摘要

本研究主要為利用厚膜陶瓷電路基板印刷電路，且經由燒結850℃，再透過蒸鍍製程將TiO2固態轉氣態元子和分子，使其披覆於厚膜陶瓷電路基板上，製作成『陣列型酸鹼感測器元件』，由於厚膜高溫燒結製程所製作出來的線路具有高可靠度及高穩定性之特性優勢，且陶瓷基板具有高抗酸鹼及抗腐蝕之特性，不會因為待測物之極酸鹼性造成影響。透過此陣列型酸鹼感測器元件，即使在惡劣的環境中，仍然不會被干擾且可測得更具信賴之結果。
將酸鹼感測器元件透過標準緩衝溶液（Buffer Solution）PH 6.0、 PH 7.0、PH 8.0以及PH 9.0 於50℃以下進行測試，電荷可有效累積於感測器上，再利用外加Ag/Ag/Cl玻璃參考電極以併排方式，量測酸鹼感測器對於各個標準緩衝溶液（Buffer Solution）之反應結果，靈敏度可達100 mV以上，其線性度更可達0.99以上。
厚膜陣列型酸鹼感測器，不僅具有高感測度和高穩定性外，因為感測器本體是陶瓷基板加厚膜塗料燒結而成，常常被使用於需要高可靠度的環境，由於人每天都需要用水，因此監控水質變成了一個重要的議題。另外，不論是材料本體之耐用性亦或是研究結果所證實之穩定可靠度，皆說明此酸鹼感測器非常適合用於水質監控，而現今空氣汙染情況嚴重，民生飲用水為最需要被監控之水源，因此，此酸鹼感測器用來監控民生用水再適合不過了。除此之外，現在人們喜歡藉由泡溫泉舒壓，此感測器亦可用於溫泉水質之檢測。

This research is to build the array type PH biosensor, and it is fabricated by thick film circuit ceramic substrate. The TiO2 is coated on the circuit by evaporation process. Because the thick film circuit ceramic substrate is fabricated under high temperature（850℃）, it has the following properties: 1. High reliability. 2. Excellent temperature stability. 3. Excellent anti-acid. 4. Excellent anti-corrosion. Because of these characteristics, so that sensor can get the correct data in harsh environments.
The sensitivity of the PH biosensor can be above 100 mV and the linearity more than 0.99 that were measured by contacting PH6.0、PH7.0、PH8.0 and PH9.0 buffers solution under 50℃ with Ag/AG/Cl reference electrode.
People need water every day, but now the water was subjected to all kinds of pollution: pig farming waste water, gravel, garbage and industrial waste water pollution. Therefore, water quality monitoring become an important issue. This research of PH biosensor has excellent reliability, stability and sensitivity. Therefore, this PH biosensor is ideally suited for monitoring the livelihood water. Besides, we also can use the PH biosensor to monitoring hot spring water.
