DEVICE TO STIMULATE OR RECORD A SIGNAL TO OR FROM A LIVING TISSUE

摘要

The invention concerns a device to stimulate or record a signal to or from a living tissue, comprising at least one electrically conductive first electrode comprising a zone for application to the living tissue and a conductor for sending or receiving a signal voltage to or from the zone. According to the invention, the zone (11) for application to the living tissue belonging to the first electrode (10) and/or supplementary conductive surface (3) has a first geometric surface made of at least one first conducting material and modified by an external organized mesoporous layer consisting in at least one second conducting material (M2por) having pore (POR) diameters within 1-10 nm.
