Resistance element and biosensor

Abstract

The invention discloses a resistance element. The resistance element comprises at least one electrode and at least one resistor, wherein the electrode is provided with at least two fractures and at least one contact; and multiple electrode sections formed by the fractures are parallel to one another, and every two adjacent electrode sections are connected through the resistor with a resistance value which is changed through laser cutting or burning. The invention also discloses a biosensor. The biosensor comprises a substrate layer and an electrode layer, wherein the electrode layer is provided with the resistance element; The invention further discloses another biosensor. The another biosensor comprises a substrate layer and an electrode layer, wherein the electrode layer is provided witha startup resistor structure, and the startup resistor structure is obtained by connecting any electrode of the electrode layer with the resistor element in series. According to the invention, the upper limit of a resistance value can be freely increased, and the resistance value with a certain distinction degree is multiplied, so more biosensor codes are obtained, more information is stored, andprocess realization difficulty is reduced; and starting-up resistors can also be arranged, and the number of distinguishable starting-up resistors is increased.

Description

technical field [0001] The invention belongs to the field of biosensors, in particular to a resistance element and a biosensor. Background technique [0002] The coding method in the prior art is to connect a resistor to the two electrodes, change the resistance value by laser cutting or burning, and use different resistance values ​​as different codes. distinction. Although compared with the traditional coding method, the coding method of the existing technology has greatly increased the number of codes, but with the development of technology, there is a need to detect multiple indicators on a single biosensor, and the number of existing codes is limited to a certain extent. will not be able to meet demand. Whether it is increasing the distance between two electrodes or increasing the length of the resistor, it cannot meet the requirement of increasing the number of resistance values ​​with a certain distinction, and also cannot meet the requirement of increasing the numb...

AI Technical Summary

Problems solved by technology

The method of increasing the resistance by increasing the electrode spacing needs to increase the lateral area of ​​the biosensor, which does not meet the general size requirements, and due to the parallel connection of resistors, the increase in the lateral area does not increase the resistance value proportionally.

And increasing the length of the resistor will only provide a smaller lower limit of the resistance value, which will not help the differentiation of the resistance value
