技術說明

藉由新型開發之極化方式，分別對單一層或複合層之聚偏氟乙烯壓電膜實施極化，可提供三維空間XYZ之量測。本發明專利包括四種型式之聚偏氟乙烯壓電膜層數及極化模式。 型式一: 單一層聚偏氟乙烯壓電膜 極化於單一層，同時具有d33及d15功能，提供三維空間XYZ之量測。 型式二: 雙層聚偏氟乙烯壓電膜 其中一層極化產生d33功能，提供Z之量測。另一層極化產生d15功能，XY之量測。 型式三: 三層聚偏氟乙烯壓電膜 其中一層極化產生d33功能，提供Z之量測，另二層極化產生d15功能，分別提供XY之量測。 型式四: 三層聚偏氟乙烯壓電膜 每一層極化產生d33功能，提供Z之量測，分別提供三維空間XYZ之量測。 A 3-axis force sensor consists of single or multiple layers of PVDF are designed with four types. TYPE 1) consists of one layer of PVDF is designed. The PVDF layer is designed of combination of both d33 and d31 modes, able to measure response along the X-, Y-, Z-axis respectively. The thinner sensor would give larger response and higher sensitivity. TYPE 2) consists of two layers of PVDF is designed. The first PVDF layer is designed of d33 mode able to measure response along the Z-axis and the second PVDF layer is designed of d31 able to measure response along the X- and Y-axis. TYPE 3): consists of three layers of PVDF that is constructed with d33 mode and d31 mode. Each layer is in charge of the measurement along one-axis direction. TYPE 4) 3-axis sensor with 3 layers of PVDF: Using d33 mode for all layer #1, layer #2 and layer #3 is designed. Each layer is in charge of the measurement along one-axis direction.
