    Abstract: 為了讓微飛行器有足夠的升力及推力,輕量化是微飛行器研究的首要課題。本研究成功選擇不同的材料如塑膠、鋁等高強度的材料進行馬達基座等零組件的減重,並搭配上由國外購得之質輕齒輪及管徑更小的中空管,使齒輪傳動系統的部份達到輕量化,並讓微飛行器成功飛行15 秒以上。此外,為了能更精確的調校微飛行器之空氣動力特性,本文也提出以一嶄新的智慧型機翼,探討拍撲式微飛行器之空氣動力特性。此研究特別指定拍撲翼之右翼翼膜為聚對二甲苯(parylene),左翼翼膜為聚對二甲苯與PVDF(polyvinylidene fluoride)之複合機翼。在風洞測試時,左翼之PVDF 感應器可直接獲得左翼之升力訊號,整個微飛行器之升力訊號則由多軸力規擷取,此種機翼設計構型可輕易找出左翼及右翼個別之升力貢獻。本研究即利用此方法並微調兩翼間拍撲運動的相位差,來調校拍撲式微飛行器之空氣動力特性。
    In order to make the Micro Aerial Vehicle (MAV) having sufficient lift and thrust, reduce the weight of the MAV is the main subject of this article. Here we show the different choice in materials, such as plastic and aluminum, and we had successfully miniaturized the framework of the motor assembly. We combine light gears bought from abroad, the hollow tubes with small radius, and the motor base with each other, so reduce the weight of the transmission system dramatically. As a result our MAV can successfully fly for 15 seconds at least. Additionally, for the purpose of adjusting the aerodynamics of the MAV more precisely, we also presented an idea of fabricating smart wings for studying the aerodynamics of the flapping MAV. In this portion, we assigned a parylene film as the right wing, and a composite PVDF-parylene film as the left wing. In the wind tunnel test, the PVDF sensor of the left wing can output the lift signal directly, and the entire lift signal of the MAV can be obtained by a load cell. This design of wings can easily find the contribution of lift from the left wing and the right wing individually. In this research, we use this approach to do the fine-tuning of the phase lag resulting from flapping motion between two wings, and adjust the aerodynamics of the flapping MAV.
