Patent ID: 8620402

Claim:
A physiological sensor device attachable to the skin of a person for collecting physiological signals generated by the person's body comprising: a flexible front layer comprising a material that does not conduct electricity; a flexible back layer comprising a material that does not conduct electricity, the back layer including a plurality of portals, a back side of the back layer is provided with an adhesive for adhering the physiological sensor device to a patient; a releasable liner layer that is fixed to the back side of the back layer and is removable from the physiological sensor device before the physiological sensor device is attached to a patient; a flexible intermediate circuit layer comprising a material that does not conduct electricity sandwiched between and fixed to the front layer and the back layer, a plurality of electrodes and electrical conductors are fixed to a back side of the intermediate layer, each of the electrodes is attached to one of the electrical conductors and all of the electrical conductors are attached to a single common connector that protrudes through a portal in the front layer; and a plurality of conductive gel pads, each gel pad adhered to and aligned with and in conductive communication with one of the electrodes and protruding through one of the portals in the back layer; each layer of the physiological sensor device having, when attached to a standing person's chest, a vertically extending portion with a horizontally extending portion located at a lower end of the vertically extending portion and extending to both sides of the vertically extending portion, and the single common connector is disposed in the horizontally extending portion of the physiological sensor device and is aligned with the vertically extending portion of the physiological sensor device, the single common connector being a means for fixing a data collection device to a front surface of the front layer of the physiological sensor device.
