Figure 6. Bio-absorbable (or -degradable) BMSCs. (A) Schematic illustration of a planar-type supercapacitor consisting of biodegradable metal thin-film (W, Fe, or Mo) electrodes and a NaCl/Agarose gel electrolyte on a glass substrate^[61]; (B) Diagram of the biodegradable serpentine-shaped wire supercapacitor and cycle stability during bending deformation tests^[100]; (C) Structure and degradation absorption diagram of the bio-degradable and bio-absorbable micro-supercapacitor^[156]; (D) Schematic illustration of the fabrication and degradation tests of the thin, high-performance bio-degradable and bio-absorbable MSC, and the results of degradation/absorption in vitro and in vivo^[60].
