3D-printed stretchable modular integrated microsystems toward sweat monitoring powered by wireless charging sodium-ion micro-batteries.

ABSTRACT: The emerging development of energy storage integrated microsystems plays a pivotal role in advancing flexible and wearable electronics, yet their compatible construction and stretching robustness remain unsolved. Herein, we report an all three-dimensional (3D) printing construction of a stretchable modular integrated microsystem, composed of wireless receiving coils, aqueous sodium-ion micro-batteries (ASMBs) and glucose sensors. A versatile binder-free graphene-based ink is developed to largely reduce the construction complexity and boost compatibility between multiple modules. The resulting 3D-printed ASMBs exhibit high areal capacity of 0.96 mAh cm^-2, favorable stability after 1500 cycles and uniformity of integration, profited from the elaborately designed microelectrodes wi
