Description

一种面膜及其制备方法 技术领域
本发明属于美容仪器与设备技术领域，特别涉及一种带有可拉伸柔性电路的面膜及其制备方法。
背景技术
自古至今，人类一直不断地寻找延缓面部衰老的方式。人们最常用的美容产品，就是面膜。面膜，作为美容保养品的一种载体，是女性护肤最重要的面部护理产品之一。
面膜种类繁多，传统的药物护理面膜主要包括营养粉末调和的涂抹面膜、吸附有营养成分的片式膜状面膜。
另外还有LED光子嫩肤面膜，利用光动力达到美容效果。LED作为一种新型光源，随着制备工艺的进步，其发光波长分布更窄且功率更高，因此可以充分发挥其生物学效应，例如红光和红外有利于缓解疼痛和促进伤口的愈合、黄光治疗湿疹等已经广泛应用于临床治疗。
此外还有一些促进营养成分吸收的超声导入仪等相关产品。通常的药物面膜，其中的水分和化学成分直接与人的脸部皮肤接触，营养成分的吸收与皮肤自身状况密切相关，由于皮肤细胞自身的局限，对与脸部皮肤直接接触的水分和化学成分的吸收不够充分，吸收速度也不够快。超声波有机械效应、温热效应和理化效应这三大效应。低功率密度的超声波对人体主要产生机械效应和温热效应，而不是不可逆的理化效应，所以不会造成伤害。机械效应可以使水分子在皮肤表面高速振动，温热效应可以使汗毛孔打开并加速血液循环，其促进皮肤吸收药物和水分的作用已被临床证实。
可见，随着物理技术的发展，人们也越来越多的将物理技术应用在美容护肤领域。
市场上现在已有可以帮助吸收美容药物和水分的超声导入仪，可以显著提高美容药物和水分的吸收率，但是这些超声导入仪质地坚硬，而且必须手持振动源往复移动使用。市场上也有一些大型的超声导入设备，不用手持振动源，但体积庞大且质量笨重，不便于随身携带和随时随地使用。
以光子嫩肤技术为基础的LED面膜，通过嵌入的LED电路板，提供各种色光，从而促进皮肤的各种生物化学过程。目前的LED面膜存在很多不足之处，例如LED面膜本体是质地较硬的面罩，虽然可以排布较多LED灯珠，达到面部光照均匀的效果，但它不能直接贴合人脸，且灯珠与面罩是两组部件，需要进行组合，导致面膜整体重量较大，因此用户使用时会感受到面部有局部压迫感；同时，面膜使用过程无法进行其他活动。另外还有采用质地较软的硅胶作为面膜本体，可以直接与人脸接触，但是由于电路的需要，通常采用条带式灯珠作为光源，局部的镶嵌在硅胶本体中，灯珠用量较少，因而很难均匀照射整个面部；同时，条带式灯珠使得整个面膜实际比较硬，不能卷曲，无法随意折叠，不能便携使用。
还有其他的一些通过物理过程进行美容的产品，其由于电路的存在，而不能随意使用，不管是从使用上还是从携带上，都为使用者造成了诸多不便，无法实现与现有的便携式面膜的结合。

在采用可拉伸LED线路作为柔性可拉伸电路的实施例中，形成的可拉伸LED面膜，能够将灯光美容技术和面膜技术有效结合起来，利用可拉伸的LED线路结构，将LED灯均匀分布于面膜上，结合LED灯体积小、使用方便、发光波长分布窄等特点，不仅使面膜保持可拉伸的性能，可以完美贴合不同的脸型，从而适用于任何人，而不必再根据个人的需求再进行重新定制，也同样可以达到个性化的适应，进一步提高美容效果；同时，可拉伸LED面膜可以随意卷曲，随身携带，提高用户体验，从而解决了当前面部光疗设备质地较硬、不方便携带等问题，可以制备成小巧、便捷携带的随身面膜，成本低廉，易于实现产业化生产。
