Future Apple Watches may have even more health-related sensors

FIG. 1A shows a perspective top view of an example wearable device having sensors for determining a health parameter of the user of the wearable device.

Apple has applied for a patent (number US 20230064273 A1) for “sensing health parameters in wearable devices.” It hints at even more health sensors in the Apple Watch.

About the patent filing

Sensors are included in many of today’s electronic devices, including electronic devices such as iPhones, Apple Watches, iPads, Mac laptops, and other devices. Apple says that, given the wide range of sensor applications, any new development in the configuration or operation of a sensor can be useful. 

New developments that may be particularly useful are developments that reduce the cost, size, complexity, part count, or manufacture time of the sensor, or developments that improve the sensitivity, functionality, accuracy, or speed of sensor operation. It is increasingly desirable to have more accurate and reliable measurement sensors in wearable devices, and to have measurement sensors that are lower cost.

Summary of the patent filing

Here’s Apple’s abstract of the patent filing: “Embodiments of this disclosure are directed to a wearable device having a housing, a display, and a sensor system. The display is at least partially surrounded by the housing. The sensor system is housed at least partially in the housing. The sensor system includes a first sensor, a second sensor, and a controller. 

“The first sensor is configured to contact a body part of a user and generate a first signal. The second sensor is configured to sense a mechanical wave in an ambient environment of the wearable device and generate a second signal. The controller is configured to generate a resultant signal by removing noise from the first signal using the second signal, and determine a health parameter of the user from the resultant signal.
