TI EPC Gen 2晶片幫助Sontec發展效能更強大的金屬黏貼式RFID標籤
: e) p: R* u( I& `
(台北訊，2006年10月16日)　德州儀器 (TI) 今天宣佈，韓國無線射頻辨識 (RFID) 元件與中介軟體的領先開發商暨製造商Sontec已在TI EPC Gen 2晶片的協助下，發展出多款金屬黏貼式 (mount-on-metal) 電子標籤及其RFID應答器，徹底解決採用RFID技術的極高頻 (UHF)應用無法在金屬產品或環境內運作的問題。

新型RFID應答器具備優異的讀取範圍效能，可讓家電、電子裝置和金屬製品等消費產品供應商提供絕佳的供應鏈管理能力。Sontec最初將以亞洲地區的白牌家電和電子產品製造商為銷售對象，但這些產品最終仍會進入日本和美國等全球零售市場。根據協議，TI將供應1,000萬顆Gen 2晶片給Sontec。TI已開始出貨給Sontec，並會在2007上半年持續供應晶片。

金屬會反射RFID標籤發射的極高頻無線電波，而金屬產生的渦流則會減弱訊號。此效應會縮短讀取範圍，使電子標籤在需要10至30英呎讀取距離的零售供應鏈應用中無法發揮最佳效能。

' m- b$ v9 C, Y6 S! }Sontec利用TI Gen 2技術發展電子標籤，為業界首見符合UHF Gen 2規格的零售供應鏈管理用解決方案，能實際應用在充滿金屬製品的嚴苛工作環境。零售商不再需要掌上型或人工解決方案來管理供應鏈的白色家電或電子產品，此電子標籤能在銷售含有大量金屬材料的產品時，準確追蹤零售供應狀態。

TI表示，金屬會導致UHF訊號大幅衰減，因此黏貼在金屬表面的普通UHF應答器會大幅縮短讀取範圍。Sontec的金屬黏貼式封裝技術則能讓UHF Gen 2標籤提供極遠的讀取距離，就算黏貼至金屬表面也可發揮優異效能。這是提供多種解決方案以滿足供應鏈需求的重要關鍵。

有很多方式來解決金屬的問題,單只平面的話可以利用電高天線與金屬的距離並且利用pitch ant的原理來設計指向性天線標籤,不然只能利用吸波或是集波的材料來間隔天線與金屬之間.不過使用再UHF的材料很貴,根本不符合RFID的成本.

我想價格應該不便宜吧...不過能突破這個的確有過人的優勢...

就我所知目前台灣已有廠商自行研發出類似產品了(非代理)，HF與UHF都可以用在金屬上，但液體就不曉得，重點是不便宜ㄚ

水產生的影響也是一個重點吧

如果真的可以突破這一個關卡，那RFID的應用會更加的普及 ，
因為目前的技術瓶頸主要的一項就是金屬產品會影響訊號的傳遞與取得。
