Wearable heaters have attracted broad attention due to their applications in personal heating systems and healthcare management, such as heat preservation in textile/clothing and thermotherapy. Protecting heating performance against deterioration under large deformation is is important for the application of wearable heaters. Here, a highly stretchable electrically driven heater based on electrically conductive weft‐knitted fabrics is reported, which can be transformed from traditional fabrics through a facile heat treatment process. As an example, a heater made from Modal shows a heating temperature higher than 100 °C at a driving voltage as low as 3 V. The Joule heating performance of the heater does not deteriorate even under a large strain of 70%. Furthermore, according to theoretical analysis and experimental results, the output power and saturated temperature of the heater under a certain voltage can be easily tuned by tailoring the shape and size of the fabric to meet customized demands. The superior performance of the heater originates from the weft‐knitted structural configuration. Finally, the application of the ultrastretchable heater in wearable thermal therapy devices is demonstrated, showing its great potential in wearable electronics.

高伸缩性和低压可穿戴加热器的纬编织物
穿戴式加热器由于其在个人供暖系统和医疗保健管理中的应用而受到广泛关注，例如在纺织品/衣服中的保温和热疗。保护加热性能免于大变形下的劣化对于可穿戴加热器的应用很重要。此处报道了一种基于导电纬编织物的高度可拉伸的电动加热器，可通过简便的热处理工艺将其从传统织物中转化出来。例如，由莫代尔（Modal）制造的加热器在低至3 V的驱动电压下显示出高于100°C的加热温度。即使在70％的大应变下，加热器的焦耳加热性能也不会降低。此外，根据理论分析和实验结果，通过调整织物的形状和尺寸以满足定制需求，可以轻松调整加热器在一定电压下的输出功率和饱和温度。加热器的卓越性能源于纬编结构构造。最后，展示了超拉伸加热器在可穿戴热疗设备中的应用，显示了其在可穿戴电子产品中的巨大潜力。
