To record biopotentials, an interface is required between the electron-conducting copper wires connected to signal conditioning amplifiers and the ion-conducting environment of living organisms. Electrodes form this interface.
Some of the several kinds of electrodes are better than others … Read More
A key bioelectric signal that has diagnostic significance for various neuromuscular diseases is the electromyogram (EMG), which can be recorded from the skin surface with electrodes identical to those used for electrocardiography, although in some cases, the electrodes… Read More
We have different types of biopotential electrodes that are used in recording electromyographic (EMG) signals from different muscles in the body.
The shape and size of the recorded EMG signals depend on the electrical property of these electrodes and the … Read More
Biopotential measurements are done using different types of specialized electrodes. The work of these recording electrodes is to couple the ionic potentials generated inside the body to an electronic instrument.
Biopotential electrodes are classified either as non-invasive (skin surface) or … Read More
One key source of motion artifact in biopotential electrodes is the disturbance of the double layer of charge at the electrode-electrolyte interface. Employing non-polarizable electrodes like Ag/AgCl electrode can greatly reduce this artifact but it still can be present, and … Read More
Bioelectric potentials are ionic voltages produced when special types of cells perform electrochemical activities. These bioelectric potentials can be measured and the measurement results provide meaningful … Read More
Bioelectric events have to be picked up from the surface of the body before they can be put to the amplifier for subsequent record or display. This is done by use of electrodes. The potentials produced at different points … Read More
