【#心脏也能成为充电宝#】#科学家研发微型自供电心脏起搏器#近日，中国科学院大学联合清华大学、 北京大学、阜外医院等单位，为心脏病患者带来了一个重磅消息——他们成功研发出了一种微型心脏起 搏器，能够直接利用心跳给自己供电。科研团队从自然界的"共生"现象中获得灵感，想到了一个巧妙的 办法——让机器成为和人体"共生"的伙伴。相比传统的火柴盒大小的起搏器，这台新型起搏器只有胶囊 大小，可以通过导管经腿部股静脉微创植入患者心脏内，创伤要小得多。别小看这点电量，它已经远远 超过了起搏器长期运行需要的能量门槛。这样，就形成了一个共生循环，心跳让起搏器有了源源不断的 动力，又能反过来给心脏"续命"。（人民网）#热点科普# 转自：大众新闻-大众日报 ...

科研团队从自然界的"共生"现象中获得灵感，想到了一个巧妙的办法——让机器成为和人体"共生"的伙 伴。相比传统的火柴盒大小的起搏器，这台新型起搏器只有胶囊大小，可以通过导管经腿部股静脉微创 植入患者心脏内，创伤要小得多。最不可思议的是，这台起搏器自带"微型发电站"，能够把心脏的每一 次跳动化作40微焦左右的能量。别小看这点电量，它已经远远超过了起搏器长期运行需要的能量门槛。 这样，就形成了一个共生循环，心跳让起搏器有了源源不断的动力，又能反过来给心脏"续命"，可以说 实现了"双向奔赴"。 有没有想过，我们的心脏也可以成为一个"充电宝"？最近，中国科学院大学联合清华大学、北京大学、 阜外医院等单位，为心脏病患者带来了一个重磅消息——他们成功研发出了一种微型心脏起搏器，能够 直接利用心跳给自己供电。 对心脏病患者来说，植入身体里的心脏起搏器就像一位全天候值守的"护卫"，能够时刻稳住心跳节奏。 但这位"护卫"有个致命弱点——电量一旦耗尽就会立刻"罢工"，患者必须重新接受手术，来更换电池， 这就意味着额外的创伤和风险。 目前这项技术已经在动物身上成功应用。在心律失常的猪模型身上，它已经成功自主运行了一个月，一 边靠心跳 ...