这种可拉伸LED面膜也能够克服现有LED面膜电路串并交替、导线环绕密布的问题。各LED灯相互之间采用为全并联连接，如某一LED断路，不会影响其他LED灯正常工作。另外，LED灯处于网格交叉节点，即使节点周围一根或几根网格线断裂，但只要有一根网格线完好，则可以保证LED灯正常工作。此外，本发明产品外观外形即为导线线路外形，通过对LED排布和走线的精心设计，使得产品外形整齐美观和布线简洁；采用外形重合的多层FPC板电路设计，使得一层电路板仅为一种颜色灯或是公共极的控制层，通过此设计可以简单的实现各层板对应各颜色灯的独立通断控制。

具体实施方式
通过参考示范性实施例，本发明技术问题、技术方案和优点将得以阐明。然而，本发明并不受限于以下所公开的示范性实施例；可以通过不同形式来对其加以实现。说明书的实质仅仅是帮助相关领域技术人员综合理解本发明的具体细节。
下面结合具体的实施例及附图对本发明做进一步阐述。
如图1至图5(a)-图5(d)所描绘的，在一实施例中，提供了一种面膜，所述面膜包括：带有可拉伸柔性 电路板的面膜本体1100，连接器1200，控制单元1300；其中，
所述带有可拉伸柔性电路板的面膜本体1100，用于提供物理美容功能，同时用于实现与皮肤的友好接触；
所述连接器1200，用于为所述可拉伸柔性电路板提供电源与控制信号的接口；
所述控制单元1300与连接器1200非固定连接，用于为所述可拉伸柔性电路板提供控制信号。
在使用时，控制单元和供电单元可以通过线缆与连接器连接，也可以通过相应的插头和插座结构连接。
进一步的，所述带有可拉伸柔性电路板的面膜本体中的柔性电路板，为具有物理美容功能的电路板。
进一步的，所述带有可拉伸柔性电路板的面膜本体1100包括：外层面膜状弹性薄膜、内层面膜状弹性薄膜、可拉伸柔性电路板；所述可拉伸柔性电路板位于外层面膜状弹性薄膜和内层面膜状弹性薄膜之间。
进一步的，所述可拉伸柔性电路板，包括：连接层电路、绝缘层、阴极层电路。
图2为本实施例的可拉伸柔性电路板中阴极层电路板的单个岛桥结构的示意图。如图2所示，所述阴极层电路为岛桥结构的电路，岛用于作为互相导通的电极，桥用于以可拉伸的方式连接岛；
图3为本实施例的可拉伸柔性电路板中连接层电路板的焊盘布置示意图。如图3所示，所述连接层电路为岛桥结构的电路，岛用于作为互相导通的电极，岛上有用于连接物理美容终端的若干焊盘及相应的美容终端，所述焊盘通过打孔的方式与阴极层电路的相应岛上的电极相互连通，桥用于以可拉伸的方式连接岛。
所述绝缘层用于隔开所述连接层电路和阴极层电路。
还有另一种实现方案，阐述如下：
阴极层电路为节点网状结构的电路，节点用于作为互相导通的电极，网用于以可拉伸的方式连接节点；连接层电路为节点网状结构的电路，节点用于作为互相导通的电极，节点上有用于连接物理美容终端的若干焊盘及相应的美容终端，所述焊盘通过打孔的方式与阴极层电路的相应节点上的电极相互连通，网用于以可拉伸的方式连接节点。绝缘层用于隔开所述连接层电路和阴极层电路。
图4为本实施例的可拉伸柔性电路板中若干个岛桥结构的示意图。如图4所示，若干个岛桥结构相互连接导通，构成可拉伸的电路结构。优选的，这里的岛桥结构是基于柔性电路板进行设计的。图5(a)-图5(d)为本实施例的岛桥结构中四种不同的桥构形示意图。如图5(a)-图5(d)所示，岛桥结构中的桥，可以通过多种不同的形式得以实现。如此，可拉伸电路板可以进行任意折叠或卷曲，而不会破坏电路结构或功能性。
