Physiological recording device with harness to attach and method

摘要

The present invention relates to a physiological recording electrode, a method, and apparatus for attaching the physiological electrode to a subject. The physiological electrode comprises a substrate having an upper and a lower surface, and at least one penetrator(s) protruding from the upper surface of the substrate. The penetrator(s) is capable of piercing through the stratum corneum or outer layer of the skin, and transmitting an electric potential from the lower layers of the epidermis through the penetrator(s) which can be measured, or detecting agents from the lower layers of the epidermis primarily the stratum germinativum layer. At least one epidermis stop may be provided resulting in the formation of detritus troughs interposed between adjacent penetrator(s) and epidermis stops. The physiological electrode is attached to a subject by means of the apparatus and method for attaching same. The present invention also includes a method of sensing biopotentials in the skin.

主权项

1. A method of acquiring a physiological signal from a subject comprising steps of:
packaging at least one physiological electrode with a harness, the harness for mounting or holding the at least one physiological electrode to the subject's skin without using adhesive, wherein the at least one physiological electrode comprises a substrate having an upper and lower surface and at least one penetrator protruding from the upper surface of the substrate wherein the physiological electrode is capable of accessing lower layers of the epidermis to acquire a physiological signal from an ionic current in the lower layers of the epidermis of the subject; mounting the packaged electrode to the subject's skin with the harness; and acquiring a physiological signal from the subject, including a step wherein the physiological electrode is formed from a mold containing the image of the desired surface feature(s).
