中文摘要 | 本文實現一個與CMOS製程相容之矽壓阻式微感測器訊號讀出電路與應用系統。本研究利用微感器搭配AT89C51微控制器及商用類比數位轉換器,完成廣用壓力計之研製;另外,整合矽壓阻式微感測器、血壓計零組件、個人電腦與圖控式程式語言(LabVIEW)進行血壓計量測訊號擷取,完成一可提供長期監測記錄之血壓計系統。廣用壓力計的量測範圍在-291mmHg-100mmHg,精確度為5mmHg。血壓計系統收縮壓平均誤差0.041'舒張壓平均誤差-0.075'精確度至lmmHg。本研究延伸了矽壓阻式微感測器於商用及醫用儀器之應用價值。 |
英文摘要 | This paper presents a readout circuit design and specific pressure system applications for silicon-based resistive type micro sensor in CMOS technology. Integrating with readout circuit, micro-controller AT89C51 and AlDconverter, the sensor has been used to develop a generic, portable mu1ti-purpose pressure meter. By interfacing with Si micro sensor, parts of commercial blood pressure meter,personal computer and virtual instrument LabVIEW, a prototype of blood pressure system has been realized for longterm monitoring usage. The measured range of generic pressure meter is from -291 to 100mmHg, and the accuracy is 5mmHg. The average sensitivity of blood pressure system is 0.041/-0.075 for systolic/diastolic measurements, and the accuracy is lmmHg. The research extends the values of silicon pressure sensor for consumer and biomedical instrumentalapplications. |