在一些优选的实现方式中，可拉伸柔性电路板不仅包括岛桥结构，还包括用于引电流的可拉伸导线。若所需工作电流较大，可加宽引流导线且使其分布于整个面膜的外圈。
由于本实施例的面膜带有可拉伸柔性电路板，因此可在柔性电路板的基础上与其他具有物理美容功能的元件进行结合。例如，可以与LED贴片进行结合，制备LED面膜；与超声贴片结合，制备超声面膜；还可将所述柔性电路板本身制备成具有温热功能的电阻电路，从而发挥温热功能。当然，上述举例对本发明并不构成限制，本发明可与任意在电路下发挥物理美容功能的元件进行配合，从而制备成相应的面膜。
在医疗美容方面，红光促进纤维母细胞和胶原蛋白的产生，起到淡化细纹、亮白皮肤、增加皮肤的保湿性和弹性、恢复皮肤活力等作用。蓝光具有治疗皮肤痤疮、消炎祛痘、平衡油脂分泌的作用。绿光具有减少油脂分泌、平衡水油比例、消除水肿的作用。黄光可以加强血液和淋巴循环、提升细胞氧的交换、加速角质层脱落，起到改善肤色、有效吸收护肤品的营养物质和减少细纹等作用。不同颜色的光具有不同的美容功效，已经被广大研究者所认同。而上述光的产生，可由LED实现。
另外，超声波有机械效应、温热效应和理化效应这三大效应。低功率密度的超声波对人体主要产生机械效应和温热效应，没有不可逆的理化效应，所以不会造成伤害。机械效应可以使水分子在皮肤表面高速振动，温热效应可以使汗毛孔打开并加速血液循环，其促进皮肤吸收药物和水分的作用已被临床证实。通过由压电陶瓷片构成的超声单元，连接入可拉伸柔性电路板中，在控制单元的激励下，发生压电效应产生超声，从而实现美容产品的吸收。
当将所述柔性电路板本身制备成具有温热功能的可拉伸分形结构电阻时，通过分形结构电阻丝和面膜状弹性薄膜的配合，完美贴合任意脸型，可配合其他面膜的使用，实现对药物或水分吸收的促进作用，提 高药物或水分的吸收速度和吸收率，也可单独使用，可以促进组织新陈代谢和自我修复；同时，温热辅助面膜可以弯曲和拉伸，可卷曲收藏，携带方便，操作简单，成本低廉。
本实施例带有可拉伸柔性电路板的面膜，通过优化可拉伸柔性电路板轮廓形状，由若干块联通组成可拉伸柔性电路板，可使其具有超过30％的可拉伸性，从而使面膜保持可拉伸的性能，可以完美贴合不同的脸型，从而适用于任何人。具体而言，在现有柔性电路板加工工艺和功能器件尺寸的限制下，为了使面膜完美贴合人脸，可拉伸柔性电路板中的岛桥结构电路并不适合完全覆盖整个面部。优选的方案是，在面部轮廓曲率变化较小的若干区域放置周期排列的岛桥结构电路，在面部轮廓曲率变化较大的地方，仅仅排列曲线形导线用于联通电路。具体实施方式就是，额头、脸颊、下巴和鼻子，这几处各有周期排列的岛桥结构电路，而它们之间通过曲线形导线联通。
同时，由于电路的存在，可以添加不同种类的物理美容终端，如LED贴片实现色光照射，达到光子嫩肤的目的；再如，添加超声贴片，达到促进面部护肤产品的吸收。也可以根据需要，添加其他物理美容终端，实现个性化的定制。带有可拉伸柔性电路板的面膜可以随意卷曲，随身携带，操作简单，可以美容的同时兼顾其他事情，方便，省时。

