US 10,926,523 B2 · Performance enhancement of sensors through surface processing

Abstract

Techniques for modifying surfaces of electrodes are provided. An electrode surface can be processed by applying an abrasive material or chemical solution to or against the surface to modify the surface to reduce the amount of roughness on, and/or alter the shape of, the surface. The shape of the surface can be altered by rounding or doming the surface. During surface processing, flexible or compressible support material can be applied to the back of an abrasive material, such as sandpaper, to desirably distribute pressure from the support material to the sandpaper and/or mold the shape of the sandpaper to facilitate maintaining desirable contact by the sandpaper on electrode surfaces. With regard to a flexible circuit board on which electrodes are formed, a vacuum chuck component or a temporary abrasive can be used to hold the circuit board in a flat and stationary position during surface processing.

Dependent claims

A method, comprising:

forming an electrode;
and
modifying a surface of the electrode to reduce an amount of roughness of the surface of the electrode and alter a shape of the surface, wherein the amount of roughness is based at least in part on a number or a size of protrusions on the surface of the electrode, and wherein the altering of the shape of the surface of the electrode comprises altering the shape of the surface of the electrode from a flat or substantially flat shape to a rounded shape, comprising rounding an edge portion of the surface, on at least a first side of the surface and a second side of the surface that is perpendicular to the first side of the surface.

A system, comprising:

a surface processor component configured to modify a surface of an electrode to reduce an amount of roughness of the surface of the electrode and change a shape of the surface, wherein the amount of roughness is based at least in part on a number or a size of protrusions on the surface of the electrode, and wherein the changing of the shape of the surface comprises changing the shape of the surface of the electrode from a flat or substantially flat shape to a rounded shape, comprising rounding an edge of the surface, on at least a first side of the surface and a second side of the surface that is perpendicular to the first side of the surface;
and
