Biological behavior biosensor

Abstract

The invention relates to a biological behavior biosensor, which is characterized by comprising two series connected cavities, wherein a screen is arranged between the two cavities; outer ends of the two cavities are fixedly provided with a round cap respectively; the center of each round cap is provided with a water pipe connector; at least one group of electrodes is arranged in each cavity; each group of electrodes is formed by two pairs of electrodes which are arranged oppositely; one pair of electrodes is emission electrodes, and the other pair of electrodes is signal receiving electrodes; and the two pairs of electrodes are respectively connected with a water quality safety on-line warning system. The biological behavior biosensor provided by the invention is applied to the water quality safety on-line monitoring and warning system and is used for monitoring dynamic water, when in detection, a tested organism is put in one cavity while nothing is put in the other cavity, and a signal difference sensed by the two cavities is adopted as the behavior change of the tested organism, so that the influence of an external environment is removed, the behavior change of the tested organism in the environment is furthest monitored in real time, a biological behavior signal with normal frequency as well as high frequency and low intensity can be monitored, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to a sensor for water environment monitoring, in particular to a biological behavior sensor used in an on-line monitoring and early warning system for water quality safety. Background technique [0002] In order to protect the living environment quality of aquatic organisms and the safety and health of human drinking water, people often use various methods to monitor the quality of water environment, so as to effectively realize the safety warning of water environment quality. The biological monitoring of water bodies is the standard and basis to reflect the quality of the water environment. It directly reflects the impact and harm of the changes in the quality of the water environment on organisms. It is the most direct and effective means to achieve the purpose of water environment monitoring. [0003] There are several types of biological monitoring: 1. On-line bioluminescent detection technology, which utilizes the characteris...

Problems solved by technology

However, the biological behavior sensor currently used in this system is susceptible to external interference when monitoring water quality, and cannot monitor changes in high-frequency and low-intensity biological behavior

[0004] Invention patent application (name: biological behavior sensor for water quality safety online warning system, application number: 200710065436.9) discloses a biological behavior sensor that monitors water quality safety by detecting the avoidance behavior of living things under certain environmental pressure. In addition to biological behavior, the signals sensed by the cavity structure also include external signals, such as external noise, vibration and other signals, and cannot detect high-frequency and low-intensity biological behavior signals, which makes the water quality monitoring results inaccurate

In addition, the existing bio-behavior sensors usually use flat-plate electrodes, which cannot be evenly distributed in the cavity, and the electric field range is small, which makes it impossible to collect some useful signals with low intensity and high frequency. It can better reflect the behavior changes of organisms in the environment of low concentration of toxic substances, therefore, this also affects the accuracy of water quality monitoring results