步骤S12，制备可拉伸柔性电路板，所述可拉伸柔性电路板本身为具有物理美容功能的电路板，或具有接入相应的物理美容终端的接口；
步骤S13，将接有连接器的带有可拉伸柔性电路板的面膜本体封装在外层面膜状弹性薄膜和内层面膜状弹性薄膜之间，通过在两层面膜状弹性薄膜间灌注液态弹性密封胶进行封装。
优选的，所述物理美容终端，包括：LED灯贴片，超声单元贴片中的一种或两种；
其中，所述LED灯贴片用于提供色光，所述超声贴片用于发生压电效应产生预设频率的超声波。

采用绝缘层隔开每层连接层电路和阴极层电路。
阴极层电路制备成岛桥结构图案的电路，岛为互相导通的电极，桥以可拉伸的方式导通各个岛。
连接层电路包括焊盘，用于以焊接的方式连接物理美容终端，这里的物理美容终端均为贴片式结构。其中，焊盘以打孔的方式与阴极层电路相连。
焊接完成后，可以使用激光切割的方法去镂空柔性电路板。沿着岛桥结构图案的轮廓切割，从而最终获得电路板的可拉伸性。现有技术中通常使用等离子刻蚀完成岛桥结构，而采用激光切割适用于板材厚度较大的工况，加工效率更高，成本更低。
所制备的带有可拉伸柔性电路板的面膜进行使用时，准备工作完成后，将所述带有可拉伸柔性电路板的面膜以适合使用者脸型的方式贴合于面部，开启控制单元的电源，并设定相应的控制信号。
由以上技术方案可以看出，本发明实施例的一种带有可拉伸柔性电路板的面膜及其制备方法，通过连接器将带有可拉伸柔性电路板的面膜本体和控制单元相连，带有可拉伸柔性电路板的面膜本体提供物理美 容过程的电路板，接入相应的物理美容终端，同时用于实现与皮肤的友好接触；控制单元与连接器非固定连接，用于为所述可拉伸柔性电路板提供电源与控制信号。本发明带有可拉伸柔性电路板的面膜，使面膜保持可拉伸的性能，可以完美贴合不同的脸型，从而适用于任何人；同时，由于电路的存在，可以添加不同的物理美容终端，如添加LED贴片实现色光照射，达到光子嫩肤的目的；再如，添加超声贴片，达到促进面部护肤产品的吸收。也可以根据需要，添加其他物理美容终端，实现个性化的定制。带有可拉伸柔性电路板的面膜可以随意卷曲，随身携带，操作简单，可以在美容的同时兼顾其他事情，方便，省时。

面膜状弹性内层2100为一种可拉伸的匀光硅胶薄膜、匀光乳胶薄膜或匀光橡胶薄膜，对人的皮肤无刺激、无伤害；由于内层直接接触人的脸部皮肤，需要LED的光透过，所以必须选用透光性好的匀光材料。

如图6所示，对所述可拉伸LED线路2200进行了放大。其中，2201为所述可拉伸LED线路2200的第一种实现方式，即岛桥结构。其中，两个方形的单元为岛，连接两个岛的部分为桥；2202为所述可拉伸LED线路2200的第二种实现方式，即分形结构，与第一种方式不同的地方即连接两个岛的桥为第一种实现方式中桥的线型的分型结构，具有更好的可拉伸性能。所述LED灯2300均匀的分布于LED线路2200中。LED灯2300所发出的光，透过透光性好的面膜状弹性内层2100，均匀的照射在美容者的脸上，实现均匀的美容效果。这里的LED灯2300，优选为红色灯、蓝色灯、绿色灯、黄色灯中的一种或多种。如本实施例第一段所述，不同颜色的灯具有不同的美容效果，生产商或使用者可根据不同的需求，选择不同的灯光或灯光组合。

