Story summary

Chinese scientists at Xidian University built a robot sensor that detects objects without contact, copying electric eels.
Professor Zhang Weiqiang said the sensor lets a machine sense a target and identify its material and surface before touch.
When an object approaches, the charged fluoropolymer reads field disturbances and infers conductivity, dielectric properties and shape, forming an invisible spider-web-like electric field.
