The advancement in sensing, embedded computing, and wireless communication has accelerated the progress of Body Area Networks (BodyNets). BodyNets integrate and deploy wireless sensors, RFID tags, and other pervasive devices within and around human bodies for constructing diverse and practical systems for smart health and wellbeing, human computer interaction, and provision of entertainment. This conference will explore the challenges and technical approaches to designing, building, and deploying BodyNets. The conference aims to establish a forum to exchange ideas, discuss practices, raise awareness, and to share cutting edge technology and experiences among researchers and practitioners in the field of computer science, biomedical engineering, medicine, and other disciplines in both academia and industry.
