Medical implants 医用植入设备 A sweet idea. 一个甜美的想法。 Researchers are trying to harness glucose-the body s own fuel-to power implantablegadgets such as pacemakers. 研究人员正试图利用葡萄糖-人体自身的燃料-作为像起搏器这样的可植入设备的能源 LIKE any other electrical device, a pacemaker needs a power source. Since the firstpermanent pacemaker was installed in 1958, manufacturers of implantable medical devices have tinkered with many different ways of supplying electricity to their products. Avariety of chemical batteries have been tried, as well as inductive recharging schemes andeven plutonium power cells that convert the heat from radioactive decay into electricity.Plutonium-powered pacemakers still turn up from time to time in mortuaries and hospitals,and a failure to dispose of them properly keeps America s Nuclear Regulatory Commissionbusy handing out citations to unsuspecting hospitals. 和其他所有的电子设备一样，一个起搏器同样需要能源。自从1958年第一个永久起搏器被植入后，可植入医疗设备的制造商就在不断尝试为其产品提供电能的各种方法。尝试了各种化学电池以及感应充电计划，甚至是将放射衰变的热能转换为电能的钚电源单元格。现在，钚电源起搏器还是时不时的出现在停尸房和医院中，并且使得美国核管理委员忙于忙于处罚那些疏于妥善处理钚电源起搏器的医院。 |
