Abstract: A bio-sensor circuit for detecting characteristics of a substance placed thereupon, the bio-sensor circuit has: a printed circuit having at least one electrically conductive contact sensor on a surface of the printed circuit, the electrically conductive contact sensor including a biochemical agent; and an electrically insulative coating affixed to the surface of the printed circuit, the electrically insulative coating having a well associated with the electrically conductive contact sensor, thereby leaving the electrically conductive contact sensor exposed through the electrically insulative coating, the electrically insulative coating being a resinous compound formed by injection molding. An electrochemical change resulting from the interaction of the substance to be characterized and the biochemical agent creates a detectable electrical potential at the electrically conductive contact sensor. A system and method of creating such a circuit via injection molding is also provided.

Abstract: An electronic paper display module includes a substrate, a circuit layer disposed on one side of the substrate, an insulating layer disposed on the substrate and the circuit layer, an electronic paper display layer disposed on one side of the insulating layer opposite from the circuit layer and partially passes through the insulating layer to electrically connect with the circuit layer, an electrical connecting member, and a top protective layer disposed on the insulating layer and the electronic paper display layer. The top protective layer, insulating layer and circuit layer cooperatively seal the electronic paper display layer. The circuit layer, insulating layer, electrical connecting member and substrate cooperatively seal the circuit layer. A method for making the electronic paper display module and an electronic paper display device are also provided. A bottom protective layer is no longer required, which simplifies the fabrication process and reduces cost.

Abstract: A thermally-efficient electrical assembly comprising: an electrically-conductive layer; a heat sink layer; an electrically-insulating interconnecting layer interposed between the electrically-conductive layer and heat sink layer; an electrical component in electrical communication with the electrically-conductive layer; and a metallic thermal bridge in thermal communication with the electrical component and in direct contact with the heat sink layer, thereby bypassing the electrically-insulating layer.
