According to 91mobiles, a smart bracelet patent from Google has recently been approved by the US Patent and Trademark Office. The biggest feature of this bracelet is that it does not contain any screen, only has a sensor and charging electrodes inside.
The name of the patent is “Wristband Tracking Fitness Status”. According to the patent description, the bracelet can rely on sensors to track all your health activities, but the data cannot be viewed directly on the bracelet. It can be seen from the patent application drawing that there is a similar optical heart rate sensor component at the bottom, as well as a circular charging electrode.

The body of the bracelet is very thin. The inside is covered with anti-slip lines, and only the sensor part protrudes from the surface. This is to make it easier to wear it firmly during fitness and exercise. The body of the wristband sensor does not seem to be removed from the wristband. So the material of the wristband needs to be very durable and washable. In addition, there does not appear to be any microphone opening on the bracelet, and the user will not be able to directly control the bracelet in any way.
Prior to this, some companies had launched non-screen bracelet products. Among them, we can mention Amazon’s Halo which is challenging the Apple Watch and Fitbit.
Amazon’s bracelet cannot be purchased separately. It can only be prepaid for 6 months of Halo + subscription service, and the prepaid price is $64.99. After that, users have to pay a monthly fee of $3.99 before they can continue to use it.
