Abstract: Disclosed are conductive liquid metal microparticles including a hydrogen-doped liquid metal oxide, a conductive ink including same, and a preparation method therefor. The conductive liquid metal microparticle includes a core containing a liquid metal and a shell surrounding the core and containing a hydrogen-doped liquid metal oxide. Since the conductive ink includes the liquid metal microparticles, with the use of the conductive ink, it is possible to form a circuit line exhibiting metal conductivity, an insignificant change in resistance when deformation or mechanical damage occurs, stability of electric characteristics under extreme environment, and good adhesion to an elastic substrate.
