DEVELOPMENT OF A MINIATURE TELEMETRY SYSTEM,
Abstract
Experiments with VHF miniature transmitters submerged in physiologic saline solution to simulate their being implanted in living animals indicate that internal telemetry from small animals may be feasible at frequencies as high as 200 mc. Further study is needed before conclusions can be drawn relative to the frequency range best suited for large animals. Tests with transmitters below 20 mc. held under a person's armpit indicate that the human body is essentially transparent to internal telemetry signals in that frequency range. Modulation schemes, power supplies, and encapsulants are discussed. (Author)
