(PhysOrg.com) -- Working together, Matthieu Gaudet and Steve Arscott from the University of Lille in France have built a circuit using a phenomenon known as photoelectrowetting, which allows a switch to be turned on by shining a light on it. As the two describe in their paper on the pre-print server arXiv, the circuit is made by using the principle of electrowetting to cause a drop of water to thin resulting in a conducting cantilever to fall towards a second conducting material allowing current to pass through.
