Introducing a miniscule voltage to an electrode below a lever causes it to bend forwards until it makes contact. Thanks to intermolecular forces on this scale, once flipped, a lever will also maintain its position, even when the voltage is switched off. The trick can be reversed by applying voltage to an electrode on the other side of the lever. And the state of each switch flips can be sensed easily by the electrodes themselves.Does anyone remember articles about how gecko's stick to all sorts of surfaces? Sounds like the same thing. I know there's a joke in there somewhere. It's just not coming to me.
