A recent rumor suggests the Apple Watch Series 12, expected this fall, could integrate a health sensor directly into its silicone bands. Leaker Kosutami claims this sensor would be injection-molded, and that Apple has not yet figured out how to embed such technology into bands made from other materials. The exact function of this sensor remains unspecified.

This isn't the first time band-integrated sensors have been discussed for the Apple Watch. Apple has filed numerous patents over the years for modular band links and smart bands capable of housing various sensors, including those for blood pressure and hydration. However, none of these patented concepts have yet materialized into a consumer product.

Kosutami's track record is inconsistent, and this specific rumor is uncorroborated. While Apple's extensive patent activity indicates a strong interest in this area, users should approach this particular leak with caution. The Series 12 is anticipated to be a minor update, likely focusing on a new chip.
