An easy and efficient power generator with ultrahigh voltage for lighting, charging and self-powered systems

Can you imagine that when you slide on the polymer plate with your hands, the generated electromagnetic field can drive 28-watt fluorescent tube lamps and can even charge the mobile phone? The progress of science and technology subverts traditional cognition. Here, an easy and efficient power generator (EEPG) with ultrahigh voltage is invented, which can light up 28-watt fluorescent tube lamps. The average output voltage and current of planar EEPG can reach up to nearly 5000 V and 116 μA, respectively. Not only can it be used for lighting, but also for charging, and even for mobile phones. The rotary EEPG can be used to harvest wind energy and tidal energy, which overcomes the shortcomings of traditional electromagnetic wind power generation working only when the wind speed is greater than 5 m/s. In addition, the EEPG power generator can be utilized as a footswitch and trajectory tracking tool. This is likely to become an easy and effective method of power generation in the world. It can be expected that mobile phones can be charged by just rubbing their backs. Collecting the green wind energy more easily and efficiently will be truly realized.
