Apple has been working on temperature sensors for Apple Watch since 2019, patent reveals

Apple has since long been working on temperature sensor packages that work both with or without contact with the user. Apple Watch might make use of the same soon.

The yet to come health features of the Apple Watch are more than confirmed at this point with several developments pointing in one direction. The question that still looms is the timeline that the Cupertino tech major will follow for these upgrades. A new patent application hints it might not be long before we see one such feature on Apple Watch. Temperature sensors to measure the body temperature of the wearer is a major upgrade that the Apple Watch is expected to get. A patent application made public recently shows that Apple has been working on the technology since 2019. Under the name "Packaging Technologies for Temperature Sensing in Health Care Products," the patent describes “temperature sensor packages and methods of fabrication” for making this possible. Among the wide variety of use listed for the technology, “wearable health devices” is one.
