I’m thinking of ditching my Apple Watch for this solar and body heat-powered band


In the seven years I’ve been wearing an Apple Watch I’ve rarely worn an analog watch, which is a shame, because I’m a watch collector and I have drawers full of classic timekeepers. I do miss them, and I also wonder if all the real-time information that Apple is constantly sharing with me is necessary. Maybe BHeart’s new smart band/bracelet is the answer.

BHeart unveiled its solar and human activity-powered BHeart smart band at CES 2023 in Las Vegas. It caught my eye because it attaches to virtually any classic watch using what’s known as ‘lugs’ – basically the pins that connect a typical watch band to the watch body. The band, which comes in silver and gold, is attractive enough, but it’s also packed with technology.

In addition to activity and health-tracking sensors on the inside of the band, including a Photoplethysmography (PPG) sensor for measuring heart rate, this may be the first fully self-powered smart watch band. On the outside of the band are five square solar panels, which work in tandem with a heat receptor to collect energy for the tiny 1mAh battery.

That’s apparently all the energy the band needs to track the aforementioned heart rate, activity, steps, and sleep score.
