Physiological recording device or electrode
First Claim
1. A method of forming a physiological recording electrode having an upper surface and a lower surface, and desired surface features, the electrode for measuring biopotentials from a subject having skin, the method comprising the steps of:
- forming in a mold by injection molding, casting or deposition a physiological recording electrode comprising an upper surface and a lower surface, the upper surface comprising a connector and the lower surface comprising at least one penetrator(s) protruding from the lower surface,wherein the at least one penetrator of the lower surface is capable of piercing through a stratum corneum or outer layer of the skin and transmitting an electric potential from a lower layer of a epidermis of the skin of the subject.

Abstract
The present invention is directed to a physiological recording device, or other types of sensors to detect a biopotential, and more particularly, a physiological recording electrode that can be used without skin preparation or the use of electrolytic gels. The invention is further directed to the configurations of structures on the physiological recording electrode'"'"'s lower surface. The structures having a length, width, and height, which are capable, at least in part, of transmitting an electric potential from the skin which can be measured. The structures may or may not limit the depth of application, and/or anchor the electrode or other device during normal application, and/or allow for uniform application of the electrode or other device over unprepared skin.
