Problems solved by technology

However, due to manufacturing tolerances, such as non-uniform etching, non-uniform coating or non-uniform doping, the sensor device 1 may have certain defects 12
like figure 1 As shown, the defect 12 exists in a part of the detection line 11, when detected, it will cause the sensor device 1 to measure inaccurately
The multiplexer 22 and its wiring will increase the manufacturing complexity and cost of the sensor device 2

Abstract

A biosensor device includes a substrate, an oxide layer and a sensing wire. The oxide layer is disposed on the substrate. The sensing wire is disposed on the oxide layer. The sensing wire is providedto receive target biomolecules. The sensing wire includes at least one first section extending along a first direction and at least one second section extending along a second direction. The at leastone first section is continuous with the at least one second section. The first direction is different from the second direction. The sensing wire has a width and a total length and a ratio of the total length to the width is larger than 500.

Description

technical field [0001] The invention relates to the technical field of biological detection, in particular to a biological sensor device. Background technique [0002] Biosensors can be used to measure biological characteristics, such as blood cells, proteins, sugars, antibodies, or metal ions. The advantage of biosensor lies in its high specificity, high sensitivity and high selectivity, and it can be applied in fields such as medicine, biotechnology, food, agriculture and environmental monitoring. [0003] figure 1 A known sensor device 1 is shown in which a detection line 11 is used to detect target biomolecules. However, due to manufacturing tolerances, such as non-uniform etching, non-uniform coating or non-uniform doping, the sensor device 1 may have certain defects 12 . like figure 1 As shown, the defect 12 exists in a part of the detection line 11, which, when detected, will cause the sensor device 1 to measure inaccurately. [0004] figure 2 Another known sen...
