Just how many sensors can you cram into a tiny watch?
Wrist-Mounted Sensors
The Apple Watch is alreadybristling with sensors.
I dont think smartwatches will be accurate enough to use for medical purposes.

The benefits of all this monitoring are clear.
And it can also warn you of problems and even take action.
Ditto for determining your gait using algorithms.

But for other sensors, the wrist isn’t a good spot.
After all, the nurse doesn’t press their thermometer to your wrist when taking your temperature.

And in fact, Apple has had trouble adding more sensors to its devices.
The next AirPod Pros were also rumored to include temperature and heart-rate sensors, but that plan ison hold.
Apple’s innovation comes from a combination of hardware and software working together.
This is something Apple is very good at, but there’s only so much you could do.
Even the best algorithms need good raw data, and for that you need sensors.
Technically, the Apple Watch is already a marvel.
It can do so much and manages to do it all day long on a tiny battery.
And that’s just fine, because the Apple Watch is already perfect for most people.
