Abstract The terahertz metamaterial sensing system is an important application because of its attractive potential to identify and detect trace amounts of chemicals and biochemicals. However, most of the Terahertz metamaterials are made from bulk gold substrates using photolithography, which requires complex equipment and wastes expensive materials. We have developed a terahertz metamaterial using soft lithography with gold nanoparticles to overcome this limitation. The Terahertz metamaterial consists of gold nanoparticles and poly (3, 4-ethylenedioxy-thiophene) (PEDOT), which is prepared by imprinting and polymerizing the mixed solution using a patterned PDMS mold. We have introduced gold nanoparticles that are more precisely and sensitively tunable than bulk gold and have used conductive polymers that have no electrical resistance. Soft lithography can make highly sensitive terahertz metamaterials easier and cheaper. Furthermore, it is possible to fabricate various shapes and structures of terahertz metamaterials infinitely through various master patterns.
