技術說明

本研究探討薄層壓力感測墊片、ZigBee 無線傳輸技術及應用程式管理系統整合之技術，以鈦酸鋇(Barium titanate)、鋯鈦酸鉛(Lead Zirconate titanate, PZT )及氧化鋅(Zinc Oxide)等材質，比較其具高電荷密度、低雜訊、輸出大、反應速度快、高抗干擾係數等性質，選擇並製作出可撓式壓力感測墊片，其後再對薄層壓電材質進行數據量測，同時以ZigBee 無線傳輸技術與伺服端程式，整合感應節點上所有作用在感測墊片之活動體狀態訊號與活動軌跡路徑狀況，並量測整合後系統傳輸距離、節點傳輸狀態、電源使用效能及抗干擾能力等，最後以所設計之可撓式壓力感測墊片，經由適當面積的鋪設進行各項動態訊號量測，再藉由程式設計與量測信號之分析，透過ZigBee之傳輸以聯繫手機等各項接收工具，達到無線互通之系統整合功能。 This project focuses on the measuring of piezoelectric material within thin layers by applying an integrating technology of flexible pressure sensing pads, ZigBee wireless transmission, and an applied programming management system. Materials, such as Barium titanate, Lead zirconate titanate, PZT, or Zinc Oxide, will be investigated elaborately to find out a suitable thin pressure sensor material, possessing high charge density, good noise immunity, large output gain, short response time, and high anti-interference ability. The server is applied to collect the data transmitted from Zigbee sensor network to track the path of moving object through the sensing nodes packaged in sensor pads. The transmitting range of the wireless system, topology of nodes, power effectiveness, and anti-interference ability will be measured. Finally, a suitable area built with flexible pressure sensor pads will be set up to emulate the moving objects and measure the dynamic signals.
