美媒:科学家发明可穿戴发电机 利用尿液供电

  美媒称,日前,一双嵌入了微生物燃料电池(MFC)的袜子成功为一台无线发射器提供了动力,并向一台个人电脑发射了信号。这种MFC以尿液为燃料,靠穿戴者行走带动循环。这是首个依靠基于MFC技术的可穿戴发电机提供动力的自给式发电系统。

  据美国每日科学网站12月11日报道,有关这项研究成果的科技论文发表在美国《生物灵感和仿生学》双月刊上。

  论文称,这项试验是由英国西英格兰大学布里斯托尔生物能源中心的扬尼斯·耶罗普洛斯教授带领的。

  报道称,袜子中嵌入的柔软MFC以新鲜尿液为燃料,依靠穿戴者的行走来发电。通常来讲,续流MFC依靠一台主电动泵来让尿液在电池中循环,不过本项试验完全依靠的是人体运动。该试验使用的手动泵类似于简单的鱼循环系统,行走动作可以使尿液在MFC中循环并发电。安装在脚后跟下的软管可以借由行走动作确保频繁的液体推挽。这一可穿戴MFC系统成功地为一块无线传输板供电,使其每两分钟向由个人电脑控制的接收模块发射一条信息。

  耶罗普洛斯说:“我们此前曾用以尿液为燃料的MFC为一部手机供电,这次想看一下我们是否能用可穿戴技术复制这一成功。我们同样想让这一系统做到完全自给,仅靠人力供电——尿液作为燃料、脚部运动作为泵。”
