These devices include any of packaging and/or loading systems, applicators and elements of the on-body sensor units themselves. Also, various approaches to connecting electrochemical analyte sensors to and/or within associated on-body analyte sensor units are disclosed. The connector approaches variously involve the use of unique sensor and ancillary element arrangements to facilitate assembly of separate electronics assemblies and sensor elements that are kept apart until the end user brings them together. | 05-05-2022 |
20220135763 | BIO-ELECTRODE COMPOSITION, BIO-ELECTRODE, METHOD FOR MANUFACTURING BIO-ELECTRODE, AND REACTION COMPOSITE - A bio-electrode composition contains (A) a reaction composite of an ionic polymer material and a carbon particle. The component (A) contains the carbon particle bonding to the polymer containing a repeating unit having a structure selected from the group consisting of salts of ammonium, lithium, sodium, potassium, and silver formed with any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide. Thus, the present invention provides: a bio-electrode composition capable of forming a living body contact layer for a bio-electrode which is excellent in electric conductivity and biocompatibility, light-weight, and manufacturable at low cost, and which prevents significant reduction in the electric conductivity even when wetted with water or dried; a bio-electrode including a living body contact layer formed of the bio-electrode composition; and a method for manufacturing the bio-electrode. | 05-05-2022 |
