Description

technical field [0001] A biochemical enzyme test bare chip, especially a test bare chip that can improve measurement accuracy and be used in multiple points on a single chip. Background technique [0002] With the advancement of science and technology, many basic tests that could only be performed in hospitals in the early days, such as: electrochemical enzyme test, blood sugar, urine, saliva test, etc., have become home-type instruments and equipment, and there are even portable ones. Personal instruments, so that patients can perform testing actions by themselves at any time. However, all kinds of instruments and equipment need to use enzyme test chips for testing. At this stage, the test chips have the following deficiencies: [0003] 1. At present, the printing method is widely used to test the conductive lines on the surface of the bare chip. Silver glue or carbon glue is printed on the circuit board. Due to the low density of silver glue or carbon glue, the flatness of...

Problems solved by technology

[0003] 1. At present, the printing method is widely used to test the conductive lines on the surface of the bare chip. Silver glue or carbon glue is printed on the circuit board. Due to the low density of silver glue or carbon glue, the flatness of the surface is poor, and the tested The liquid cannot effectively contact the conductive circuit, so it is necessary to increase the area of ​​the conductive circuit and increase the test liquid to produce a large area of ​​body fluid to test the contact conductive circuit, resulting in a large error in the test result, and the operating voltage of the general test instrument and The current is quite small, and some contact areas are insufficient, which will cause considerable interpretation errors in test results

[0004] 2. Nowadays, single-chip single-point testing is mostly used for testing bare chips, that is, a single chip can only be tested once, which is a waste of resources. If the conductive lines of multiple chip groups are printed on a single circuit substrate, the impedance will be different. The problem of matching
