1. A system comprising:
- at least one gas collection chamber into which a tissue constituent is able to diffuse, wherein the gas collection chamber is adapted to be placed proximate to a tissue;
an efferent conduit adapted to transfer the tissue constituent from the gas collection chamber to at least one sensing component, wherein the sensing component is adapted to provide a signal related to the tissue constituent;
an afferent conduit adapted to transfer the tissue constituent from the sensing component to the gas collection chamber; and
a motive force structure adapted circulate the tissue constituent through the system, wherein the motive force structure is adapted to be operatively connected to at least one of the efferent conduit, the afferent conduit, or the sensing component.

Abstract
A sensor is provided that is appropriate for transcutaneous detection of tissue or blood constituents. A sensor for tissue constituent detection may include a gas collection chamber with a conduit to a sensing component and a conduit from the sensing component to the chamber. A sensor as provided may also include a barrier layer to prevent water from infiltrating the sensor.
