The science of measuring and transmitting biological data from living organisms, especially at a distance using electronic devices.
From bio- (life) + telemetry (Greek tele, distant + metron, measure). Developed in the 1960s for space programs and wildlife research.
Biotelemetry made it possible to learn what astronauts' bodies were doing in space and how wild animals behave without disturbing them—both revolutionized their fields!
