Hi,
this is the research: https://pubs.acs.org/doi/10.1021/acs.estlett.4c00907?utm_source=syndication
You need to pay to read the full article, but these are some finding: https://www.yahoo.com/lifestyle/research-finds-smartwatch-band-laced-011943246.html
The bands tested as part of the chemical analysis include those offered by big names like Google, Samsung, Apple, Fitbit, and CASETiFY. Interestingly, Samsung and Apple both sell watch bands made out of fluoroelastomers, the core problematic chemical at the center of the research, and even mention its “benefits” on their websites.
This is unfortunately true if you read this article: Wearing your Apple Watch - Apple Support (CA)
What's in the bands
These are the Apple Watch band materials that come into contact with your skin:
- Ocean Band: Fluoroelastomer with titanium
- Sport Band: Fluoroelastomer with stainless steel, ceramic, titanium, or 18-karat gold
Fortunately I never used it. I just ordered one, but I am trying to cancel the order.
