System for electrophysiological analysis of plants

Abstract

The invention relates to a system for electrophysiological analysis of plants, characterized in that it comprises: a plurality of acquisition systems, each acquisition system comprising: —a plurality of pairs of electrodes each comprising a first electrode and a second electrode each intended to be connected to the same plant in order to pick up first and second analog electric potentials, a plurality of operational amplifiers arranged in order to measure the differences in potential between the first and second analog electric potentials acquired by the first and second electrodes of said acquisition system and a plurality of analog-to-digital converters designed to convert the differences in potential into digital signals, —a central data collection system comprising a memory and a source of electrical power, characterized in that each acquisition system is connected to the central system and comprises: a connecting unit designed to transmit the digital signals to the central system, a power unit designed to transmit the electrical power obtained from the electrical energy source to the operational amplifiers and to the analog-to-digital converters, each acquisition system being designed to galvanically isolate the operational amplifiers and the analog-to-digital converters from the power unit and the connecting unit.
