Description

一种应用于穿戴设备的电极制造方法 技术领域
本发明涉及一种电极的制造工艺，尤其是一种应用于穿戴设备的电极制造方法。
背景技术
生命过程中的新陈代谢和一切活动都产生电，外界刺激、心脏跳动、肌肉收缩、眼睛开闭、大脑思维等，都伴随着生物电的产生和变化。生理学研究表明生物电并不是器官或器官机能活动的副产品或伴随物，而是细胞实现一些重要生理机能的关键或决定因素，特别是神经元给出的肌电信号刺激肌肉做出响应，使肌肉系统产生对骨骼系统的作用力以完成各种机械动作。
由人体自身发出的生物电信号，如上述的心脏跳动(心电信号)、肌肉收缩(肌电信号)等，由电极收集、滤波、放大进行后续的分析。
外界也可以经由电极将电施加到人体，高压电脉冲应用如心脏除颤器，低压电脉冲应用如电子肌肉刺激(EMS)技术，可以刺激肌肉使肌肉做出收缩响应达到锻炼肌肉的效果。
其中EMS技术中的电流，其频率同时包含了中频和低频，并将电极成对地围绕肌肉群布置，无论对表层和深层肌肉，还是快肌、慢肌，都能在电信号下同时“全体动员”参与运动，而且可通过一定的频率波包，使得肌肉快速地收缩放松，取得靠人本身神经系统都远远达不到的锻炼效率。随着EMS技术进步，其不但应用于专业运动领域，而且迅速向普通人日常锻炼的市场开拓，按照一般人的使用体验，市场急需一种能覆盖全身的电极穿戴装置，电极和电线都贴合身体，电流发生器小型可携带化，通过无线蓝牙进行控制，其电极能充分贴合身体轮廓，电流分布均匀不产生局部尖端放电刺激人体，连同电流发生器和电极之间的电线有良好的弹性和舒适性，符合人体自由运动的需要。
随着材料科技的发展，现有自带电极的穿戴式设备中常用的电极装置，如将碳纤维编织成较为致密的网状结构，以形成接触人体的电极，但是由于碳纤维易脆的材料特性，使得电极寿命短、不耐洗；或如将导电材料涂在高分子材料基底上，进而形成电极，最常用的为在织物上采用化学镀银，如中国专利申请CN101536903A(申请号为200910064618.3)所公开的一种穿戴式心电电极装置及其制造方法，包括步骤有：按照衣着的图样裁剪衣着；以复合纤维为基材，将纳米银层镀在复合纤维上，把制成的电极设置在衣着的相应位置，银对皮肤亲和，并有杀菌效果，但是这种电极，其洗涤次数仍相当有限，耐水洗性能差，而且更重要的是，在人体运动时的身体曲面变化伸展时不能保证整个电极面对身体的贴合，从而使得身体电流回路的阻抗不断变化，会造成电流刺痛或灼伤，市场急需要新颖的电极来实现这些要求。
同样，连接电发生装置和贴合身体各个部位的电极需要有弹性的、外部绝缘的、低阻抗的、和皮肤亲和的电线。

附图说明
图1为本发明的方法制造的电极的结构示意图。
具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
如图1所示，本发明的应用于穿戴设备的电极，包括依次设置的镀银布1、薄膜2、弹力层3和基层布4，复合而形成电极，基层布4用于连接固定(通常通过缝合的方式)在衣物内侧，镀银布1贴合人体肌肉。
上述电极的制造方法为：
1)制作镀银布1：在工业应用中，导电材料有很多种类，主要为各种金属，其中贵金属如金和银，导电性能尤其优异，因此，在本发明中，选用尼龙纤维加氨纶织造弹力织物(经编，纬编或机织物)。
在本实施例中，为超细尼龙纤维加氨纶织造成紧密的高弹性经编织物，超细尼龙纤维是指微米(约1～2微米)级的化学纤维，其特点是导电点之间线圈排列连接紧密，表面电阻小，在任何情况下电极内部不会形成局部电势能差；
在此弹力织物的基础上做化学镀银(涂布银胶)处理而得到镀银布，可替代的，镀银布1也可以采用背景技术中所述的，先在尼龙纤维表面镀银，而后再编织成弹力织物，还可在此弹力织物的基础上再次进行镀银；
