Publication number: 20220296146Abstract: An electrode includes a backing. The backing includes a first backing side and a second backing side. The backing has a planar surface and a portion of the backing forms a raised section on the first backing side and an indented section on the second backing side opposite the raised section. The indented section forms a cavity therein. Further, the backing is not electrically conductive. The electrode also includes an electrically conductive gel disposed at least partially within the cavity. The electrode further includes an eyelet penetrating the backing and electrically coupled with the electrically conductive gel. The electrode includes a stud adapted to detachably couple the electrode to a lead wire and configured to attach to the eyelet.Type: ApplicationFiled: September 4, 2020Publication date: September 22, 2022Inventors: John P. TRYPHONOPOULOS, Cameron E. DERRY, Howard P. NEUFELD

Patent number: 10857704Abstract: A process for producing an eyelet for a biomedical electrode (e.g. an electrocardiogram (ECG) electrode) involves: hot pressing an electrically conductive thermoplastic or elastomeric resin to produce a film having a web of eyelets, each eyelet having a post protruding from a first face of the film and a flange at a second face of the film; applying a coating of a non-polarizable conductive material (e.g. a silver-containing material) on to a contact face of the flange; and, cutting the film to produce the eyelets separated from the web. Preferably, the process involves extrusion replication. A web of eyelets for biomedical electrodes has a film of an electrically conductive thermoplastic or elastomeric resin possessing a plurality of posts protruding from a first face of the film, and preferably a layer of a non-polarizable conductive material on a second face of the film. The process may be a one-step continuous process that is cheaper and simpler than current commercial processes.Type: GrantFiled: March 30, 2020Date of Patent: December 8, 2020Assignee: 3M Innovative Properties CompanyInventors: Cameron E.

Patent number: 10800079Abstract: A process for producing a sensor for a biomedical electrode (e.g. an ECG electrode) involves injection molding an electrically conductive resin through a film of a backing material to form the sensor directly in the backing material and coating the contact face of the sensor with a non-polarizable conductive material (e.g. silver-containing material). Additional steps of applying an electrolyte over the non-polarizable conductive material coated on the contact face and applying a liner over the electrolyte results in the biomedical electrode. Biomedical electrode produced thereby have the sensor secured in a film of the backing material with a contact face of the sensor disposed on a first side of the film and a post of the sensor protruding from a second side of the film opposite the first side. The process permits production of one-piece sensors for bioelectrodes in a continuous fashion without the need for studs to retain sensors in a film of the backing material.Type: GrantFiled: December 29, 2016Date of Patent: October 13, 2020Assignee: 3M Innovative Properties CompanyInventors: Cameron E.
