無線電能傳輸技術(shù)（Wireless Power Transfer,WPT）作為一種便捷、安全、高效的能量傳輸方式得到了企業(yè)和研究人員的廣泛關(guān)注。現(xiàn)有無線電能傳輸系統(tǒng)采用的都是平面（2D）線圈,2D線圈可以直接集成在我們的手機、電腦、鼠標等有大平面的電子設(shè)備外殼上,但不能用于電動剃須刀、谷歌眼鏡、植入式醫(yī)療設(shè)備等3D外形的電子產(chǎn)品。近期,電子3D打印技術(shù)的快速發(fā)展為無線電能傳輸系統(tǒng)的設(shè)計、制造提供了新的思路和方法。電子3D打印技術(shù)增加了無線電能傳輸系統(tǒng)中線圈設(shè)計及制造的維度,線圈的設(shè)計、制造不再局限于平面。針對目前無線電能傳輸中遇到的問題,并結(jié)合電子3D打印技術(shù),作者在本文中:提出了一種自由曲面上3D線圈的標準化設(shè)計方法;構(gòu)建了完整的用于計算3D線圈參數(shù)的數(shù)學模型;設(shè)計了一種提高斜面上導電軌跡打印質(zhì)量的加工方法;最后,提出一種基于遺傳算法的3D線圈的優(yōu)化方法。本文的主要研究內(nèi)容如下:（1）驗證了3D打印線圈用于無線電能傳輸?shù)目尚行?并針對不規(guī)則自由曲面上3D線圈無法標準化設(shè)計的問題,提出了一種基于非均勻有理B樣條曲線（Non-Uniform Rational B-Spline,NURBS...