所制备的可拉伸LED面膜，其中的面膜状，根据大众脸型设计模板一次成型，如图6所示。当使用的时候，将主要的眼部、唇部孔与相应部位对齐后，整个面膜贴合在脸上，由于面膜的可拉伸性能，可完整的贴合于不同的脸型，其中发挥美容作用的是遍布其中的LED灯发出的不同波长的光线。使用者可以根据自己的需求，通过控制电路控制打开哪种颜色的LED灯，如，当需要具有减少油脂分泌、平衡水油比例、消除水肿时，可开启绿色LED灯开关。当面膜用完后，切断电源，断开控制电路，将面膜主体卷曲或折叠，体积小巧，方便携带。
本实施例所述可拉伸LED面膜制备方法，将灯光美容技术和面膜技术有效结合起来，利用可拉伸的LED线路结构，将LED灯均匀分布于面膜上，结合LED灯体积小、使用方便、发光波长分布窄等特点，不仅使面膜保持可拉伸的性能，可以完美贴合不同的脸型，从而适用于任何人，而不必再根据个人的需求再进行重新定制，也同样可以达到个性化的适应，进一步提高美容效果；同时，可拉伸LED面膜可以随意卷曲，随身携带，提高用户体验，从而解决了当前面部光疗设备质地较硬、无法随身携带等问题，可以制备成小巧、便捷携带的随身面膜，成本低廉，易于实现产业化生产。

本实施例同时提供上述面膜的制备方法，包括如下步骤：
步骤S1，制备外层面膜状弹性薄膜和内层面膜状弹性薄膜；
步骤S2，制备超声阵列可拉伸电路板；

优选的，所述外层面膜状弹性薄膜为硅胶薄膜、乳胶薄膜或橡胶薄膜；所述内层面膜状弹性薄膜为硅胶薄膜、乳胶薄膜或橡胶薄膜。所述步骤S4中，将接有连接器的超声阵列可拉伸电路板封装在外层面膜状弹性薄膜和内层面膜状弹性薄膜之间，通过在两层面膜状弹性薄膜间灌注液态弹性密封胶进行封装，使薄膜间充满液态弹性密封胶，待弹性密封胶固化即完成超声辅助面膜本体的制作，弹性密封胶和两层面膜状弹性薄膜应有很好的柔性和可拉伸性。
进一步的，步骤S2制备超声阵列可拉伸电路板，可以有两种不同的制备方式，下面分别对两种制备方式作详细说明。
方式一，所述制备超声阵列可拉伸电路板包括如下步骤：
步骤S211，切割压电陶瓷片，将所述压电陶瓷片封装到料盘内。
这里的压电陶瓷片可以是锆钛酸铅压电陶瓷(PZT)、铌酸钠钾基陶瓷(KNN)、BNT基压电陶瓷、BaTiO3基压电陶瓷、铋层状结构压电陶瓷以及一些掺杂的二元系和三元系压电陶瓷等。切割方式可以是精密的薄砂轮切割或激光切割。切割前要给极化方向的正面或负面做好标记，比如用铅笔画一个小点。切割后将压电陶瓷片封装到料盘内，分为极化方向正面向上和极化方向负面向上两种摆放方式，以有利于后续的超声单元的制备。
步骤S212，制备超声单元。
这里的超声单元包括两个压电陶瓷片和连接电路板，连接电路板由第二双面柔性覆铜板经过光刻腐蚀和激光切割外形而制成，连接电路板包括连接层、底层及中间的绝缘薄膜。优选的，绝缘薄膜为聚酰亚胺薄膜。
连接层为两个焊盘，每个焊盘通过打孔的方式与底层导通。两个焊盘各焊接一个压电陶瓷片，其中一个与压电陶瓷片的极化方向正面焊接，另一个与另一个压电陶瓷片的极化方向负面焊接，制成一个超声单元。具体焊接时，在焊盘区域上抹上锡膏，用贴片工艺把压电陶瓷片放在锡膏上，经过回流炉即焊接完成。两个焊盘上所贴的压电陶瓷片都是左边的极化方向向上而右边的极化方向向下，也可以统一是右边的极化方向向上而左边的极化方向向下。每个超声单元的焊接方式相同，保证每个超声单元具有相同的压电陶瓷片的极化方向。
步骤S213，制备超声阵列可拉伸电路板。
