A recent leak has revealed that the Apple Watch Series 10 prototype featured innovative health sensors that were not included in the final release. The prototype, showcased by leaker StelleFudge, displays a unique arrangement of sensors aimed at enhancing health monitoring capabilities. This version also runs on an unreleased build of watchOS 11. Although Apple had previously worked on advanced sensors, including those for blood pressure and glucose, they were ultimately postponed for future models. This decision follows legal challenges faced by Apple concerning its health sensor technologies.
