Hardening agents for strengthening membranes on sensor devices are also provided. Methods of using and fabricating sensor devices are also provided.
Claims17
1-20. (canceled)
A sensor device for measuring an analyte concentration in a host, the sensor device comprising:
- a sensor unit comprising a sensor body, at least one electrode, and a membrane covering at least a portion of the at least one electrode;
- and
- a mounting unit spaced from the sensor tip and configured to support the sensor device on an exterior surface of the host's skin;
- wherein the membrane comprises a hardening agent, the hardening agent increasing a column strength of the sensor unit and increasing an adhesion of the membrane to the at least one electrode;
- and
- wherein the membrane comprising the hardening agent allows analyte permeability.
3 more elements
A method of making a sensor device, the method comprising:
- coating a wire with a membrane;
- cutting the coated wire to a desired length to thereby form a sensor tip;
- and
- exposing the coated wire to a hardening agent such that the membrane absorbs the hardening agent.
