Abstract:
The present invention relates to a flexible energy conversion device using a liquid, and more specifically, to a method and a device for converting mechanical energy into electric energy by applying an opposite phenomenon of electrowetting, which can change a surface contacting the liquid between one pair of electrodes, and use the change of the surface contacting the liquid to generate electric energy, so as to prevent channel blocking or so that a lubricating layer or electrodes patterned onto a channel in a complicated manner are not required, thereby enabling simplification of the device, reduction of manufacturing cost, and the energy conversion device that is less faulty.
Abstract:
Disclosed is a reflective display device for visible light and infrared camouflage and an active camouflage device using the same, the reflective display device including: an upper substrate formed of a transparent material; an upper electrode layer formed of a transparent material provided under the upper substrate; at least one unit cell provided under the upper electrode layer, the unit cell containing a fluid and multiple particles being charged with opposite polarities and having different quantities of electric charge or different sizes; a lower electrode layer provided under the unit cell, the lower electrode layer for generating an electric field in conjunction with the upper electrode layer and defining a pixel area; a metal layer provided under the lower electrode layer, the metal layer blocking thermal-infrared rays; and a lower substrate provided under the metal layer.
Abstract:
A device for measuring a penetration rate of outdoor air including humidity or oxygen of a material, and a reaction material cartridge for measuring an outdoor air penetration rate. The device includes a reacting part including a reaction material which reacts upon contact with outdoor air passing through a substrate; a cartridge body which accommodates the reaction part, and which is detachable from a measuring unit for measuring a change corresponding to the contact of the reaction material with the outdoor air; and a shielding means which shields the cartridge body, and which is separated from the cartridge body for contact between the reaction material and the outdoor air.
