric eels hunt in pitch-black, murky waters by generating electric fields around their bodies. Now, Chinese scientists have mimicked this natural radar, giving robots the ability to “feel” objects without making physical contact. “We want the machine to sense an approaching target – distinguish its material and surface condition – before any physical contact,” said Zhang Weiqiang, a professor at Xidian University, in a video interview last week. Their work was published last month in the...
