摘要

1970年，巴黎的外科医生植入了第一个核动力起搏器，在接下来的五年里，至少有1400人接受了这种装置，主要在法国和美国。这些设备的电池包裹在钛中，含有一种放射性同位素（通常约为十分之一克钚-238），可以在不需要维护的情况下运行数十年。这项发明减轻了以前每隔几年就需要手术更换心脏起搏器化学电池的人群的负担。

The Unlikely Revival of Nuclear Batteries: Startups Plan to Put them in Robots, Sensors, and Medical Implants

In 1970, surgeons in paris implanted the first nuclear-powered pacemaker, and over the next five years, at least 1,400 additional people received the devices, mostly in France and the United States. Encased in titanium, the batteries for these devices contained a radioactive isotope—typically about a tenth of a gram of plutonium-238—and could operate for decades without maintenance. The invention provided relief to a population of people who previously needed surgery every few years to change out their pacemaker's chemical battery.
