Abstract
A skin-conformable and compact wearable sensor for monitoring surface physiological and/or surface brain signals of the wearer. The wearable sensor comprises a polymer adhesive. The adhesive polymer composition may include a silicone polymer and an amine-based polymer. The adhesive polymer composition may include from 1 to 10 wt. % amine-based polymer by weight of the adhesive polymer composition.
Claims20
A wearable sensor for monitoring physiological, or brain signals, or both, the sensor comprising:
- a thin flexible substrate comprising a skin-contacting surface, wherein the skin-contacting surface is at least partially coated in an adhesive polymer composition, the adhesive polymer composition comprising:
- a silicone polymer;
- and
- an amine-based polymer,
- wherein the adhesive polymer composition comprises from 1 to 10 wt. % amine-based polymer by weight of the adhesive polymer composition.
A method for manufacturing a wearable sensor for monitoring physiological, or brain signals, or both, the wearable sensor having a flexible substrate and at least one electrode pad, the method comprising:
- coating at least part of the flexible substrate in an adhesive polymer mixture, the adhesive polymer mixture comprising a silicone polymer, an amine-based polymer, and optionally a curing agent, wherein the adhesive polymer mixture comprises from 1 to 10 wt. % amine-based polymer by weight of the adhesive polymer mixture;
- curing the adhesive polymer mixture to obtain a cured adhesive polymer coating;
- coating at least part of the at least one electrode pad in a conductive polymer mixture, the mixture comprising an electrically-conductive material, at least one additive, a silicone polymer, and optionally a curing agent;
- curing the electrically-conductive polymer mixture to obtain a cured electrically-conductive polymer on the at least one electrode pad;
- and
- optionally, patterning a surface of the electrically-conductive polymer, prior to curing, to increase a surface area of the coating.
