  • Publication number: 20220149284
    Abstract: In a method for manufacturing conductive polymer electrode by using drop casting, a conductive material is dispersed in a solution, to form a first mixing solution. A first polymer is added and dispersed to the first mixing solution, to form a second mixing solution. A second polymer solution is added and dispersed to the second mixing solution, to form a third mixing solution. The third mixing solution is dropped on a hot plate using a pipette and a solution of the third mixing solution is evaporated, to form a conductive polymer. The adhesive patch is formed. The adhesive patch is attached to the conductive polymer.

  • Patent number: 11056339
    Abstract: In a thin film electrode separation method using thermal expansion coefficient, a first solution is coated on a substrate. The first solution coated on the substrate is hardened. The substrate is left in a predetermined time, to form a first thin film having a first thermal expansion coefficient on the substrate. A photoresist is coated on the substrate having the thin film formed thereon. The photoresist coated on the substrate is hardened, to form a photoresist film having a second thermal expansion coefficient. A metal and a passivation layer are formed on the photoresist film. The photoresist film is detached from the first thin film, using difference of a thermal expansion coefficient between the photoresist film and the first thin film.
