Wearable devices provide an alternative pathway to clinical diagnostics by exploiting various physical, chemical, and biological sensors to mine physiological (biophysical and/or biochemical) information in real-time (preferably, continuously) and in a non-invasive or minimally invasive manner. These sensors can be worn in the form of glasses, jewelry, face masks, wristwatches, fitness bands, tattoo-like devices, bandages or other patches, and textiles. Wearables such as smartwatches have already proved their capability for the early detection and monitoring of the progression and treatment of various diseases, such as COVID-19 and Parkinson's disease, through biophysical signals. Next-gen wearable sensors that enable the multimodal and/or multiplexed measurement of physical parameters and biochemical markers in real-time and continuously could be a transformative technology for diagnostics, allowing for the high-resolution and time-resolved historical recording of the health status of an individual. In this Review, we examine the building blocks of such wearable sensors, including the substrate materials, sensing mechanisms, power modules, and decision-making units, by reflecting on the recent developments in the materials, engineering, and data science of these components.
