It entails remote measurement of biological parameters. Transmission of physiological data from point of generation to the point of reception can take many forms. Biotelemetry, using wireless diagnosis, can monitor electronically the symptoms and movements of patients. This development has opened up avenues for medical diagnosis and treatment. It enables monitoring of activity levels in patients suffering from heart troubles, asthma, pain, Alzheimer’s disease, mood disorders, cardiovascular problems, accidents, etc. A patient’s response and reaction to drugs can also be investigated for treatment. Radio telemetry transmits biological data using various radio transmission techniques. No wires are required to be attached to the patient’s body. The patient just carries a bracelet-sized transmitter that enables monitoring of the patients symptoms. Carrier modulation, physiological data encoding, frequency and time division multiplexing blocking oscillator or Endoradiosonde, receivers and antennas for Biotelemetry, power sources, and transcutaneous power transfer are discussed in this paper.
