生理感測器節點的製作花費約 8 個月的時間，與感測器網路協定之實作同步進行，感測網路的實 作花了約 3 個月多一點的時間，部署、測試與除錯是最費時的部分，大約耗費剩下的所有時間（6 個月）。我們在製造、硬體的選擇、節點放置、資料傳輸、及可用性方面，學到許多寶貴的經驗。
製造費用 穿戴式生理感測器製作需約新台幣 5 萬元，建構此一超過 30 個節點的感測器網路花 費約台幣 20 萬元，每一節點之元件成本約為台幣 3000 元，其他為配線與 gateway 的花費。這比 全球所有製造者的目錄表價都來得低。若有需要，這些生理感測器與無線感測網路節點可大量生 產並自動組裝，價格預估可壓到更低。我們也因此認為，成本應該不會是未來將感測器網路產品 商業化的瓶頸。
硬體平台之選擇 建築物中感測器節點之部署與建築物之結構與建築材質有密切關連。在工廠式 建築中，因空間較為開放且連續，部署較為容易。而在辦公室或公寓式建築中，地板、天花板、
牆壁則以相對高許多之密度構建。博理館是一棟混和式建築，在四樓（含）以上有開放式空間，
因此一個小型的約 20 個節點的感測器網路可以涵蓋整個四樓至 7 樓的樓板面積。在三樓（含）
以下，是比較辦公室類型的建築方式，樓板是由結實的混凝土隔開，因此會阻隔由感測器節點所 發出之低功率無線電訊號。這意味著，在現代辦公室建築中部署感測器網路，必須採用更為強有 力之閘道節點，如具備更高無線傳輸功率或甚至有線傳輸能力之節點。
節點之擺放位置 在部署感測器網路的過程中，我們曾數次改變中繼節點之配置位置。感測器節 點最終被隱藏起來，或被放置在很高不易被看到或被移動的牆面上。主要是因為人類的好奇心有 時會勝過榮譽感。有二次，我們發現感測器節點被拿走，第一次被拿走的感測器節點，經在被拿 走處貼出告示後， 順利找回來，而第二次則沒如此幸運。我們因此決定放置感測器節點的原則，
不再是最高的覆蓋率，而是最高的安全性。
資料傳送率 感測器資料之傳送率約為 90%-95%，會因天候、建築物中可能產生衝突之無線電 裝置之使用、及電池壽命而有所不同。在這三個因素中，瓶頸中繼節點的電池壽命，對資料傳送 成功率的影響最大。對日常應用而言，為中繼節點佈一次線的成本，可能比經常更換電池的循環 成本來得低。為求較佳之資料完整性與一致性，商業性的感測器網路中的基礎建設節點，較實際 的連接方式應是由牆上之插座供應電源。換言之，對於有線基礎建設之感測器節點而言，能源效 率不再是最重要的議題。然而，對移動式感測器節點而言，能源效率仍是一重要議題。
可用性 由智慧型辦公室的經驗，我們發現目前的生理參數節點尺寸太大，且配戴起來不是很舒 服。電池快沒電時沒有警示，也是待解決的問題之一。大部分的志願參與者建議，最好是能有一
較薄、如悠遊卡大小，且具備充電能力與低電量警示功能的節點。大部分的志願參與者，在模擬
