Biomedical Electrodes Presented by- Md. Bashir Uddin Roll: Dept. of BME KUET, Khulna-9203
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.
Body surface electrodes Internal electrodes
It is Placed on the surface of the body Examples: Metal-plate electrodes Floating electrodes Flexible electrodes Dry electrodes
It is Inserted into the body (Needles) Wires Implanted electronic circuits Example: Radio telemetry transmitter
Limb Electrodes Floating Electrodes Pregelled Disposable Electrodes Paste less Electrodes Air-Jet Electrodes
Pad Electrode Chloride silver wire Needle type Hypodermic needle type Metal type micro electrode Micropipet Electrode
Chloride Silver Discs Electrode used for general study Needle Electrode used for special study
