Can you charge a modern smartphone wirelessly using only a stack of standard batteries? 🔋 We put this viral science "hack" to the test!
While this setup looks like a demonstration of electromagnetic induction (the principle behind wireless charging), the voltage and current output from these few AA/AAA batteries are far too low to power the phone's charging coil and internal circuitry.
The charging animation you see is often a visual trick or an edited effect, as this configuration is highly unlikely to provide a genuine charge to a modern smartphone! Science fact check complete!

日本利用压电瓷砖将人们的脚步转化为电能。这些瓷砖能够捕捉你脚步产生的动能。当你行走时,你的体重和动作会对瓷砖产生压力。瓷砖会轻微弯曲,产生机械应力。瓷砖内部的压电材料会将这种应力转化为电能。
每一步都会产生少量电荷,数百万步加在一起,就能产生足够的电力来驱动 LED 灯、数字显示屏和传感器。
在像涩谷车站这样人流密集的地方,每天大约240万步都在为这个系统做贡献。这些电力可以储存起来或立即使用,从而减少对传统能源的依赖,并支持可持续的城市基础设施。这种方法把日常的动作转化为实用的可再生能源。#日本 #知识 #事实 #你知道吗 #推荐 科技创新 历史 技术 实验
