Electrochemical sensor array and apparatus
First Claim
1. An apparatus having an electrochemical sensor array for analyzing a sample comprising:
- at least one upper layer;
at least one inlet opening and at least one outlet opening, wherein the inlet opening and the outlet opening are arranged on the upper layer;
at least one lower layer having a recess thereon;
at least one first two-sided adhesive membrane matching to the recess on the lower layer;
at least one sensor array secured to the lower layer and embedded within the recess through the first two-sided adhesive membrane, wherein the sensor array includes at least one working electrode, at least one reference electrode, at least one counter electrode, at least one communication channel, and at least one conductive line, wherein the conductive line provides a connection between the working electrode and the communication channel;
wherein the working electrode, the reference electrode, and the counter electrode are integrally formed on an upper surface of a plate;
at least one measuring device associated with the communication channel;
at least one second two-sided adhesive membrane spaced from the first two-sided adhesive membrane, wherein the second two-sided adhesive membrane is provided between the sensor array and the lower layer, such that the sensor array is secured to the upper layer, the second two-sided adhesive membrane is placed adjacent to the upper layer and is provided with an opening;
at least one flow channel formed between the upper layer and the sensor array as a result of the opening wherein the flow channel is associated with the inlet opening and the outlet opening located on the upper layer for carrying the sample.
