An electrical stimulation system including: a mechanism generating at least one electrical signal to be applied to a biological tissue that is to stimulated and measuring a response of the biological tissue to each electrical signal; a calculation mechanism estimating, based on each electrical signal and on a corresponding response of the biological tissue, at least one parameter of an electrical model of the biological tissue and its interface with the electrical stimulation system and determining, using the model, at least one parameter of a stimulation pulse to be applied to the biological tissue by the electrical stimulation system; and a mechanism generating a stimulation pulse to be applied to the biological tissue.

Devices for electrical stimulation of a biological tissue and method for calibrating same

The present invention relates to a method for forming a crystallized silicon layer made up of grains having an average size of no less than 20 &#x3bc;m, including at least the steps that comprise: (1) providing a layer of silicon to be (re)crystallized, the average grain size of which is less than 10 &#x3bc;m; (2) placing said layer of silicon to be (re)crystallized in contact with a liquid composition at least partially made up of a metal solvent; and (3) exposing the assembly to a thermal treatment suitable for (re)crystallizing said layer of silicon with the expected grain size, characterized in that said thermal treatment includes heating the assembly made up of the layer of silicon in contact with said liquid composition to a temperature that is lower than 1410&#xb0; C. and at least equal to the eutectic temperature in the solvent-silicon phase diagram.
