摘要： The present disclosure discloses a strain sensor and a method of fabricating the same. The strain sensor according to an embodiment of the present disclosure includes an X-axis sensor formed on a flexible insulating substrate and responsible for sensing X-axis strain; a Y-axis sensor formed on the flexible insulating substrate to be orthogonal to the X-axis sensor and responsible for sensing Y-axis strain; a metal electrode formed on a region of the flexible insulating substrate where the X-axis sensor and the Y-axis sensor are not formed; and an encapsulation layer formed on the X-axis sensor, the Y-axis sensor, and the metal electrode. In this case, the X-axis sensor and the Y-axis sensor have a metal-insulator heterostructure.

摘要： Disclosed is a patterning method by ink lithography. More particularly, the patterning method includes coating thin film-forming nanoparticles surrounded by the first ligand on a substrate to form a nanoparticle thin film; directly spraying a ligand-substituting ink to a selected region on the nanoparticle thin film to form a region in which the first ligand is substituted with the second ligand; and washing the nanoparticle thin film with a washing solvent so that the region substituted with the second ligand is patterned.

摘要： Disclosed are a method of directly patterning a stretchable substrate; and a stretchable electrode fabricated by the method. More particularly, the method of directly patterning a stretchable substrate includes: forming a hydrophilic group on a surface of a stretchable substrate by UV-ozone treatment; forming at least one layer to be etched on the hydrophilic group-formed stretchable substrate, wherein the at least one layer to be etched includes an adhesion enhancing material; forming a photoresist layer on the at least one layer to be etched; exposing the photoresist layer; and patterning the at least one layer to be etched using the exposed photoresist layer, wherein a carbon chain included in the adhesion enhancing material forms ether bonding (R—O—R) with a hydrophilic group formed on the surface of the stretchable substrate.
