BIOTELEMETRY

ABSTRACT
Biotelemetry is a vital constituent in the field of medical sciences. 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, Alzheimerís disease, mood disorders, cardiovascular problems, accidents, etc. A patientís 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 patientís 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.

†HISTORY OF BIOTELEMETRY
THE FIRST WILDLIFE TRANSMITTER
Above ground range: 25 yards
Below ground range: 8 yards
Transmitter breaking through the skin
Batteries last 161 days
FURTHER DEVELOPMENT NEEDED
Canít be used in any critters smaller than a woodchuck
Range of 18-25 yards not adequate for some species, or inaccessible locations
Transmitter could not be recovered after it died
EXTERNAL TRANSMITTER
Studied porcupines in Minnesota
Used miniature transmitters
Home made harnesses
Modified dog harnesses for immature
Allowed them to make general statements about porcupines
TRANSMITTER
