## Abstract

An autonomous neurostimulation unit used in the modulation of the nervous system is provided and has: at least one pair of pads, each formed by at least one inner layer of ceramic; an intermediate layer; and a conductive alloy coating. The material of the layer of coating is different and has different conductivity in each of the pads of the pair. The unit can be used in the modulation of the nervous system, with neurostimulation methods that are adapted to each patient.

## Claims
