Item Unknown Carbon-based nanomaterials and sensing tools for wearable health monitoring devices(Wiley-VCH Verlag GmbH & Co. KGaA, 2021-10-05) Erdem, Özgecan; Derin, Esma; Shirejini, Saeedreza Zeibi; Sağdıç, Kutay; Yılmaz, Eylül Gülşen; Yıldız, Selvin; Akçeoğlu, Garbis Atam; İnci, FatihThe healthcare system has a drastic paradigm shift from centralized care to home-based and self-monitoring strategies; aiming to reach more individuals, minimize workload in hospitals, and reduce healthcare-associated expenses. Particularly, wearable technologies are garnering considerable interest by tracking physiological parameters through motion and activities, and monitoring biochemical markers from sweat, saliva, and tears. Through their integrations with sensors, microfluidics, and wireless communication systems, they allow physicians, family members, or individuals to monitor multiple parameters without any significant disruptions to daily routine. Integrating flexible and smart materials with wearable platforms have already enabled facile operations. Especially, carbon nanomaterials hold unique features, including low density, high strength, good conductivity, outstanding flexibility, versatile integration with materials and sensors. In this manuscript, carbon nanomaterials are comprehensively reviewed with their tremendous assets utilized in wearable technologies. Further, their integration with ultrasonic, acoustic and energy harvesting devices, optical and electrochemical platforms, microfluidics, and wireless communication technologies are presented.Item Unknown Skin-patchable electrodes for biosensor applications: A review(American Chemical Society, 2020) Shetti, N. P.; Mishra, Amit; Basu, S.; Mascarenhas, R. J.; Kakarla, R. R.; Aminabhavi, T. M.Health care monitoring is an extremely important aspect of human life that can be accomplished using wearable skin-patchable sensors. Upon interfacing with the skin or epidermal surface of the body, the sensing patches can monitor the movements of human parts such joints, legs, and fingers as well as tiny vibrations caused by respiration, blood flow, and heart beat. Wearable skin patches have shown improved promise in monitoring the body temperature and fever in addition to quick measurement of blood pressure and pulse rate along with breathing rate. Sensors can also analyze the sweat contents when in contact with the skin as well as other analytes such as diabetes-based volatile organic compounds (VOCs) and organophosphate nerve stimulating agents. Hence, the sensors can be of immense help in the early prediction of malfunctions of the body organs such as heart and lungs, leading to timely and effective treatment. This review covers different important aspects of skin-patchable sensors including mechanical strength and flexibility, sensitivity, transparency, self-healing, self-cleaning, and self-powering ability as well as their latest applications in medical technology.
