| Abstract | Work currently being conducted under the NSF award entitled "Multi-scale Smart Sensing for Monitoring Civil Infrastructure" at the University of Illinois at Urbana-Champaign involves the development of a wireless smart sensor which can be used in a sensor network to quickly and accurately assess structural condition. Structural health monitoring (SHM) is a rapidly growing area of research in the field of Civil Engineering. Smart sensors incorporate wireless communication ability and on-board computational capacity and memory. These features allow a network of such smart sensors to aggregate and process data thus providing only pertinent information on the condition of a structure in almost real-time. Prof. Tomonori Nagayama at University of Tokyo has spent several years working with smart sensors for SHM applications and has pioneered efforts to use the Imote2 (a wireless sensor platform developed by Intel) for structural monitoring and damage detection. Jennifer Rice, a Ph.D. student from the University of Illinois traveled to the Bridge and Structures Laboratory at the University of Tokyo to work with Prof. Nagayama as well as Prof. Yozo Fujino, an expert in long span bridges. The goal of the research conducted at the University of Tokyo was to allow Jennifer to learn more about both the hardware and software involved in developing a wireless sensor network for SHM applications. In particular, she became familiar with the coding required to realize reliable communication within a network, synchronized sensing, system identification, and damage detection. She also received guidance on the design of a new multi-scale sensor board for SHM that interfaces with the Imote2. In addition, she and Prof. Nagayama set goals for future collaboration to accomplish multi-hop communication in a smart sensor network. Jennifer was also able to meet with industry leaders in Japan to discuss SHM practices, particularly in relation to seismic loading. She was an active member of her host laboratory, participating in meetings and giving research presentations. She participated in a number of technical site visits to various state-of-the art structures throughout Japan thus allowing her to see many parts of the country. In summary, the experience that Jennifer gained while in Japan will further the research being conducted at UIUC on smart sensors by allowing her to draw upon the experience of her collaborators at the University of Tokyo. In turn, Jennifer can pass on her knowledge to her colleagues in the U.S. where there is increasing realization of the necessity for effective monitoring of civil infrastructure. |

| Bio | B.F. Spencer, Jr. holds a B.S. in Mechanical Engineering (University of Missouri - Rolla 1981), and M.S. and Ph.D. in Theoretical and Applied Mechanics (University of Illinois at Urbana-Champaign 1983, 1985). He joined the faculty of the department of Civil and Environmental Engineering at the University of Illinois in 2002. Dr. Spencer served as a professor at the University of Notre Dame from 1985-2002. Dr. Spencer has research interests primarily in the areas of stochastic fatigue, stochastic computational mechanics, earthquake engineering, damage detection and health monitoring, and civil engineering applications of smart structures technology. He is currently a member of the executive board of the Asia-Pacific Network of Centers for Research on Smart Structures Technologies (ANCRSST). Dr. Spencer is a member of the American Society of Civil Engineers, the Earthquake Engineering Research Institute, the International Association for Structural Control, and the International Association for Structural Safety and Reliability. He was the founding chair of the Committee on Structural Control and is the past chair of the Committee on Fatigue and fracture Reliability, both in the ASCE Structures Division. He serves as associate editor of Shock and Vibration, is on the editorial board of the Journal of Structural Control, and has served as associate editor for ASCE Journal of Structural Engineering. Jennifer Rice is pursuing her Ph.D. in Civil Engineering from the University of Illinois at Urbana-Champaign (UIUC). She received her undergraduate degree in Civil Engineering from Texas Tech University in 2003 where she also conducted research in the Wind Science and Engineering Department. Jennifer then came to UIUC to pursue a graduate degree. She completed her Masters degree in 2005 under the supervision of Prof. Doug Foutch. Her Masters research focused on monitoring aluminum highway sign structures for the Illinois Department of Transportation (IDOT). She gained experience in full scale testing, structural modeling and also examined strategies for vibration mitigation using non-linear passive damping devices. Currently, Jennifer is developing an integrated, multi-scale sensor board to be used with the Imote2 that will facilitate the high resolution and low-noise measurements required for effective structural health monitoring. |
