Porous conductors with large surface-volume ratios have been applied to a variety of fields, including absorbents, flexible heaters,\nand electrodes for super capacitors. In this study, we implemented sensitive pressure sensors using the mechanical and electrical\ncharacteristics of conductive porous structures manufactured by immersing sponges into a carbon nano tube solution and then\nmeasured the change in resistance. When pressure was applied to conductive sponges, carbon nano tubes were attached to each\nother and the resistance was reduced by up to 20%. The carbon nano tube sponges, which were soft and had superior elasticity,\nwere quickly stabilized without any changes taking place in their shape, and they showed consistent change in resistance during\nexperiments of repetitive pressure. The pressure devices based on conductive porous sponges were connected to single-walled\ncarbon nano tube field effect transistors (SWCNT-FETs) and changes in their characteristics were investigated according to external\npressure.
