The invention relates to a device for stimulating living tissue, comprising an array (1) of stimulating microelectrodes (11) that are placed in a defined configuration side by side and able to be selected by applying an electrical signal for stimulation by one of the microelectrodes. According to the invention, an additional conducting surface (3) for application against the living tissue, is provided in the vicinity of a defined plurality of sections (210) for local application of microelectrodes (11), connecting means (32) being provided for electrical connection between the zones (31), and the additional conducting surface (3) being also connected to a lead (33) and being formed so as to ensure local stimulation via a microelectrode (11).
L'invention concerne un dispositif de stimulation d'un tissu vivant, comprenant une matrice (1) de microélectrodes (11) de stimulation, disposées selon une configuration déterminée côte à côte et sélectionnables pour l'application d'un signal électrique de stimulation par l'une des microélectrodes. Suivant l'invention, il est prévu une surface supplémentaire (3) conductrice d'application contre le tissu vivant, au voisinage d'une pluralité déterminée de sections (210) d'application locale de microélectrodes (11), des moyens (32) de liaison étant prévus pour assurer une liaison électrique entre les zones (31), la surface conductrice supplémentaire (3) étant reliée en outre à un accès (33) et étant formée pour assurer une stimulation focale à partir d'une microélectrode (11).
