  • Publication number: 20220143395
    Abstract: This invention addresses the need for efficient dry skin electrodes. Robust, flexible Mixed Ionic Electronic Conductor (MIEC) electrodes were prepared by an aqueous solution route resulting in electrically conductive networks of carbon nanotubes (CNTs) and ionically conductive elastic matrix. The flexible electrode was characterized in terms of conductivity, ionic charge transfer resistance, and water uptake. The flexible electrode maintained low resistance even after multiple cycles of 50% extension and contraction.

  • Patent number: 10982101
    Abstract: A method of making CNT films is described in which the film is washed with a mild acid treatment. The method generates a CNT film that is not sensitive to moisture or fluctuations in moisture. The method involves the use of anionic polysaccharides or anionic glycosaminoglycans such as hyaluronic acid, sodium salt, as aqueous dispersing agents and their modification to a hydrophobic matrix after deposition. In the course of conducting the work described here, we made the surprising discovery that washing with an aqueous acidic solution resulted in a decrease in resistance through the material. The invention also includes CNT composites made by the inventive methods and a CNT composite comprising CNTs and anionic polysaccharides or anionic glycosaminoglycans further characterized by a low cationic content and a high conductivity and/or small CNT particle size as measured by SEM.

  • Patent number: 10765859
    Abstract: The present disclosure relates to neuromuscular stimulation and sensing cuffs. The neuromuscular stimulation cuff has at least two fingers and a plurality of electrodes disposed on each finger. More generally, the neuromuscular stimulation cuff includes an outer, reusable component and an inner, disposable component. One or more electrodes are housed within the reusable component. The neuromuscular stimulation cuff may be produced by providing an insulating substrate layer, forming a conductive circuit on the substrate layer to form a conductive circuit layer, adhering a cover layer onto the conductive circuit layer to form a flexible circuit, and cutting at least one flexible finger from the flexible circuit. The neuromuscular stimulation cuff employs a flexible multi-electrode design which allows for reanimation of complex muscle movements in a patient, including individual finger movement.
