Dry physiological recording device
First Claim
1. An attachable device for measuring biological characteristics or biopotential from the lower layers of the epidermis of the skin comprising:
- a substrate device comprising a substrate having an upper and lower surface and an array of penetrators protruding from the upper surface of the substrate, andan adhesive collar for mounting the substrate device to the skin;
wherein the penetrators are individually addressable and capable of piercing through the stratum corneum or outer layer of the epidermis and transmitting an electric potential from the lower layers of the epidermis which can be measured.

Abstract
The present invention relates to a dry physiological recording electrode that can be used without skin preparation or the use of electrolytic gels. The dry physiological recording electrode comprising 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 present invention also includes a method of sensing biopotentials in the skin.
