Remotely Powered Arrays of Active Strain-Gauge Wall Sensors Project Description

这是一个SGER项目，旨在探索大型应变片阵列遥感的可能性，这些应变片阵列可以嵌入建筑物墙壁和桥梁中，用于连续或按需监测结构的健康状况。 将研究由有源模拟超大规模集成电路晶体管化电桥电路组成的芯片的功率处理能力，它决定了应变片的状态。最初，商业上可获得的应变片产品将被用作有源电桥中的一个臂，该有源电桥将被送到mosis制造成超大规模集成电路芯片。 还应确定钢筋混凝土等结构材料的衰减特性，以及将数据传入和传出嵌入式桥梁的方法。 作为初步的概念验证，远程系统将安装在墙壁的外部，而更长距离的研究将把它嵌入墙壁内部。

This is a SGER project to explore the possibility of remote sensing of large strain gauge arrays, which may be embedded in building walls and bridges, for continuous or on-demand monitoring of the structure's healthcondition. The power handling capabilities of a chip consisting of active analog vlsi transistorized bridge circuits,which determines the state of the strain gauge will be investigated, Initially the commercially availablegauge products will be used as an arm in the active bridge that will be sent to mosis for fabrication into a vlsi chip. The attenuation characteristics of structural materials such as reinforced concrete are also to be determaned as well ass a means of transmitting data into and out of the embedded bridge. As a preliminary proof of concept the remote system will be mounted on the exterior of a wall whereas longer range studieswill incorporate it embedded inside of walls.
