Smart Electric Fencing Technology — Protect Crops Without Harming Wildlife ⚡🌾

ㅤz!xuㅤ모s1m on Instagram: "日本利用压电瓷砖将脚步转化为电能。这些瓷砖捕捉来自你脚步的动能。当你行走时,你的重量和动作会对瓷砖产生压力。瓷砖会轻微弯曲,从而产生机械应力。瓷砖内部的压电材料将这种应力转化为电能。每一步都会产生少量电荷,而数百万步结合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。在像涩谷车站这样繁忙的地方,每天大约有240万个脚步为这一系统作出贡献。这些电能可以被储存或立即使用,从而减少对传统电力来源的依赖,并支持可持续的城市基础设施。这种方法将日常运动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 #热门"
