Recent iWatch rumors have reported that Apple’s iWatch will boast 10 or more sensors, but many are left to wonder what those sensors are and what they will do. Seeing as 10 sensors is a lot to try and fit into a device so small, it will be interesting to see what Apple has up their sleeve. For now, we can almost guarantee that many, if not most, of the sensors will have to do with some type of motion tracking since Apple is expected to integrate health and fitness tracking into their new wearable.
TechHive asked Hamid Farzaneh, CEO of Sensoplex (a Silicon Valley company that designs and supplies sensors for the increasing wearables market), to speculate the most likely sensor candidates for Apple’s iWatch.
Most likely candidates
An accelerometer is a device that measures non-gravitational accelerations. To put this into perspective, on the iPhone there is an accelerometer, which is used to determine the iPhone’s physical position. The accelerometer can tell when the iPhone is tilted, rotated, or moved. Accelerometers can also measure body movement to track the steps you take and your sleep patterns.
A gyroscope is a device for measuring orientation and rotation. Gyroscopes can sense when you turn your wrist to look at your display, thus waking up your display.
Magnetometers are compasses and can be used to improve accuracy in motion tracking.
Barometric pressure sensor
The barometer can measure changes in altitude as well as provide the user with weather information and data. For a runner or cyclist, this sensor would come in handy for climbing hills and such.
Ambient temperature sensor
Ambient temperature could be compared to skin temperature to determining exertion levels and exercising patterns.
Heart rate monitor
This sensor does exactly what it says it does, measures your heart rate. This would better integrate Apple’s HealthKit into the much rumored wearable.
The oxymetry sensor measures blood oxygen, which records accurate pulse and heart rates.
Skin conductance sensor
This sensor measures how much you sweat and would aid in calculating exertion levels, and thus data on calories you’ve burned.
Skin temperature sensor
When you compare skin temperature to ambient temperature, you can get a better idea of your exercising patterns and exertion levels.
This is another quite obvious sensor that will likely be integrated into Apple’s iWatch. Of course, the GPS would determine your current location as well as the location(s) you’re traveling to and the location(s) of where you’ve been.
