1. A device for sensing an analyte, comprising:
a membrane that allows diffusion of an analyte; an active measuring area for measuring a concentration of the analyte; a sensing chamber situated between the membrane and the active measuring area, the sensing chamber including a wall and comprising a mediating fluid, the chamber being enclosed by the membrane, the active measuring area and the chamber wall; and an element for producing convection within the mediating fluid to facilitate mixing of the analyte diffusing through the membrane in the mediating fluid to thereby reduce a response time for the active measuring area to measure the presence of the analyte in the mediating fluid.
