Dry physiological recording device and method of manufacturing
First Claim
1. A physiological recording device comprising:
- a recording portion comprising an upper surface and a lower surface, the lower surface comprising at least one surface feature for connecting to lower layers of a subject'"'"'s skin and obtaining at least one physiological signal from the lower layers of the skin, the upper surface comprising a connector connecting the recording portion to a physiological monitoring or recording device for passing along the at least one physiological signal from the lower surface, anda separate encouragement ring, the encouragement ring having an opening for surrounding and holding the recording portion, and a lower surface that slopes upward, with at least one radius of curvature and at least one distance of curvature, from its center so as to help stabilize and situate the device against the subject'"'"'s skin.

Abstract
The present invention is directed to a physiological recording device and, more particularly, to a physiological recording device that can be used without skin preparation or the use of electrolytic gels. The invention is further directed to an encouragement ring which stabilizes and helps situate the physiological recording device on a subject'"'"'s skin to help provide a better electrical signal, increase surface area, and reduce and minimize noise and artifacts during the process of recording or monitoring a physiological signal. The invention is still further directed to surface features on a surface of the physiological recording device with a size and shape that will not substantially bend or break, which limits the depth of application of the recording device, and/or anchors the recording device during normal application. The invention is even further directed to a method for manufacturing a physiological recording device, and minimizing cost of manufacture.
