Conductive micro-channel structure
View Patent ↗A conductive micro-channel structure includes a layer having layer edges and an electrode having first and second portions formed in or under the layer. One or more fluid micro-channels are formed in the layer, expose the first portion of the electrode, and extend to a layer edge to form a fluid port. A conductor micro-channel includes a solid conductor in the conductor micro-channel. The solid conductor is electrically conductive, is electrically connected to the second portion of the electrode, and extends from the second portion to a layer edge to form a conductor port.
