We now take a conductive ink and spray-coat that ink onto these pouches, and then we inject them with oil.

然后把导电油墨喷涂在小格子上，再注入油。

After having done this, we have a conductive ink that acts like a flexible electrode that squeezes these liquid-filled pouches when a voltage is applied.

做完这几步以后，导电油墨就会变成活动的电极，通电后挤压这些充满液体的小格子。

The current they generate is thanks to cyanobacteria, a kind of aquatic bacteria, which the researchers 3D-printed onto plain old button mushroom caps, along with a conductive graphene ink.

它们产生的电流要归功于蓝藻，一种水生细菌，研究人员将其 3D 打印到普通的旧纽扣蘑菇帽上，以及导电石墨烯墨水。
