Can you imagine that when you slide gently on an acrylic board with hand, hundreds of LEDs under the board will be lit up! Here we have found that all matters under forces can generate electromagnetic energy, even under a tiny force like wind blow. When a polytetrafluoroethylene sheet is tapped by a hand, the generated electromagnetic field can drive three light boards directly, producing a high output voltage of 3678 V. Amazingly, there was an electrical signal when the wind blew onto a matter such as flower, water, wood, polymethyl methacrylate, paper, stone, ceramic etc. There is an optimal matching state between the substance and the force to reach the maximum electrical output. Finding the best matter and the best collision state of it has significant impacted on the development of new energy and nuclear energy. According to these discoveries, the simplest and the most efficient power generation devices and self-powered systems were designed for collecting electromagnetic energy. The power generation bucket can be easily used to collect energy in the ocean. The power generation stone, and the power generation road can supply for streetlamps, traffic lights, electronic advertising boards, and distributed sensors, etc. These discoveries reported here are expected to have profound impacts on a broad range of applications.
