We have investigated human-stress monitoring by making use of salivary nitrate, which can be a candidate for stress markers, with ion-selective field-effect transistors (ISFETs). ISFETs are suitable for on-site single-drop analysis of salivary nitrate within 10 s. However, when ISFETs are used for salivary nitrate, ISFETs have a problem that is called the initial drift. The initial drift makes accurate nitrate monitoring difficult. Thus, the purpose of this study is to prevent the initial drift and to search for a new, simple polymer to possess a better performance of sensor responses than conventional matrix membranes, such as PVC. In this research, we investigated ISFETs using specific matrix membranes, for example KP-13, Pellethane®­­, and P7281-PU. The initial drift was evaluated from the fluctuations of the response values generated by the ISFETs when immersed in saliva or aqueous solution. As a result, P7281-PU showed a prevention effect on the initial drift, both in the whole saliva and in various solutions. Furthermore, the cause of drift may be H+ diffusion, and the drift prevention effect of P7281-PU may be affected by urethane bond capturing H+ in the ion-selective membrane. This result suggests that a continuous nitrate monitoring is feasible and may be applied to wearable sensors.

Buried Gas Pipeline

The ground settlement caused by high-rise buildings is prominent increasingly with the rapid development of city construction, and will have negative influence on the surrounding gas pipelines. In this paper, an on-site monitoring system for settlement and stress-strain of buried gas pipeline is established, located in the neighboring area of Shanghai Center Tower, which is being built and will be the tallest building in china. The continuous online, real-time monitoring of stress changes and pipeline settlement can be realized. With the system of GPRS automatically data acquisition and wireless remote transmissions are achieved. Field test testify the effectiveness of the system, also shows that significant settlement and strain exist in the test pipe, and long-time monitoring and analysis is needed
