This research is emphasized particularly on cathodes (such as carbon, metal oxides, MXenes, and redox-active polymers), anodes (such as Zn-based composite materials and Zn-free materials), electrolytes (organic/ionic liquid electrolytes, WiSs, redox electrolytes, polymer or solid electrolytes) as well as the design of a novel device for ZHSCs.

Despite years of exploration, numerous challenges remain unresolved in the field of hydrogels and hydrogel membranes for bone repair. In this review, we provide a comprehensive overview of the fundamental principles and current development status of hydrogel materials for bone repair, including their mechanisms, formation principles, and medical benefits in bone regeneration. Additionally, we summarize recent effective strategies to develop advanced hydrogels and technical approaches for bone repair while also discussing future directions.

Wearable devices provide an alternative way to clinically diagnose respiratory diseases in a non-invasive and real-time manner. In this review, we summarize the recent developments in the field of wearable respiratory sensors, including the methods to synthesize various sensing materials, the ways to improve respiratory sensing performances, and the feature comparison among different sensing materials. We also summarize the concentrations, sources and associated diseases of various biomarkers in exhaled gas. Finally, we discuss current trends in the field to provide predictions for the future trajectory of wearable respiratory sensors.

Biomaterial fabrication techniques and therapeutic strategies for spinal cord injury. This review focuses on the most recent advancements of biomaterial-based therapeutics for the treatment of spinal cord injury. The outer ring of the figure shows four fabrication techniques for tissue engineering: hydrogel, electrospinning, 3D printing and decellularization. The inner ring shows the injured spinal cord and the roles of biomaterials in spinal cord injury repair, for instance, restoring the blood‒spinal cord barrier (BSCB).
