There’s no shortage of cheap fitness and activity trackers which you can wear on your wrist or clip to your shirt, belt, or pocket to keep track of your daily step count, distance traveled, and other stats.

But Toshiba’s Silmee line of health trackers go a bit further. Earlier this year the company introduced a Silmee device that can measure skin temperature, heart rate, motion, sleep quality, and more. It’s aimed at researchers and medical professionals and offers more precise measurements than a typical consumer device: the heart rate sensor actually has electrocardiogram functionality.

Now Toshiba is showing off a few new wearable health trackers that you can wear like a wrist band.

The Silmee W20 features activity, sleep, and pulse rate detection. It can also measure ultraviolet light.

Toshiba also has a model called the Silmee W21 that features built-in GPS.

Both models can send data to a smartphone app.

Toshiba is introducing its new wearables in Japan. It’s not clear if they’ll be available in other regions anytime soon.