这里的超声阵列可拉伸电路板以第一双面柔性覆铜板为基础制作而成，第一双面柔性覆铜板包括第一层金属箔、第二层金属箔及中间的绝缘层。优选的，这里的绝缘层采用聚酰亚胺薄膜，金属箔采用铜箔。
将第二层金属箔制备成岛桥结构的电极作为第一双面柔性电路板的第二层电路。
将第一层金属箔制备成每个岛都包括两个焊盘的岛桥结构电路，作为第一双面柔性电路板的第一层电路，将每个岛上的两个焊盘与所述超声单元的压电陶瓷片再进行焊接；其中一个焊盘以打孔的方式与所述第二层电路导通，另一个焊盘通过第一层电路的岛桥结构电路相互连通。这一步骤所用焊锡的熔点比步骤S212中焊接所用焊锡的熔点低，所以过回流炉时温度也可以较低，连接层上的焊锡不会熔化。
焊接完成后，再使用激光切割或等离子刻蚀的方法去镂空第一双面柔性电路板中的绝缘层，沿着岛桥结构图案的轮廓切割或刻蚀相应的面积，来获得第一双面柔性电路板的可拉伸性，此时第一双面柔性电路 板变为可拉伸电路板，从而最终得到超声阵列可拉伸电路板。
上述第一层电路和第二层电路的岛桥结构制备过程，可以通过光刻腐蚀工艺实现，也可以通过激光切割或等离子刻蚀的方式实现。
方式二，所述制备超声阵列可拉伸电路板包括如下步骤：
步骤S221，切割压电陶瓷片，将所述压电陶瓷片封装到料盘内。
这里的压电陶瓷片可以是锆钛酸铅压电陶瓷(PZT)、铌酸钠钾基陶瓷(KNN)、BNT基压电陶瓷、BaTiO3基压电陶瓷、铋层状结构压电陶瓷以及一些掺杂的二元系和三元系压电陶瓷等。切割方式可以是精密的薄砂轮切割或激光切割。切割前要给极化方向的正面或负面做好标记，比如用铅笔画一个小点。切割后将压电陶瓷片封装到料盘内，分为极化方向正面向上和极化方向负面向上两种摆放方式，以有利于后续的超声单元的制备。
这一步骤与方式一的步骤S211相同。
步骤S222，压电陶瓷片与第一双面柔性电路板的焊接。
第一双面柔性覆铜板包括第一层金属箔、第二层金属箔及中间的绝缘层。优选的，这里的绝缘层采用聚酰亚胺薄膜，金属箔采用铜箔。
将第二层金属箔制备成岛桥结构的电极作为第一双面柔性电路板的第二层电路。
将第一层金属箔制备成每个岛都包括两个焊盘的岛桥结构电路，作为第一双面柔性电路板的第一层电路，每个岛上的两个焊盘各焊接一个压电陶瓷片，其中一个焊盘与压电陶瓷片的极化方向正面焊接，另一个焊盘与另一个压电陶瓷片的极化方向负面焊接；其中一个焊盘以打孔的方式与所述第二层电路导通，另一个焊盘直接作为第一层电路的相互连通的岛桥结构电路的一部分。
具体焊接时，在焊盘区域上抹上锡膏，用贴片工艺把压电陶瓷片放在锡膏上，经过回流炉即焊接完成。每个岛的两个焊盘上所贴的压电陶瓷片都是左边的极化方向向上而右边的极化方向向下(也可以统一是右边的极化方向向上而左边的极化方向向下)。每个岛的焊接方式相同，保证后续形成的每个超声单元具有相同的压电陶瓷片的极化方向。
上述第一层电路和第二层电路的岛桥结构制备过程，可以通过光刻腐蚀工艺实现，也可以通过激光切割或等离子刻蚀的方式实现。
步骤S223，导通压电效应电路，形成超声单元。
这里导通，通过连接电路板来实现，连接电路板由第二双面柔性覆铜板经过光刻腐蚀铜箔和激光切割外形而制成，所述连接电路板包括连接层、底层及中间的绝缘薄膜。优选的，绝缘薄膜为聚酰亚胺薄膜。
