Abstract:	結構在受疲勞或是地震作用下會產生裂縫，初期的裂縫對結構的影響並不顯著，然而隨著裂縫加大或是深度加深，外部的水氣會沿著裂縫進入結構內部造成鋼筋鏽蝕進而影響結構的安全。結構裂縫造成之滲水會影響隧道及混凝土壩等基礎設施的安全，而核廢料等高放射性廢棄物的儲存設施的洩漏更會造成環境的污染甚至危及性命安全。因此，若能在裂縫發生初期即可感知微弱的溼氣或是滲漏，即可提前預警，進行及時處置。本計畫整合氧化石墨烯與主被動無線技術研發一個可分層、分散内嵌於結構物內部，使其具有智慧滲漏感知的物聯網，利用新的被動式無線感測元件可在裂縫發生初期即可感知微弱的溼氣或是滲漏。本研究計畫預計以三年的時間完成所提出之研究內容。第一年主要目標為開發被動式氧化石墨烯智慧無線濕度感測元件。第二年主要目標為驗證第一年所研發之感測元件在埋入結構內之相關特性測試。第三年目標為整合前兩年的研發成果，並將被動式感測元件與主動式低功耗長距離無線傳輸技術整合成一個完整的物聯網系統，並進行現地安裝驗證。 ;Earthquake or fatigue can cause cracks in the structure. The initial cracks have no significant effect on the structure. However, as the cracks increase or the depth deepens, external moisture will enter the structure through the cracks and cause corrosion of the steel bars. Water seepage caused by structural cracks will affect the safety of infrastructures such as tunnels and concrete dams. Leakage of high-level radioactive waste storage facilities such as nuclear waste will cause environmental pollution and even endanger life safety. Therefore, this project integrates graphene oxide and active-passive wireless technologies to develop an IoT-based smart water seepage detection system. The smart sensor can layer, decentralized embedded in the structure to detect weak moisture or leakage at the initial stage of the crack. The project is expected to be completed within three years. The first year's main goal was to develop passive wireless graphene oxide-based smart wireless humidity sensing devices. The second year's main goal is to verify the relevant characteristics of the sensing element developed in the first year in the embedded structure. The third year aims to integrate the results of the previous two years and integrate passive sensing elements with low-power long-distance wireless transmission technologies into a complete IoT system and perform field verification.
