Abstract
Sensor devices including dissolvable tissue-piercing tips are provided. The sensor devices can be used in conjunction with dissolvable needles configured for inserting the sensor devices into a host. Hardening agents for strengthening membranes on sensor devices are also provided. Methods of using and fabricating sensor devices are also provided.
Claims13
A sensor device for measuring an analyte concentration in a host, the sensor device being configured for implantation in the 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;
- a piercing element at a distal end of the sensor unit, the piercing element configured to pierce skin of the host;
- and
- a mounting unit spaced from a tip of the sensor unit and configured to support the sensor device on an exterior surface of the skin of the host;
- wherein the sensor body comprises a stimulus-responsive material configured to move the sensor body from a first shape that is straight to a second shape that is curved, the stimulus responsive material comprising a shape memory material configured such that the sensor body has the first shape at a first temperature ex vivo, and moves from the first shape to the second shape responsive to a second temperature in vivo that is different than the first temperature.
