A Short Range Underwater Biotelemetry System
نویسنده
چکیده
The requirement for monitoring the physiological functions of the test subject in weightlessness simulation activities coupled with the advantages of using telemetry for such monitoring led to the development of a biotelemetry system. One valuable technique for simulation of weightlessness uses the neutral buoyancy obtained by having the subject under water, which leads to a requirement that the telemetry system work in this medium. Previous underwater telemetry systems have usually used ultrasonic carriers. The system described in this paper is unique in providing a multiple channel underwater telemetry system using an electromagnetic carrier. The development of transducers used with this system to provide information on the work load Imposed by various simulation tasks is also described.

Accurately estimating contacts between animals can be critical in ecological studies such as examining social structure, predator-prey interactions or transmission of information and disease. While biotelemetry has been used successfully for such studies in terrestrial systems, it is still under development in the aquatic environment. Acoustic telemetry represents an attractive tool to investig...
