本文設計一新型織狀壓電薄膜獵能器用以獵取微小波浪能，此獵能器被設計於使用於小振幅之波浪，且此獵能器可藉由懸掛彈簧之不倒翁型敲擊結構將低頻的波浪力轉換為較高頻的振動力。此織狀壓電薄膜獵能器包含三元件：織狀PVDF薄膜、懸掛彈簧之不倒翁型敲擊結構及拍打裝置。敲擊結構包含三種設計：圓柱型、半膠囊型與不倒翁型，根據模擬結果顯示，不倒翁型之敲擊結構比圓柱形和半膠囊型能施加更大的應力於壓電薄膜上，進而產生更多電能，另一方面，壓電薄膜之支撐材料長度並不會顯著影響此獵能器的獵能效率。此新型織狀壓電薄膜獵能器在1.5cm、1.75cm、 2cm振幅下可分別產生0.31mW、0.48mW、0.67mW的能量。織狀PVDF結構產生之電能約為多層PVDF結構之2.6-2.8倍。當PZT薄膜亦使用織狀結構編織時，預估亦可比一般PZT薄膜結構得到2.6-2.8倍之電能。

The thesis presents a novel knitted PVDF films energy harvester with knocking structure for tiny ocean waves. This design is used in low amplitude wave condition and it can transform the low frequency of waves into higher frequency vibrations using a knocking structure with a spring. This knitted PVDF films energy harvester contains three units which are knitted PVDF films, beating element and a knocking structure with a spring. Knocking structure is designed in three kinds of shapes which are cylinder shape, half-capsule shape and tumbler shape. For the simulation results, the length of supporting layers does not affect the harvesting efficiency for this structure obviously. In addition, knocking structure in tumbler shape can add more stress in piezoelectric materials than with cylinder shape or half-capsule shape. The novel knitted PVDF films energy harvester with knocking structure can generate 0.31mW, 0.48mW, 0.67mW in 1.5cm, 1.75cm, 2cm amplitude of waves respectively. The knitted PVDF films energy harvester is 2.6-2.8 times greater than the multi-PVDF films type in generating energy. When weaving PZT films to a knit, this energy harvester can transform more wave energy into usable electric energy.
