I'm designing a wearable device, and I'm looking for resistant materials, different from metals, that are safe to use on the skin. According to Wikipedia PTFE (teflon) is not harmful. Could someone recommend materials to protect the electronics from sweat/dirt and the skin from the device silicone?

Well, teflon is a "forever chemical" (PFAS) and the consensus seems to be it's not wonderful if it gets inside of you [1]. Silicone is a PFAS alternative and a little safer, but also not wonderful if it gets inside of you [2]. All of which is to say that your device should be OK as long as no one puts it inside them. AFAIK anyway. [1]: https://www.cancer.org/cancer/cancer-causes/teflon-and-perfluorooctanoic-acid-pfoa.html https://www.cancer.org/cancer/cancer-causes/teflon-and-perfl...
