Continuous process for manufacture of disposable electro-chemical sensor
First Claim
1. A method for manufacturing electrochemical sensors comprising a substrate, an electrode layer and at least a first reagent layer, said method comprising the steps of transporting a continuous web of the substrate past at least two print stations and printing the electrode layer and the first reagent layer on the substrate, one of said print stations printing the electrode layer on the continuous web of substrate and the other said print stations printing the first reagent layer on the continuous web of substrate as it is transported past the print stations.

Abstract
Sensors formed from a substrate, an electrode layer and at least a first reagent layer are manufactured by transporting a continuous web of the substrate past at least two print stations, and printing the electrode layer and the first reagent layer on the substrate. One of the print stations prints the electrode layer on the continuous web of substrate, and the other of the print stations prints the first reagent layer on the continuous web of substrate as it is transported past the print stations. Additional print stations may be included for the printing of insulation layers, glue prints and the like. The order of printing will depend on the structure desired for the sensor, although the electrode layer(s) will frequently be deposited before the reagent layer(s).
