Abstract: The present invention is directed towards a method of manufacturing a sensor disc for use as a dry electrode in a skin conductance measuring device, the sensor disc comprising a plurality of layers of different materials and the method of manufacturing comprising the steps of etching a copper base layer; electroplating the copper base layer with an intermediate bright copper layer; plating the intermediate bright copper layer with an intermediate palladium plated layer; and, plating the intermediate palladium plated layer with a gold plated surface layer. The advantage of a method of manufacturing a sensor disc in accordance with the present invention is that a roughened surface is created by the etching. This increased roughness corresponds to an increase in surface area of skin in contact with the sensor disc.

Abstract: In part, one aspect of the invention relates to a portable, handheld biosensor device that is held between two fingers of the same hand or otherwise contacts two points on a user's skin. The sensor device includes a pair of conductive or semi-conductive electrodes and associated circuitry designed to sense, amplify and digitize the electrical conductance of the skin between the electrodes. The device can additionally be configured to sense additional biometrics from the fingers, including blood oxygenation and skin temperature. Digitized biometric values are transmitted wirelessly (or via direct wire connection, such as a USB cable) to a computing device where the data is utilized to generate a control parameter in a software application whose purpose is to provide anxiety biofeedback or entertainment.
