Pursuit of improved living quality has stimulated great demand for high-performance conformal healthcare devices in modern human society. However, manufacturing of efficient, comfortable and stretchable biomedical apparatus faces huge challenges using traditional materials. Liquid metals (LMs) show remarkable potential to solve this problem due to their extraordinary biocompatibility, stretchability, thermal and electrical conductivity. In recent years, tremendous explorations have attempted to make stretchable biomedical devices with LMs. Herein, we review the stretchable LM-based biomedical devices on the topics of disease treatment and human function augmenting. The representative and up-to-date neural interfaces, alloy cement, e-vessels, soft heaters, exoskeletons, and e-skins are summarized. The existing issues of LMs applied for biomedical devices are also discussed. This review can provide guidance for the follow-up research in LM-based biomedical devices.

现代人类社会对提高生活质量的追求激发了对高性能适形医疗器械的巨大需求。然而，使用传统材料制造高效、舒适和可拉伸的生物医学器械面临着巨大的挑战。液态金属（LM）由于其非凡的生物相容性、拉伸性、导热性和导电性而显示出解决这一问题的巨大潜力。近年来，人们尝试用 LM 制造可拉伸的生物医学设备。在此，我们回顾了基于 LM 的可拉伸生物医学设备，其主题是疾病治疗和人类功能增强。总结了具有代表性和最新的神经接口、合金水泥、电子容器、软加热器、外骨骼和电子皮肤。还讨论了语言模型应用于生物医学设备中存在的问题。该综述可为基于LM的生物医学设备的后续研究提供指导。
