摘要

可穿戴技术的发展促进了对自适应、自我修复和能源自主的能源设备的需求。本研究通过引入一种mxene推进的水凝胶电解质，创新地解决了这一挑战，该电解质加速了柔性热电池(TEC)阵列的组装过程，从而绕过了典型可穿戴电子产品的复杂制造。我们的发现强调了水凝胶电解质在大量变形和重复自愈循环下优越的热电化学性能。所得的水凝胶基TEC在ΔT温度为20 K的条件下，当拉伸到500%，循环1000次时，其最大功率输出为1032.1 nW，相当于其初始状态的80%;同时，在ΔT 20 K条件下，即使经过60次切割愈合循环，其仍能维持1179.1 nW，约为初始状态的92%。组装后的TEC阵列具有设备级自修复能力和对人体的高适应性。它很容易应用于基于触摸的加密通信，其中不同的电压信号可以转换为字母;它也被用作自供电传感器，用于现场监测各种复杂的人体动作。快速组装方法，结合TEC设备的多功能，为未来可穿戴电子产品的发展铺平了道路，目标是健身监测和人机界面。

Swift Assembly of Adaptive Thermocell Arrays for Device-Level Healable and Energy-Autonomous Motion Sensors

Highlights

The MXene-boosted rapid gelling expedites the assembly of flexible thermocell arrays, overcoming the typical constraint of complicated device fabrication processes.
The hydrogel electrolyte can sustain stable thermoelectrochemical performance under various challenging conditions, including large, repeated, and sustained deformations, and multiple cut-healing cycles.
The as-assembled thermocell array exhibits device-level self-healing capability and high adaptability to human body, efficiently harvesting low-grade heat for wearable applications.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
