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.
Apple says that the technologies developed over the years have enabled the use of such sensors on wearable health devices. It mentions these enabling technologies as "system in package, embedded die and semiconductor very-large-scale integration (VLSI)."
The patent talks of two different types of temperature sensor packages. One where the sensor touches the skin of the wearer and another where no skin contact is necessary.
While the underlying working of both the sensors are the same, the difference would decide where the sensor would be placed in the housing device. If it is a touch-based sensor, it would be placed at the surface of the device, else it can be embedded away from the surface.
The patent application focuses more on the working of these sensors in a device than revealing which devices these will be used on in the future. The possibilities mentioned, however, assure that the Apple Watch can be using such technology once it is ready.
Since both the technologies will enable temperature reading from a device, Apple can easily sway both ways for embedding such an ability on its Apple Watch. Though it has been confirmed that the Apple Watch Series 7 this year will not feature the functionality. A recent report has hinted at its arrival in the next year's Apple Watch iteration.
