摘要：
A sensing assembly (10), including a body (12) and one or more first indicating electrodes disposed on the body (26). The first indicating electrodes include an electrochemically active layer (32) and a layer (38) of an active functioning enzyme of a first enzyme type on top of the electrochemically active layer. Also, one or more second indicating electrodes (24) are disposed on the body and include an electrochemically active layer (32) and a layer (36) of an inactivated enzyme of the first enzyme type on top of the electrochemically active layer. A reference electrode (22) is also disposed on the body. Finally, an electrical and data processing system (18) is adapted to bias the electrodes and measure electrical signals from the electrodes, and uses said signals to determine an analyte concentration and communicates the analyte concentration to a location apart from the first and second indicating electrodes.
