ABSTRACT:
Fluid-based switches and a method for producing the same are disclosed. In one embodiment, the switch comprises first and second mated substrates defining therebetween at least portions of a number of cavities, a plurality of electrodes exposed within one or more of the cavities, a switching fluid that serves to open and close at least a pair of electrodes in response to forces applied to the switching fluid, a surface tension modifier coating at least a portion of the switching fluid, and an actuating fluid, held within one or more of the cavities, that applies the forces to the switching fluid.
