And the other thing means if it's going to be long term, then probably it has to be implantable and that means all of the heart has to be implantable.

另一个问题是如果它要长期工作,就需要植入体内,就是说人工心脏所有部件都是可植入的

Imagine how much power it takes to drive an artificial heart, so you've got to have a battery or some way of generating power continuously to operate that and that makes it difficult to think about implantable and so that's a really good example of Biomedical Engineering.

驱动人工心脏所需要的能量是难以想像的,所以需要电池或者是某种持续发电装置,来给人工心脏提供能量,这就增加了人工心脏的植入难度,这是很好的生物医学工程的例子
