Bio Electrode Potential

Electrode Potential The human body generates electrical signals on the body surface. Recording electrodes picks the bioelectric events produced in the body. The picked up signals are given to the amplifier and then to display. Electrodes transfer ionic conduction in the tissue to electronic conduction to measure the values. Generally, there are two types of … Read more

Action Potential and Resting Potential

In a cell membrane, the outside fluid is extra-cellular fluid and inside fluid is intra-cellular fluid. The extra-cellular fluid has a large concentration of sodium ions and chloride ions but less concentration of potassium ions. The intra-cellular fluid has a high concentration of potassium ions than the sodium ions. In our body, neuron sends electrochemical … Read more

Surface Electrodes

Surface electrode measures the potential available from the surface of the skin. It senses the signal from heart, brain and nerves. Larger surface electrodes sense the ECG signals. Smaller surface electrodes sense the EMG and EEG signals. The types of surface electrodes are as follows. Metal Plate Electrodes ECG measurement technique uses either rectangular or … Read more

Electrodes Used in Medical Applications

Electrode is a solid electric conductor through which an electric current enters or leaves an electrolytic cell. It converts ionic potentials to electronic potentials. Different types of electrodes used for biological measurements depend on the anatomical locations, from where the bioelectric signals are measured. Bioelectric electrodes acquire the signals like ECG, EEG, EMG, etc. There … Read more
