APPARATUS FOR MEASURING IMPEDANCE OF CELL HAVING FILTER TYPE ELECTRODE AND FABRICATION METHOD OF THE SAME

摘要

PURPOSE: A device for measuring the impedance of a cell with a filter type electrode and a method for manufacturing the device are provided to measure the electrical properties caused by the deformability of the cell using only one electrode. CONSTITUTION: A device(100) for measuring the impedance of a cell with a filter type electrode comprises a substrate(110), a channel forming layer(120), and a filter type electrode. The channel forming layer is formed on the substrate and comprises an inlet(121), an outlet(123), and a fine fluidic channel(125). The channel forming layer connects the inlet and the outlet. The filter type electrode occupying a layer identical to the channel forming layer on the substrate is connected to the corresponding fine fluidic channel, thereby functioning as a fluidic channel. The filter type electrode comprises a first electrode(131) and a second electrode(132) which are spaced from each other. An impedance measuring device(143) is connected to the filter type electrode. An electrode separation formed on the filter type electrode becomes narrower along the route direction of the fine fluidic channel.
