Samsung’s Simband represents the company’s shift from fitness tracking to health monitoring, allowing medical startups and researchers to develop sensor applications.

Simband is equipped with six sensors: electrocardiogram, photoplethysmogram, galvanic skin response, accelerometer, and thermometer. Developers can also add proprietary sensors.

The wearable’s three main functions are called “trends,” “monitor,” and “spot check.” Trends displays one’s data over time, monitor is a real-time, all sensor tracking mode, and spot check quickly checks heart rate and blood pressure.
