Apple is looking not just at maximizing the efficiency of health sensors in the Apple Watch, but also minimizing the space they take up by creating curved sensor elements to fit better in the enclosure.
A new patent application from Apple is chiefly concerned with the specifics of how certain sensors could be deployed within the Apple Watch. However, ultimately it’s really about ways to make the Watch thinner.
“It can be challenging to incorporate sensors such as optical sensors [which measure heart rate] into electronic devices,” says Apple in “Electronic Devices Having Optical Sensors With Curved Laminated Films.”
