Physical contact layer for body-worn leadware using selective deposition

摘要

A printed electrical circuit and methods for additively printing electrical circuits. Patterned layers of conductive, insulating, semi-conductive materials, and other materials are print deposited on a flexible or rigid substrate to form electrical circuits. A buffering layer is selectively deposited to cover or encapsulate these materials to comprise a comfort layer that provides a soft and comfortable interface to the skin of a wearer. The comfort layer can be selectively deposited on the same press that the conductive, insulating, semi-conductive materials, and other materials are deposited. Further, the comfort layer is selectively deposited only where it is desired and exactly where it is desired.

主权项

1. A body-worn electronic circuit assembly having a buffering feature, the electronic circuit assembly comprising:
a substrate; electronic circuitry including at least a conductive material deposited on a first side of the substrate; and a selectively deposited comfort layer encompassing at least a portion of the electronic circuitry, wherein the comfort layer provides the buffering feature such that substantially non-abrasive contact is made between the comfort layer and the skin of a wearer when the electronic circuit is placed on the wearer, wherein the portion of the electronic circuitry which is encompassed by the comfort layer does not contact the skin of the wearer, and wherein the substrate is not configured to be separated from the electronic circuitry.
