今天看到有人在 V2 发帖询问无线充电对健康的影响，看了下无线充电频率，发现还真的有点意思。

100-300 kHz 电磁波会干扰有丝分裂过程，在细胞分裂的最终阶段使细胞器和后含物发生电泳，这意味着它可以杀伤正在分裂的干细胞或减数分裂的生殖细胞，但它同时也会抑制癌细胞的分裂，所以现在有的医院会用 150-200kHz 频段的电磁波治疗脑瘤、脑癌，利用的是脑内正常细胞不经常分裂，以及肿瘤 /癌细胞分裂较为频繁的特点。

无线充电：根据 QI 标准 1.2.4，发射端根据频率变化可以分为定频架构与变频架构。变频架构的工作原理是通过改变工作频率从而调节发射功率，改变的频率一般在 100-205kHz。定频架构，如苹果 MFi 认证的 7.5W 快充工作频率则固定在 127kHz 左右。

顺便说下据我所知的其它频段电磁波的影响，高频电磁波，譬如 X 射线，伽马射线，可以把 DNA 打断，所以对人体有害，不过同理也可以用伽马射线来治疗癌症病灶。紫外线频段的电磁波，剂量够大的情况下可能导致皮肤癌。可见光频段的电磁波，强度够大的话可能导致人眼失明。红外线频段的电磁波，强度够大的话会导致表面灼伤。微波频段的电磁波，强度够大的话会导致体内灼伤。

谢谢 4 楼提醒，发现忘了写场强范围了，场强范围 1~3V/cm

从功率来看应该问题不大，1988 年颁发的中华人民共和国国家标准 UDC 614.898.5 GB 9175─88 环境电磁波卫生标准，长中短波的场强都要求不超过 25V/m，只要无线充电器能兼容这个标准，就达不到电场疗法的杀伤范围。