连接层为两个焊盘，每个焊盘通过打孔的方式与底层导通。两个焊盘与所述步骤S222中每个岛上所焊接的两个压电陶瓷片分别进行焊接，从而使得两个压电陶瓷片形成两个串联的压电效应电路，通电时两个压电陶瓷片产生同步超声。这里每个岛上的两个压电陶瓷片，与相焊接的连接电路板共同构成一个超声单元。这一步骤所用焊锡的熔点比步骤S222中的焊接所用的焊锡熔点低，所以过回流炉时温度也可以较低，第一双面柔性电路板上的焊锡不会熔化。
焊接完成后，采用激光切割或等离子刻蚀的方式镂空第一双面柔性电路板中的绝缘层，沿着岛桥结构图案的轮廓切割或刻蚀相应的面积，来获得第一双面柔性电路板的可拉伸性，此时第一双面柔性电路板变为可拉伸电路板，从而最终得到超声阵列可拉伸电路板。
步骤S5中，由连接器连接到激励单元，激励单元为超声波发生器(超声波激励器)电路板，它使用大容量的移动电源(比如充电宝)供电。超声波发生器输出电压的频率为超声辅助面膜的固有频率，输出电压的幅值可调节。
所制备的可拉伸超声辅助面膜进行使用时，在面部涂抹美容产品，或配合其他类型的药物面膜；准备工作完成后，将所述可拉伸超声辅助面膜以适合使用者脸型的方式贴合于面部，覆盖已涂抹美容药品或覆盖面膜所在的区域；将激励单元通过连接器与超声阵列可拉伸电路板连接好，选择合适的超声波频率，也可以根据需要设定时间，打开电源，开始感受药物和水分的吸收。
由以上技术方案可以看出，本发明实施例的可拉伸超声辅助面膜制备方法，将超声阵列可拉伸电路板封装在外层面膜状弹性薄膜和内层面膜状弹性薄膜之间，用于产生预设频率的超声波；连接器将超声阵列 可拉伸电路板与激励单元相连，通过激励单元为超声阵列可拉伸电路板提供产生预设频率超声波的激励电压，从而实现超声辅助面膜的功能。本发明超声功能通过可拉伸辅助面膜的方式，完美贴合人脸，配合其他面膜的使用，实现对美容过程中药物或水分吸收的促进作用，相比直接使用美容药物面膜，大幅提高药物或水分的吸收速度和吸收率；相比使用超声导入仪，能够保持水分不易蒸发，操作更简单；同时超声辅助面膜可以折叠或卷曲，携带方便。

此外，面膜的可拉伸性与电阻丝的电阻存在矛盾，故要选择合适的线宽，保证超过30％的拉伸性同时导线电阻不至于太大，从而保证亮度均匀，局部不发烫。

由以上技术方案可以看出，本实施例的可拉伸温热辅助面膜制备方法，将可拉伸电路板封装在外层面膜状弹性薄膜和内层面膜状弹性薄膜之间，用于产生温热效应；连接器将可拉伸分形结构电阻丝与电源相连，从而实现温热辅助面膜的功能。本实施例的可拉伸温热物理面膜的制备方法，将分形结构电阻丝与面膜状弹性薄膜相结合，所制备的面膜，可完美贴合任意脸型，即可配合其他美容产品如药物面膜使用，促进药物和/或水分的吸收，也可单独使用，促进组织新陈代谢和自我修复，起到消炎、止痛、消肿、促进愈合的作用。所制备的可拉伸温热物理面膜，可卷曲收藏，携带方便，操作简单；制备工艺简单，其分形结构可通过多种方式实现，同时，面膜制备成本低廉，易于实现大规模生产。
此外，作为上述各实施例的优化，为了降低电源功率进而降低电源的尺寸和重量，可以对可拉伸柔性电路板划分区域，各区域电路上不联通(但可以公用阳极或阴极)，控制电路周期循环地切换通道以对各个区域供电，在一个时间段只对某一区域供电。
显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
