MEASUREMENT DEVICE AND MEASUREMENT METHOD FOR MARINE ORGANISM PHYSIOLOGY

摘要

PROBLEM TO BE SOLVED: To provide a physiology measurement technique which enables the physiology of a marine organism to be easily and stably measured, and has low invasiveness.;SOLUTION: A measurement device 10 for marine organism physiology is provided, comprising; a physiology measurement circuit having a measurement input portion receiving a bioelectric signal of a measurement region from the marine organism in electrolyte-containing water, and a reference input portion receiving the electrical potential of the electrolyte-containing water including the marine organism; a measurement lead 17 having a coating layer for insulation, exposed from the coating layer at one end side, and constituting a biological electrode 13, and connected to the measurement input portion at the other end side; and a reference lead 15 having a reference electrode at one end, and connected to the reference input portion at the other end. The measurement lead electrically detects the bioelectric signal from the measurement lead in a state that the coating layer of the biological electrode and a portion adjoining the biological electrode is stuck into the marine organism, and sends the bioelectric signal from the measurement lead to the physiology measurement circuit. The reference lead sends the electrical potential of the electrolyte-containing water to the physiology measurement circuit in a state that the reference electrode is arranged in the electrolyte-containing water.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2021,JPO&INPIT
