Abstract
A printed electric circuit comprises a printed planar substrate. The printed planar surface comprises one or more traces integrated into the printed planar structure. The one or more traces comprise a hydrophilic additive to create ion reservoirs within an organic semiconductor layer.
Claims15
A printed electric circuit, the printed electric circuit comprising:
- a printed planar substrate, the printed planar substrate comprising one or more traces integrated into the printed electric circuit;
- wherein the one or more traces comprise a hydrophilic additive to create ion reservoirs within an organic semiconductor layer;
- and
- a printed PEDOT:PSS ink layer forming the organic semiconductor layer, wherein the printed PEDOT:PSS ink layer has a thickness between 1 μm and 2.5 μm.
1 more element
A method for printing an electric circuit, the method comprising:
- printing onto a substrate a first layer comprising an Ag ink,
- printing onto the substrate a second layer comprising an Ag/AgCl ink,
- printing onto the substrate a third layer comprising a PEDOT:PSS ink,
- wherein the third layer further comprises a hydrophilic additive to create ion reservoirs within the third layer, wherein printing the third layer comprises forming an organic semiconducting channel with a thickness between 1 μm and 2.5 μm, and
- printing onto the substrate a fourth layer comprising dielectric ink.
