Wearable devices have found numerous applications in healthcare ranging from physiological diseases, such as cardiovascular diseases, hypertension and muscle disorders to neurocognitive disorders, such as Parkinson’s disease, Alzheimer’s disease and other psychological diseases. Different types of wearables are used for this purpose, for example, skin-based wearables including tattoo-based wearables, textile-based wearables, and biofluidic-based wearables. Recently, wearables have also shown encouraging improvements as a drug delivery system; therefore, enhancing its utility towards personalized healthcare. These wearables contain inherent challenges, which need to be addressed before their commercialization as a fully personalized healthcare system. This paper reviews different types of wearable devices currently being used in the healthcare field. It also highlights their efficacy in monitoring different diseases and applications of healthcare wearable devices (HWDs) for diagnostic and treatment purposes. Additionally, current challenges and limitations of these wearables in the field of healthcare along with their future perspectives are also reviewed.

可穿戴设备已在医疗保健中找到了许多应用，从诸如心血管疾病，高血压和肌肉疾病等生理疾病到诸如帕金森氏病，阿尔茨海默氏病和其他心理疾病的神经认知障碍。为此目的使用不同类型的可穿戴设备，例如基于皮肤的可穿戴设备，包括基于纹身的可穿戴设备，基于纺织品的可穿戴设备和基于生物流体的可穿戴设备。最近，可穿戴设备作为药物输送系统也显示出令人鼓舞的改进。因此，增强了其对个性化医疗的效用。这些可穿戴设备包含固有的挑战，在将其作为完全个性化的医疗保健系统商业化之前，需要解决这些挑战。本文回顾了当前在医疗保健领域中使用的不同类型的可穿戴设备。它还强调了它们在监控各种疾病以及医疗可穿戴设备（HWD）的诊断和治疗目的中的功效。此外，还回顾了这些可穿戴设备在医疗领域的当前挑战和局限性，以及它们的未来前景。
