A microphone on an external unit gathers the sound and processes it; the processed signal is then transferred to an implanted unit that stimulates the auditory nerve through a microelectrode array.

The voltmeter or analog-to-digital converter to which the microelectrode is connected measures the electrical potential difference ( measured in volts ) between the microelectrode and a reference electrode.

For back and leg pain, intradiscal electrothermography, developed in the mid-1990s, relies on a microelectrode inserted into a desiccated or degenerated intervertebral disk to heat the outer layer.
35.
The flexible microelectrode array curved and attached to the inside of the eyeballs well, and optical coherence tomography images of the implanted arrays showed good biocompatibility by not tearing the cortical measurements.

Evidence from microelectrode recordings from the brains of animals shows that dopamine neurons in the ventral tegmental area ( VTA ) and substantia nigra are strongly activated by a wide variety of rewarding events.
37.
Increased spatial resolution is provided by CMOS-based high-density microelectrode arrays featuring thousands of electrodes along with integrated readout and stimulation circuits on compact chips of the size of a thumbnail.
38.
When one applies a variable voltage in this cell, the electrode large area remains unchanged, while the microelectrode undergoes a change of potential, ( i . e . is polarized ).
39.
To capture electrical signals from the brain, scientists have developed microelectrode arrays smaller than a square centimeter that can be implanted in the skull to record electrical activity, transducing recorded information through a thin cable.

A multi-electrode array ( MEA ), also commonly called a microelectrode array, is a patterned array of electrodes laid out in a transparent substrate used for communication with neurons in contact with it.
