About 10 years ago, researchers in France developed plastics with releasable crosslinks.

大约 10 年前， 法国的研究人员开发了具有可释放交联的塑料。

That curing forms crosslinks among groups of atoms in this plastic.

固化会在塑料的原子团之间形成交联。

Their permanent crosslinks have meant these plastics can't just be melted and reshaped.

它们的永久交联意味着些塑料被熔化和重塑。

Here, groups of atoms say goodbye to their partners as their crosslinks break apart.

在里，原子团在它们的交联断裂时向它们的伙伴说再见。

Then the groups pair up to crosslink with new partners.

然后些小组配对以与新合作伙伴交联。

(Applause) So what we had to do was figure out a way to put a sensor, connected to this crosslinks of the stent that could record that brain activity.

（掌声）所以我们必须想办法放置一个传感器，连接到支架的个交联点上可以记录大脑的活动。
