Samsung's Simband, now in its second generation, is a wearable gadget that keep tracks of your vitals.

Unlike other smartwatches and fitness bands, the Simband is not available to the public; it's still in beta testing. It's built for developers and the medical industry, so you won't find one on store shelves anytime soon.

Packed with medical sensors, the Simband measures your step count, like the Jawbone Up and the Fitbit. That data shows up on the device's small screen.

The Simband also has sensors to track your heart rate while you wear it.

Other sensors on the Simband can measure your blood pressure and skin temperature.

Those metal plates you see on the band are the sensors that measure your biometric data.

The lights also help gather data on your body's activity.

The Simband fits around the wrist and clasps in place. The entire system is sweatproof.

Though Samsung hasn't revealed too many details about it, the device is meant to be used in the medical field, possibly for patients who need to track their vitals for medical conditions.

Developers now have access to the APIs and SDK for the Simband, so they can start looking for ways to make sense of the data it collects.
