Title:
ELECTRONIC INTEGRATED MULTI-ELECTRODE DETECTION SYSTEM BASED ON POTENTIAL MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/2018/149380
Kind Code:
A1
Abstract:
An electronic integrated multi-electrode detection system based on potential measurement. The detection system comprises a multi-electrode array (10), a circuit unit (20), and a total signal output and acquisition (30). The circuit unit (20) primarily comprises a multi-electrode array signal output end (21), a high input impedance voltage follower (22), a phase-shifting filter circuit (23), an expandable module input end (24), a summation circuit (25) and a total output signal end (26). The detection system is capable of significantly enhancing detection sensitivity as well as the accuracy and precision of detection results. Furthermore, the detection system can be applied to the monitoring of minute changes in ion concentration in samples, analysis of constant normal samples and sample analysis with higher error requirements, and can also be extensively applied to various analysis and detection fields including life sciences, environmental sciences and drug clinical applications. The solution of the present invention is suitable for all universal multi-electrode detection systems based on potential measurement.
