'Tree-on-a-chip' device may be used to make small robots move

Engineers have designed a microfluidic device they call a 'tree-on-a-chip', which mimics the pumping mechanism of trees and plants. Like its natural counterparts, the chip operates passively, requiring no moving parts or external pumps. It is able to pump water and sugars through the chip at a steady flow rate for several days.
