Abstract
The evolution of wearable technology has prompted the need for adaptive, self-healable, and energy-autonomous energy devices. This study innovatively addresses this challenge by introducing an MXene-boosted hydrogel electrolyte, which expedites the assembly process of flexible thermocell (TEC) arrays and thus circumvents the complicated fabrication of typical wearable electronics. Our findings underscore the hydrogel electrolyte's superior thermoelectrochemical performance under substantial deformations and repeated self-healing cycles. The resulting hydrogel-based TEC yields a maximum power output of 1032.1 nW under the ΔT of 20 K when being stretched to 500% for 1000 cycles, corresponding to 80% of its initial state; meanwhile, it sustains 1179.1 nW under the ΔT of 20 K even after 60 cut-healing cycles, approximately 92% of its initial state. The as-assembled TEC array exhibits device-level self-healing capability and high adaptability to human body. It is readily applied for touch-based encrypted communication where distinct voltage signals can be converted into alphabet letters; it is also employed as a self-powered sensor to in-situ monitor a variety of body motions for complex human actions. The swift assembly approach, combined with the versatile functionality of the TEC device, paves the way for future advancements in wearable electronics targeting at fitness monitoring and human-machine interfaces.

Abstract
INTRODUCTION Traditional therapy methods for treating tuberculous bone defects have several limitations. Furthermore, systemic toxicity and disease recurrence in tuberculosis (TB) have not been effectively addressed. AREAS COVERED This review is based on references from September 1998 to September 2021 and summarizes the classification and drug-loading methods of anti-TB drugs. The application of different types of biological scaffolds loaded with anti-TB drugs as a novel drug delivery strategy for tuberculous bone defects has been deeply analyzed. Furthermore, the limitations of the existing studies are summarized. EXPERT OPINION Loading anti-TB drugs into the scaffold through various drug-loading techniques can effectively improve the efficiency of anti-TB treatment and provide an effective means of treating tuberculous bone defects. This methodology also has good application prospects and provides directions for future research.
