Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
A biosignal electrode device, comprising: a) a flexible, electrically insulating substrate, and b) an electrically conductive layer deposited on a surface of said substrate, and forming thereon an electrode sensor for contacting a patient's skin, and a lead for the sensor, c) wherein a portion of the substrate bearing the sensor is formed in relief such that said substrate portion and attendantly the sensor are upstanding from surrounding substrate.
Claim 2
Dependent Claim
69 words
A biosignal electrode device, comprising: a) a flexible, electrically insulating substrate, and b) an electrically conductive layer deposited on a surface of said substrate, and forming thereon an electrode sensor for contacting a patient's skin, and a lead for the sensor, c) wherein a portion of the substrate bearing the sensor is formed in relief such that said substrate portion and attendantly the sensor are upstanding from surrounding substrate.
Claim 3
Dependent Claim
15 words
A device as claimed in claim 1, wherein the surface of the sensor is roughened.
Claim 4
Dependent Claim
34 words
A device as claimed in claim 1, wherein the lead is deposited on an opposite surface of the substrate from the sensor, and is connected to the sensor through an aperture in the substrate.
Claim 5
Dependent Claim
35 words
A device as claimed in claim 1, wherein the portion of the substrate which is in relief and bears the sensor is slightly recessed to form a well, and the well contains an electrolytic gel.
Claim 6
Dependent Claim
22 words
A device as claimed in claim 1, wherein there is a plurality of sensors and associated leads are provided on the substrate.
Claim 7
Dependent Claim
32 words
A device as claimed in claim 5, wherein regions of the substrate between the sensors and leads are removed to provide fingers of substrate, each bearing a sensor and an associated lead.
Claim 8
Dependent Claim
21 words
A device as claimed in claim 5, wherein the sensors are backed by a flexible and stretchable band of insulating material.
Claim 9
Dependent Claim
39 words
A device as claimed in claim 1, wherein a portion of the substrate remote from the sensor is formed into one part of a male/female connector having an electrically conductive layer thereon which is electrically connected to the lead.
Claim 10
Dependent Claim
57 words
A biosignal electrode assembly comprising a harness in the form of an electrically insulating substrate having a plurality of leads deposited thereon each terminating in one part of a male/female connector, and a plurality of biosignal electrode devices as claimed in claim 8 each connectable by its connector part to a respective connector part on the harness.
