Abstract
An electrowetting cell includes a substrate that includes a well filled with at least one fluid an external contact surface. The substrate is formed of ceramic or fiberglass mesh infused with resin. A control channel electrode connection pad and a common electrode connection pad are on the external contact surface. A first plate is coupled to the substrate to seal a first end of the well. A second plate is coupled to the substrate to seal a second end of the well. The electrowetting cell further includes a control channel electrode on the substrate configured to control a shape of the at least one fluid via an electric field, a common electrode, a control channel electrode interconnect connected to the control channel electrode and the control channel electrode connection pad, and a common electrode interconnect connected to the common electrode and the common electrode connection pad.
