In this study, two types of biological potential measuring system have been designed and established in order to bring a detailed sight on the biological information system. In the first system, two types of movable electrodes were developed to detect the potential changes on the leaf surface at a micro-scale level. These movable electrodes can be resiliently engaged onto the leaf geometry and are able to perform a multiple and simultaneous potential measurements at 1 and 2 mm pitch. They are also assisted with a pre-amplifier which can correspond to any fluctuation in impedances of each electrode. The second system is related to measuring system which an insertion depth of a micro-electrode into the leaf to be observed can be arbitrarily controlled by moving a micro-electrode in order to investigate a correlation between the leaf surface potential and intracellular potential of the leaf.
