A system for maintaining the freshness of an object of preservation comprising an electrode made of a flexible conducting polymer. The system includes: an electrode module comprising a first electrode and a second electrode which face each other; and an electric field supply module generating an electric field between the first electrode and the second electrode by supplying a voltage to the electrode module, and where the first electrode is comprised of a flexible conducting polymer material.

A device for separating micro particles is provided. The separating device comprises a sample inlet into which a sample containing micro particles is injected; fluid inlets into which fluid is injected to form a flow sheath for the sample; a plurality of outlets through which the micro particles are separated and discharged out; a channel through which the sample and the fluid flow; and a first electrode and a second electrode longitudinally disposed in parallel in the channel. The first and the second electrodes are provided in such a manner that an electrode gap between the first and the second electrodes has a curved shape. The micro particles in the sample are easily separated using a dielectrophoresis characteristic.

A device for detecting micro particles in gas, which comprises: an inlet through which a gaseous sample including micro particles flows in; an outlet through which the sample flows out; a channel through which the sample flows from the inlet toward the outlet; a cooling layer which cools and condenses the sample flowing in the channel; a reservoir which is positioned on the cooling layer and collects the condensed sample; a detector which is positioned in the reservoir on the cooling layer and detects the micro particles included in the collected sample; and a heater which heats the outlet portion to produce a pressure difference between the inlet portion and the outlet portion, so that the sample flows through the channel from the inlet toward the outlet. The device for detecting micro particles in gas provides the advantage that micro particles included in gaseous sample can be detected without having to use additional pump or collector, detection time can be reduced, and detection accuracy can be improved.
