A touch sensor having conductive circuits on both surfaces of a substrate is fabricated by including UV-blocking material into the substrate or depositing UV-blocking layer on the substrate. This can be used for fabricating sensors having transparent conductor circuits, or having metallic circuits, which are opaque to visible light. Photoresist is applied to both surfaces of the substrate and patterns are transferred to the photoresist by exposure to UV radiation. The UV-blocking layer prevents UV-radiation applied to one side from exposing the opposite side. If desired, both photoresist layers may be exposed simultaneously by splitting one UV beam.

A method of agglomerating nanoparticles to form larger agglomerates is shown. The nanoparticles are mixed with a resin to form a first mixture (803) of agglomerates, having sizes over a range that includes agglomerates considered to be too large, suspended in the resin. A bead milling cylinder (802) produces a second mixture (808) with fewer large agglomerates. A filter (1001) removes the remaining large agglomerates. The resulting mill base is cut with a solvent before deployment.

Systems and methods that provide audio feedback in response to gesture validity can provide a more intuitive interface that can train users to correctly complete gestures. Moreover, systems and methods that provide line-specific audio feedback can provide more specific feedback that can allow a user to better understand what sensing line is being contacted. The systems and methods can further include basing the audio feedback based at least in part on obtained activity data, such that invalid and valid feedbacks can provide different sounds dependent on the determined activity state.
