面對全球的自然資源消耗，以及全球減少碳排放量的環境保護趨勢。再生能源是目前各界努力開發的一種能源形式，其中海浪能源因為有著高能量密度以及我國自然地理的環境優勢，故海浪能源非常值得在我國發展。本實驗室先前也針對水波獵能器之數學、數值以及實驗模型做過相關研究，在本研究中將會建立水波獵能器於拖曳水槽中做實驗測試。在去拖曳水槽實驗之前為了測試新型的儲能整流電路，將建置一小型版本的水波獵能器於實驗室內，其中包含驅動系統與獵能系統，利用驅動系統模擬真實海浪拍打情形，並實際測試獵能系統各元件之物性，收斂實測系統設計之參考。
在拖曳水槽版本的水波獵能系統將使用震盪浮標型(oscillating body)系統的運作模式，其中包含了三大系統，分別為浮標獵能系統、發電機端系統以及儲能系統，透過台灣中部沿海之海象與拖曳水槽中做相似性分析可以得知拖曳水槽中波浪週期為1.2 s, 1.4 s, 1.6 s與波高5 cm, 10 cm，以及系統轉動慣量分別為 、 的發電機系統作為實驗變數，利用人造波浪使浮標上下運動帶動齒條運動使發電機端系統上的齒輪產生運轉，將其電能輸入至新型的可調式電容容值的儲能電路當中。實驗結果指出若使用發電機端系統轉動慣量為 相對於 時，可以提升約2.5倍的能量轉換效率，在實驗變數當中在波浪週期為1.4 s波高為10 cm且轉動慣量為 時，最大能量轉換效率可以達到14.2%。雖然本實驗系統與相關文獻的效率有所差距，但對於整體研究而言，此初步之研究以證明此水波獵能系統有一定的可行性，並對未來高效率的水波獵能器提出實質的改善方法與建議。

To fulfill the global environmental protection requirements of carbon emission reduction, the use of renewable energy has to be increased. And water wave energy certainly is one important form of renewable energy worth further development. In this work, a water wave energy harvester is designed and constructed for experimental testing in the towing tank at NCKU. But to test and optimize the performance of our energy storage electronics before carrying out the tests in the towing tank, a small apparatus is built in our laboratory, which includes a driving system and an energy harvesting system that mimics the wave energy harvester. Moreover, the performance of various components of the energy harvester system also is calibrated and tested in the laboratory, so as to optimize the system design to be physically tested in the towing tank. Specifically, the towing tank version of the wave energy harvester system includes three major systems, namely a mechanical mechanism driven by an oscillating buoy transmitting the wave motion, a generator system converting the mechanical energy of the mechanism to electric energy, and an energy storage system. Through dynamical similarity analysis, nearshore wave data collected on the west coast of central Taiwan are used to determine the experimental parameters, such that the tested system can be thought of as a 1/4 model of a prototype that hopefully can be deployed in the ocean (in the future). It is found in the towing tank tests that, with a wave period of 1.4 s and a wave height of 10 cm, when the moment of inertia is 6.14×10−3 kg ⋅m2 , the maximum energy conversion efficiency of 14.2% can be achieved. This preliminary study shows that the wave energy harvester design has a certain feasibility and worth further development.
