嗅覺虛擬實境近年來備受矚目，尤其在醫療訓練，消防演練和休閒娛樂方面。嗅覺虛擬實境主要依賴氣味產生器釋放氣味，而利用微機電技術所製造的氣味產生器，體積小且具可攜帶性，適合應用於虛擬實境。
本文針對微機電技術所製作的微氣味產生器：包含蒸發晶片與噴射晶片，設計控制器藉以達到系統的需求，在蒸發晶片部分，在同一個白金薄膜上，同時完成加熱與感測的動作，化簡了製程與晶片設計上的麻煩，並利用脈波訊號來加熱，以CPLD作為控制器，並設計訊號處理電路，完成溫度迴授控制。另外，本文亦針對蒸發晶片的熱擾動現象及實際蒸發情形等，作特性量測。在噴射晶片部分，亦利用CPLD來驅動，完成多點噴射且各點頻率可調變，並設計噴射平台以觀察衛星液珠等的噴射情況，藉此平台來設定操作參數。本文最後整合蒸發晶片與噴射晶片，加入溫度迴授控制來蒸發液珠，觀察液珠蒸發情況，液珠最高可達數百赫茲的噴射頻率，氣味濃度已滿足嗅覺虛擬實境的需求，順利完成微氣味蒸發的控制。
