Abstract

See full text

A method for producing a micro-pattern on surface of a wire is disclosed. The method includes a step of applying a nanoparticle solution to the wire to form a nanoparticle solution layer on the surface of the wire; and a step of irradiating the nanoparticle solution layer with a Bessel beam laser to induce sintering of nanoparticles, thereby forming a micro-pattern on the surface of the wire. It is possible to form a microelectrode pattern on a level of several to tens of micrometers on the surface of a micro-wire having a diameter on a scale of several tens to several hundreds of micrometers. Since a laser optical system with a long depth of focus is used, a micro-pattern with a uniform thickness can be formed on surface of a wire having a curvature in a simple.
