2 Research context Tutor: Prof. Oreste Andrisano Co-Tutor: Prof. Roberto Verdone Reasearch activity performed in the framework of: European Integrated Project WiserBAN Cost Actions: IC1004 2
3 Introduction WBAN = Wireless Body Area Network Collection of nodes placed on, or optionally inside, the human body Sensing and communication capabilities Applications Medical: monitoring vital parameters, drug delivery, implants, hearing aids Sport/Fitness: rehabilitation, motion capture, monitoring parameters Entertainment: consumer electronics (audio/video streaming, interactive gaming), personal item tracking 3
4 WBAN applications: WiserBAN Use Cases Audio streaming Binaural audio link Digital Audio Audio Streaming Implanted part Telephony Remote control «behind-the-ear» to «in-the-ear» Remote control Clinical Fitting FMT Floating Mass Transducer or Cochlear Implant multichannel electrode Hearing aids Cochlear Implant Glucometer Internet PC Remote control Insulin pump Cardiac Implants 4 Insulin Pumps
