Dry physiological recording device
First Claim
1. A method of forming a dry physiological recording electrode having an upper and a lower surface and desired surface features, the method comprising the step of:
- forming a dry physiological electrode comprising an upper surface, a lower surface and at least one penetrator(s) protruding from the upper surface of the dry physiological electrode from another surface, the other surface having a negative image of the desired surface features of the dry physiological electrodewherein the at least one penetrator is capable of piercing through the stratum corneum or outer layer of the skin and transmitting an electric potential from a lower layer of the epidermis of the skin.

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 epidmermis 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.

10. A method of forming a device having an upper and a lower surface and desired surface features, the device for measuring biological characteristics or biopotential from the lower layers of the epidermis of the skin, the method comprising the step of:
-
forming a device comprising an upper surface, a lower surface, at least one first penetrator(s) protruding from the upper surface of the device and at least one second penetrator(s) having an aspect ratio of less than about 1.5 protruding from the upper surface of the device from another surface, the other surface having a negative image of the desired surface features of the device wherein the at least one first penetrator is capable of piercing through the stratum corneum or outer layer of the skin and transmitting an electric potential from a lower layer of the epidermis of the skin and the at least one second penetrator assists in anchoring the device to a subject'"'"'s skin. - View Dependent Claims (11, 12, 13, 14)
