dc.description.abstract | 環境濕度感測是在不同應用層面都可見的重要功能。其使用方式可以用在偵測及監控環境的狀態以達到穩定的濕度。這種監控系統可以驅使一些農作物或是微生物的生長更加易於掌握。簡而言之,對於多數生命體的存活品質皆會受到濕度所影響。濕度感測器的精準度、穩定度及低消耗皆為製程當中所需考量的重要因素。本研究當中提出一種將訊號放大電路結合濕度感測器。濕度感測器是運用聚3,4二氧乙基噻吩:聚苯乙烯磺酸複合物(PEDOT:PSS)為吸收水分子的聚合物及N+多晶矽奈米線為導電通道之濕度感測系統。這種架構的感測原件比起使用導電聚合物當作導電通道之傳統感測器可測量出更加穩定的反應。本研究所使用的聚合物是噴墨在奈米線段上。此濕度感測架構經由長時間量測已呈現較穩定的反應量。量測結果也顯示良好的單一性,僅對水分有反應。對於常見氣體如氮氣、二氧化碳或是有害氣體如一氧化碳和二氧化氮皆無明顯反應。 | zh_TW |
dc.description.abstract | Humidity sensing has been a key functionality that is used in many different applications. It can be used to monitor the environment to facilitate and maintain the growth of several cultivations or micro-scale colonies of living organisms. The fundamental requirements of humidity sensors should be high stability and accuracy. Additionally, they should also be powered by minimal energy sources for applications that require such precision. In this work we introduce a humidity sensing system that combines a signal amplifying circuit with a humidity sensor. The sensor is built with poly(3,4-ethylenedioxythiophene) polystyrene sulfonate(PEDOT:PSS) as the polymer that traps the water molecules, and N+ polysilicon nanowires as the conducting material. The polymer is inkjet-printed on the nanowire segment of the sensor. This setup is tested and proven to produce relatively stable responses after long periods of testing. The results also shows good selectivity among common gases such as N2, CO2, and other hazardous gases such as CO and NO2. | en |
