  "account": "Chinese scientists have developed a sensor inspired by the electric eel, allowing robots to detect objects without physical contact. The innovative technology, published in the peer-reviewed journal Advanced Materials, harnesses the eel's natural radar system to sense an approaching target, distinguish its material and surface condition, and gather information before any physical contact occurs. The sensor, made of a specially treated fluoropolymer, functions like a static battery, creating a steady electric field around it. When an object approaches, the sensor detects changes in the field, enabling it to infer the object's electrical conductivity, dielectric properties, and geometric shape. Remarkably, the sensor can detect movements as small as 50 micrometres, producing a voltage change of about one volt, even after over ten thousand cycles in the lab with stable signal quality. Its versatility lies in the fact that it does not rely on lighting conditions and can sense various materials, including metals, plastics, glass, and wood. Potential applications range from robot manufacturing and equipment inspection to human-robot interaction, non-contact detection for coating inspection or proximity warning, and industrial non-destructive testing. The sensor could enhance safety measures in aerospace scenarios, such as space robot operations, equipment monitoring outside spacecraft, or on-orbit maintenance by robotic arms. However, the current version requires close proximity to the object and further research is needed to extend its range and improve its accuracy in complex environments.",
  "summary": "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…",
