Sensing apparatus and process

The sensing device (10) which has a connector (16), and a sensor lead (12) and the sensor module (20) which has arranged the spacer (50) on the electrode (36) made to deposit on a substrate (30). The spacer (50) can have a space which accommodates enzyme. A forming bead (22) etc. Can enclose the end of a sensor module (20). A sensor lead (12) is attached to a sensor module (20), and has the outside tubing which passes through a module top and is attached to a bead (22) at the module end. You may attach a sensor lead (12) to a connector (16) so that a sensing device can electrically connect with a pump, an electronic device, or other equipment again. Embedding into a vein or an artery is possible for a sensing device (10).
