Biomedical Electrodes
  • Electrodes are first receiver of biomedical
    signal from the surface of the body/internal of
    the body.
  • Receiving signals are given into the input of
    preamplifier that converts ionic conduction of
    tissues into electronic conduction.

3
Types of electrodes
  • Body surface electrodes
  • Internal electrodes

4
Body surface electrodes
  • It is Placed on the surface of the body
  • Examples
  • Metal-plate electrodes
  • Floating electrodes
  • Flexible electrodes
  • Dry electrodes

5
Internal electrodes
  • It is Inserted into the body (Needles)
  • Wires Implanted electronic circuits
  • Example
  • Radio telemetry transmitter

6
Electrodes for ECG
  • Limb Electrodes
  • Floating Electrodes
  • Pregelled Disposable Electrodes
  • Paste less Electrodes
  • Air-Jet Electrodes

7
Electrodes foe EMG
  • Pad Electrode
  • Chloride silver wire
  • Needle type
  • Hypodermic needle type
  • Metal type micro electrode
  • Micropipet Electrode

8
Electrodes for EEG
  • Chloride Silver Discs Electrode used for general
    study
  • Needle Electrode used for special study
