Bio – Telemetry System

Study of Bio – Telemetry system

Physiological parameters adaptable to biotelemetry can be broadly classified in two ways:

  1. Bioelectrical parameters like ECG
  2. Physiological variables like Body temperatures and pulse rate.

The first category signals are in the electrical form, but the second category signals have to be sensed and converted into electrical signal using resistive, capacitive and inductive transducers. The signals obtained from these transducers can be calibrated to represent the temperature and pressure. The signal obtained from the transducer or electrode is amplified and converted into a form of code that can be transmitted. The transmitted signal received at the receiving end will be decoded to get back the original form. The coding, transmission and decoding processes may involve amplification also. If the data will be useful for future use then it can be stored.
