| Outline of Final Research Achievements |
Battery has been one of the constraints for monitoring longer-term movement of aquatic animals by animal-borne data-loggers. To overcome this, a prototype using a vibration-powered generator was developed, and the feasibility was investigated. The system was composed of a vibration-powered generator and data-logger with acceleration, pressure, and temperature sensors, and they were connected via a 5-m bending resistance cable. The system can start when enough voltage is charged in a capacitor inside. The generator was attached to the peduncle of the fish with another small data-logger to measure the acceleration of caudal fin movement, and then the fish was released in a tank. While the fish actively swam in the tank, it was impossible to initiate the sensor measurements because there was not enough charged. However, the voltage manually charged before the experiment, decreased more slowly in the fish experiment than that of the control experiment without the generator.