2)粘合薄膜2或粘性高分子材料：在镀银布1上先用点涂方式粘合一层薄膜2或粘性高分子材料，在本实施例中优选为薄膜。薄膜2可以改善对汗水的收纳，让汗水表面迅速渗开，使得皮肤出汗后阻抗降低更快，更快使内部身体组织和外部电极低阻抗的接通，配合电发生器，使用体验更好；同时还可以对镀银布1的线圈底层进行固化，大大降低在洗涤过程中物理接触点位置银的丢失，确保在经过多次水洗后线圈之间仍能保持良好的物理接触，提高耐洗性；
3)复合弹力层3：在薄膜2上用火焰方式复合弹力层3得到复合后的电极布；弹力层3可使得即便在人体运动过程中仍能保证电极与人体皮肤良好的贴合。
本实施例中优选为海绵，海绵的厚度根据需要可选的为2.0～8.0mm；可替代的，也 可以选用空气层、蜂窝结构织物等；
4)复合基层布4：为起到对电极的整体保护，并降低穿戴后与皮肤摩擦产生的噪声，电极布最后可以再用点涂或火焰方式在弹力层3上复合一层弹力面料作为保护用的基层布4；
5)切割成形：将步骤3)或步骤4)得到的电极布根据需要的尺寸切割后作为穿戴设备的电极使用，得到的电极具有电阻率低，耐水洗，导电均匀，贴合紧密舒服，较快收纳汗水后低阻抗地连通内部身体组织的特点。
可选的，根据不同的需要还可以在薄膜2和基层布4之间粘合或复合网孔布。
对上述方法制造的电极进行耐水洗性测试：
(一)试验条件
1、洗涤条件
①参照标准GB/T 8629-2001《纺织品试验时采用的家庭洗涤及干燥程序》(与ISO6330：2000《纺织品一一纺织试验用家庭洗涤和干燥程序》等效)；
②使用水平滚筒、前门加料型洗衣机(A型洗衣机)；
③干燥程序采用F-烘箱干燥，烘燥温度为60℃±5℃，烘干时间如为25min；
④陪洗物：无；
⑤洗涤程序：5A；水温：常温；洗涤时间15min、漂洗18min、甩干2min
⑥洗涤剂：无磷ECE标准洗涤剂(不含荧光增白剂)，用量为每次洗涤66±1g。
2、试样准备
裁剪电极布，裁剪规格为18cm×18cm(根据剥离强度测试试样规格和电极布用于服装时的裁剪尺寸确定)，得到试样电极，为避免在水洗过程中试样沿边缘剥离，试样应进行锁边处理，以模拟电极在服装上应用时的封边效果。
(二)试验操作
1、按照洗涤条件设置滚筒洗衣机洗涤程序并准备好试样进行洗涤：
2、在每次洗涤后，注意观察各试样的外观变化(是否开始出现剥离试样，是否出现大量剥离试样，以及洗涤到几次时出现剥离试样的块数及比例)，作为评价电极布剥离性能的定性依据；每洗涤5次，取各编号试样1块分别测试其经向(长度)剥离强度及导电性能；导电性能测试后的试样进行二次裁剪，进行剥离强度测试；
3、每次取样测试后(洗涤5次的整数倍)，为了保证洗涤条件不变化，需要补充同等数量、规格的试样进行洗涤，即取出一块试样就要补充一块试样；
4、根据测试结果，汇总电极布剥离性能和导电性随洗涤次数变化情况的数据。
(三)试验结果与分析
电极导电性测试试样有效规格为15cm×5cm(试样宽度5cm，两端夹持线间距离为15cm)，将所有经一定水洗次数的待测试样置于恒温恒湿箱中，设置恒温恒湿箱的温湿 度为标准大气条件(T＝20℃，RH％＝65％)，平衡12小时以上，再进行测试。
将电阻计两极短接，按设定操作方法扣除线路电阻。由于在测试待测试样电阻时，基本都出现电阻值随时间持续衰减的现象(衰减速度越来越慢)，因此约定极化时间为30S，即用夹持器夹持待测试样30秒后，读取电阻值，虽然此时电阻值仍在衰减。
每种试样的测试次数为3次，试样裁剪方向为纵向(经向)，测试结果见表1。
Figure PCTCN2016000125-appb-000001
表1：电极试样导电性测试
从上表1中可知，在水洗45次后，表面电阻仍以减缓的速度增加，总体来说导电性能保持非常良好，能满足长期重复洗涤后的功能保持。
