The Water Transistor

As part of our work on an EPSRC program grant on Supercritical Fluid Electrodeposition we have developed a water analogue of a Field Effect Transistor. In this analogue the channel consists of a ballon through which water can flow inside a sealed chamber filled with water which can be used to apply pressure to the balloon causing it to collapse reducing and finally cutting off the flow of water through it. The action is shown in the pictures below.
