Radio frequency identification (RFID) has been utilized to increase efficiency and care quality in hospitals for patient information management, drug and equipment inventory, scheduling, and staffing. To further improve healthcare while aiming to reduce costs, major technical challenges still exist. Limited sampling and acquisition of physiological parameters during the interaction between caregivers and patients provide incomplete information about the patients. Better care with higher diagnosis accuracy can be provided if more and timelapsed data can be obtained without causing patients discomfort or limiting their mobility. Meanwhile, patient data documentation has become too cumbersome. The lack of portability and accessibility of the physiological information prevent real-time management by caregivers and patients themselves.
This lecture focuses on the development of wireless micro devices and systems for clinical and biological applications. The systems are based on technology such as wireless energy transfer for batteryless implants, miniature electrochemical sensors, nanoparticle modified surfaces, microelectromechanical systems and microwave communication. In this talk, several implantable wireless diagnosis and therapeutic treatment systems will be discussed. An integrated wireless body network for chronic pain management has been demonstrated with wireless closed-loop integration of neurorecorders to recognize pain signals and neurostimulators to inhibit pain. Batteryless disease (GERD), an endoscopically-implantable wireless gastro-stimulator for gastroparesis management, and a wireless bladder volume monitoring implant for urinary incontinence management. These applications enable new medicines to improve human welfare and assist better living.
BIOGRAPHY J.C. Chiao received his Ph.D. degree at California Institute of Technology in 1995, and served as a Research Scientist at Bell Communication Research, Assistant Professor at University of Hawaii, and Product Line Manager and Senior Technology Advisor at Chorum Technologies from 1996 to 2002. He joined UTA as an Associate Professor in 2002. He is now a Jenkins Garrett Professor of Electrical Engineering and Joint Biomedical Engineering Program at University of Texas - Arlington; and an Adjunct Associate Professor in the Internal Medicine Department at UT-Southwestern, Medical Center. Dr. Chiao is a senior member of IEEE. He has published numerous peer-reviewed papers, edited several proceedings and books, and chaired several international conferences. He obtained five awarded and six pending patents. He received the 2011 O'Donnell Award in Engineering presented by The Academy of Medicine, Engineering and Science of Texas (TAMEST). He also received the 2011 Dallas Fort Worth Metroplex Technology Business Council Tech Titan Technology Innovator Award, and 2011 Lockheed Martin Aeronautics Company Excellence in Engineering Teaching Award.
