In this work, a facile strategy is proposed to construct stretchable electronics based on agarose hydrogels. The hot agarose solution is casted onto a template with patterned Ag nanowires, endowing agarose hydrogel with patterned conductive surface. After further heating treatment, Ag nanowires can be embedded into the agarose hydrogel, which improves the stability of Ag pattern and has no obvious effect on the conductivity of hydrogels. The agarose hydrogel with patterned Ag nanowires is certified to be an effective stretchable electrode to record the motion of joints, which has great potential applications in the field of wearable devices.

带有图案化银纳米线的琼脂糖水凝胶用于运动传感器的制备

在这项工作中，提出了一种简便的策略来构建基于琼脂糖水凝胶的可拉伸电子器件。将热的琼脂糖溶液浇铸到具有图案化的Ag纳米线的模板上，使琼脂糖水凝胶具有图案化的导电表面。经过进一步加热处理后，可以将Ag纳米线嵌入琼脂糖水凝胶中，提高了Ag图案的稳定性，对水凝胶的电导率没有明显影响。带有图案化银纳米线的琼脂糖水凝胶经认证是记录关节运动的有效可拉伸电极，在可穿戴设备领域具有巨大的潜在应用。
