本文設計使用呼拉圈運動型式的獵能器，放在船舶上擷取波浪造成船體運動的能量，再將此動能轉為電能。磁路使用Halbach array的磁鐵排列方式，增強線圈放置側的磁力，並進一步模擬不同磁鐵尺寸對發電量差異。Halbach array磁鐵排列方式經過適當的尺寸設計後，可提升約14.3%發電量。
首先分析船舶在海上航行時的運動狀況，其中橫搖運動阻尼較低，可以產生較大的動能，其橫搖頻率能量主要分布在0.15到0.3 Hz之間。接著設計獵能器為偏心系統，並推導數學模型，調整適當配重塊位置可使獵能器產生呼拉圈運動，提高發電量。模擬在不同船舶不同海況下獵能器產生呼拉圈運動的狀況，並且比較不同配重塊位置獵能器發電量的差異，模擬適當配重塊位置輸出功率約為2 mW可提升約10倍發電效率。再來用近似解對比數值解結果，驗證方程式正確性。最後實驗與模擬發電量誤差不超過10%。實驗結果在橫搖頻率0.3 Hz橫搖角度15度下可以產生約1.1 V電量。當負載電阻為430歐姆時，有最大功率輸出約2.05 mW。

This research developed an eccentric disk and novel circular Halbach array to harvest wave energy from the rolling motion of a ship. The designed eccentric disk revolves in a motion that mimics a hula-hoop at higher angular speeds than eccentric disks oscillate normally having. The power output of the eccentric disk was approximately 2.05 mW. The proposed energy harvester can serve as a back-up power source during emergencies.
