The first electrocardiogram was made with a single electrode attached to the body.

Silicon technology provides better mechanical stiffness and is a good supporting carrier to allow for multiple recording sites on a single electrode.

Their results showed that the subjects could identify different pitches that were proportional to the frequency stimulated by a single electrode.

For symmetric constructed supercapacitors the total capacitance value equal to half the value of a single electrode.

This printing stamped multiple batteries down on the surface of a single electrode.

For example, imagine that you want to create the simplest possible LCD with just a single rectangular electrode on it.

This single electrode carries out the functions of both current injection and recording.

A single electrode is a point source of current.

The oscillation between the two functions of the single electrode is termed a duty cycle.

If you take the layer that contains the single electrode and add a few more, you can begin to build more sophisticated displays.
