Editorial for the Special Issue "Personal Health and Wellbeing Intelligent Systems Based on Wearable and Mobile Technologies"

Wearable and mobile personal devices, from smart phones, bands, glasses, and watches to smart clothes and implants, are becoming increasingly ubiquitous. These wearable sensing technologies can provide 24/7 physiological and movement data that enhance the knowledge base of users or groups of users. They constitute the internal fabric of an Internet of Smart Things, which provides the basis for better understanding the user—what the user does, when, how, and even why. Both physical and mental health-related information can be extracted or inferred from the diverse nature of the data. Sensor miniaturization and affordable prices are bridging the gap between theoretical health and wellbeing scenarios based on wearable technology and their feasible deployment on real settings. Personal health monitoring applications based on wearable sensors will empower the role of the user in its health self-management and will decrease the pressure of care-related resources for public health systems. Several medical conditions, from temporary illnesses to long-term chronic conditions, can benefit from the deployment of wearable sensors that monitor the user physiological parameters and physical activities on a continuous basis and provide automated feedback in real time to help each user in a personal way
