2016 IEEE. Technological advances in biomedical engineering have significantly improved the quality of life and increased the life expectancy of many people. One component of such advanced technologies is represented by wireless in vivo sensors and actuators, such as pacemakers, internal drug delivery devices, nerve stimulators, and wireless capsule endoscopes (WCEs). In vivo wireless body area networks (WBANs)and their associated technologies are the next step in this evolution and offer a cost-efficient and scalable solution along with the integration of wearable devices. In vivo WBAN devices are capable of providing continuous health monitoring and reducing the invasiveness of surgery. Furthermore, patient information can be collected over a longer period of time, and physicians are able to perform more reliable analysis by exploiting this big data rather than relying on the data recorded in short hospital visits.
