Conceptual illustration of a laser-induced temperature-tolerant film without additional anti-oxidative encapsulations for sensing in extreme environments (IMAGE)
Caption
(a) Schematic of the proposed laser-induced double-layer films compared to the conventional thermal sintering. (a-i) Schematic of the material and morphology of the film before and after laser direct writing. (a-ii) Schematic of the oxidized film caused by conventional thermal sintering. (a-iii) Schematic of the wide detection range of temperature for the proposed film-based temperature sensor. (b) Schematic of the formation process of continuous and uniform TiB2 conductive traces using laser-induced sintering. The left and center insets denote the ease of electron migration before and after laser processing, respectively. (c) Schematic of the production of an anti-oxidative glassy protective phase during laser-induced passivation. The right and center insets denote the difference in the ease of oxygen penetration before and after laser processing, respectively.
