低成本地下水感應器
普渡大學推出3D打印地下水感應器
普渡大學（Purdue University）一名研究人員，推出一款正在申請專利、以 3D 打印製造的地下水感應器，設計旨在以遠低於專業替代方案的成本，監測地下水流動的速度及方向。此裝置由 Jacob Hosen 及 Zaven Arra 研發，僅需數百美元，即可透過實驗室打印的外殼及配備溫度感應器陣列的電路板製成。
此紋理外殼設計旨在重現周遭的土壤環境，同時不干擾自然水流。相關組件可於實驗室內部組裝，無需依賴外部製造，可實現快速設計調整。此感應器透過 LoRa 網絡以無線方式傳輸數據，同時於本機儲存資料作為備份，初步測試顯示其可於水下持續運作七至八個月。
對研究人員及環保機構而言，此低成本設計，有助支持對地下水流動、污染及濕地水文更分散式的監測工作。研究團隊正尋求專利保護，以維持此技術原定的開源公開使用理念。
英文原文
A Purdue University researcher introduced a patent-pending, 3D-printed groundwater sensor designed to monitor the speed and direction of subsurface water movement at a fraction of the cost of specialized alternatives. Developed by Jacob Hosen and Zaven Arra, the device can be produced for a few hundred dollars using lab-printed housings and circuit boards equipped with arrays of temperature sensors.
The textured housing is designed to recreate the surrounding soil environment without disrupting natural water flow. Components can be assembled in-house, enabling rapid design changes without relying on external manufacturing. The sensors transmit data wirelessly over LoRa networks while storing information locally as a backup, and initial testing showed continuous underwater operation for seven to eight months.
For researchers and environmental agencies, the lower-cost design could support more distributed monitoring of groundwater movement, contamination and wetland hydrology. The team is pursuing patent protection to preserve the technology’s intended open-source availability.
