Special Issue Information

Dear Colleagues,

Artificial skin, also known as electronic skin (e-skin), refers to intelligent wearable electronics that simulate the tactile perception function of human skin to identify the detected external information changes through different electrical signals. Flexible e-skin can achieve a wide range of functions, such as the accurate detection and identification of pressure, strain, and temperature, which has greatly extended their application potential in the field of healthcare monitoring and human-machine interaction. At present, the current study on flexible tactile sensors is developing towards high resolution, high sensitivity, self-powering, visualization, biodegradability, and self-healing. However, considering the urgent demand and rapid application of flexible sensing technology in various emerging applications, there remains a great challenge in how to achieve quantification, multi-function, high stability, and durability in the actual detection process. This topic provides an excellent opportunity for those who are studying and working on the design and applications of wearable electronics. Research papers, review articles, and communications relating to the material development, structural design, mechanism interpretation, preparation process, and related circuit design of artificial skins are all invited to this Topic.

Biological information detection technology is mainly used for the detection of physiological and biochemical parameters closely related to human tissues and organ lesions, such as biomarkers. This technology has important value in the clinical diagnosis and treatment of chronic diseases in their early stages. Wearable biosensors can be integrated with the Internet of Things and Big Data to realize the detection, transmission, storage, and comprehensive analysis of human physiological and biochemical information. This technology has extremely wide applications and considerable market prospects in frontier fields including personal health monitoring, chronic disease diagnosis and management, and home medical care. In this review, we systematically summarized the sweat biomarkers, introduced the sweat extraction and collection methods, and discussed the application and development of epidermal wearable biosensors for monitoring biomarkers in sweat in preclinical research in recent years. In addition, the current challenges and development prospects in this field were discussed. Full article

The current physical health care system has gradually evolved into a form of virtual hospitals communicating with sensors, which can not only save time but can also diagnose a patient’s physical condition in real time. Textile-based wearable sensors have recently been identified as detection platforms with high potential. They are developed for the real-time noninvasive detection of human physiological information to comprehensively analyze the health status of the human body. Sweat comprises various chemical compositions, which can be used as biomarkers to reflect the relevant information of the human physiology, thus providing references for health conditions. Combined together, textile-based sweat sensors are more flexible and comfortable than other conventional sensors, making them easily integrated into the wearable field. In this short review, the research progress of textile-based flexible sweat sensors was reviewed. Three mechanisms commonly used for textile-based sweat sensors were firstly contrasted with an introduction to their materials and preparation processes. The components of textile-based sweat sensors, which mainly consist of a sweat transportation channel and collector, a signal-selection unit, sensing elements and sensor integration and communication technologies, were reviewed. The applications of textile-based sweat sensors with different mechanisms were also presented. Finally, the existing problems and challenges of sweat sensors were summarized, which may contribute to promote their further development. Full article
