Research Abstract

The PI has developed elementary technologies for wireless structural vibration measurement systems with the future target of comprehending structural condition and behavior in detail. The technologies include : 1) elongation of communication distance by improving the antenna part of wireless sensor nodes, 2) data transfer using multihop communication, 3) the use of high resolution acceleration sensor boards, and 4) integrated program to perform synchronized sensing over a multihop network.
