Chinese scientists have developed a robot sensor inspired by electric eels that uses an electric field to detect and identify materials without physical contact.
A team at Xidian University in China is developing technology to transmit solar power from space to Earth. They are testing a system using mirrors, solar panels, and microwave transmitters to send electricity over 100 meters, with a long-term goal of 36,000 km.
China has successfully tested a system capable of beaming microwave power to multiple moving targets simultaneously, including a drone. Developed at Xidian University, the system transmitted 1,180 watts over 100 meters with precise beam control and achieved a 20.8% efficiency.
