In a method of manufacturing a highly stretchable three-dimensional (3D) percolated conductive nano-network structure, a 3D nano-structured porous elastomer including patterns distributed in a periodic network is formed. A surface of the 3D nano-structured porous elastomer is changed to a hydrophilic state. A polymeric material is conformally adhered on the surface of the 3D nano-structured porous elastomer. The surface of the 3D nano-structured porous elastomer is wet by infiltrating a conductive solution in which a conductive material is dispersed. A 3D percolated conductive nano-network coupled with the 3D nano-structured porous elastomer is formed by evaporating a solvent of the conductive solution and removing the polymeric material.

An object of the present invention is to provide an electrically conductive paste and a sintered body thereof having a low electric resistance value and excellent electrical conductivity when made into a sintered body. An electrically conductive paste comprising: a flake-like silver powder having a median diameter D50 of 15 μm or less; a silver powder having a median diameter D50 of 25 μm or more; and a solvent, wherein the content of the flake-like silver powder is 15 to 70 parts by mass and the content of the silver powder having a median diameter D50 of 25 μm or more is 30 to 85 parts by mass based on 100 parts by mass in total of the flake-like silver powder and the silver powder having a median diameter D50 of 25 μm or more.

A sensor device includes an emitter configured to emit radiation a detector configured to detect radiation reflected from an object and a cover having an interior surface facing the emitter or detector and allowing the radiation to pass through the cover. The sensor device also includes a heater with a wire-like trace directly deposited on the interior surface of the cover formed of a fluid comprising an electrically conductive material that was deposited onto a portion of the cover and cured. The heater has an electrically conductive connector pad formed with the heater by directly depositing and curing the fluid comprising the electrically conductive material directly on the interior surface of the cover simultaneously with forming the heater. The heater is positioned and arranged to sufficiently heat the cover while not blocking an area through which radiation must pass for proper operation of the emitter and the detector.
