本研究旨在開發一種全固態安培式氧化硫感測器，該感測器通過具有極高離子導電性的NASICON 型損耗LATP 提供良好的傳感。另外，NASICON 固態感測器的工作溫度可以低於400 o CC，從而降低了操作成本。然而溫度有利於工作和維護，成本適用於各種環境和安裝條件。推進部分採用納米材料來擴展界面，以組件感測器的響應時間，對每個功能層進行精心設計和規劃，從而製造出一種安培感測器。氣體物體進行SO 2 感測器性能測試。
為模擬工廠煙囪的高溫環境，感測器將被設置為控制中心，將溫度濕度實際溫度，並通過不同濃度的SO 22（0ppm 〜800ppm800ppm）模擬氣體進行感測性能測試，以了解設計的氣體感測器信號是否與SO 2 濃度相關。在普通安培式感測器的工作條件下，感測器在單向操作下進行一定的時間測試，硫酸鋰工藝在電鍍界面測量，導致電鍍液密度增加，從而降低。因此，在本研究中，採用工藝設計重新設計了硫酸鋰工藝，以提高工藝水平。信號中斷現象。當工作溫度為150150℃，輔助電壓為2.5V2.5V，循環速率為50mv/s 時，感測器在SO 2 濃度為0ppm 至800ppm 時具有線性關係。經過300 次循環測試後，信號值與初始信號值僅下降88％，表明感測器具有長期穩定性。

This research aims to develop an all-solid-state amperometric sulfur
dioxide sensor, which provides good sensing sensitivity through the
NASICON type electrolyte LATP with extremely high ionic conductivity. On
the other hand, the operating temperature of the NASICON solid state
electrolyte sensor can be below 400°C which reduce the operating cost.
However, the low working temperature is beneficial to the operation and
maintenance cost of the components, applicable environment and installatio n
conditions. The electrode part uses nanometer materials to extend the three
phase boundary, so as to reduce the response time of the sensor and carry out
the modular design and planning of each functional layer in order to make an
Amperometric sensor. An d using simulate the gas composition for SO2 sensor
performance test.
In order to simulate the high temperature environment of the factory chimney,
the sensor will be placed in a quartz tube to raise the temperature to the actual
temperature, and simulated gas with different concentrations of SO 2
(0ppm~800ppm) will be passed through for sensing performance test to know
whether the signal of designed gas sensor is correlated with the concentration
of SO 2 . Under the operating condition of an ordinary amperome tric sensors,
the sensor is tested under a unidirectional electric field for a certain period of
time, lithium sulfate products tend to accumulate in the three phase boundary,
resulting in an increase in the resistance of the three phase interface and a
decrease in sensitivity. Therefore, in this study, the cyclic electric field design crease in sensitivity. Therefore, in this study, the cyclic electric field design was used to decompose the accumulated lithium sulfate product in real time to was used to decompose the accumulated lithium sulfate product in real time to reduce the phenomenon of signal degradation. And when the working reduce the phenomenon of signal degradation. And when the working temperature is 150temperature is 150ooC, the auxiC, the auxiliary voltage is 2.5V, and the cycle rate is liary voltage is 2.5V, and the cycle rate is 50mv/s, the sensor has obvious linear relation when SO50mv/s, the sensor has obvious linear relation when SO22 concentration is concentration is 0ppm to 800ppm. After cyclic testing for 300 cycles, the signal value and the 0ppm to 800ppm. After cyclic testing for 300 cycles, the signal value and the initial signal value only degrade by 8%, which shows that thinitial signal value only degrade by 8%, which shows that the sensor has longe sensor has long--term stability.term stability.
