Although some smart clothes have been steadily gaining popularity, the trend has yet to really take off. However, there’s now a new health tag that turns any wearable into a piece of smart clothing, and it may help the tech textiles go mainstream.

The Spire Health Tag is a small adhesive device that can be discreetly attached to any piece of clothing, be it a collar, a sleeve, or the side of a bra. The high-tech tag offers real-time information about a wearer’s heart rate, stress levels, and sleep patterns, and uses all of that information to develop a view of overall health.

The Health Tag collects 20 billion data points a day and utilizes special algorithms. What makes the tag really stand out from its competitors, though, is its ability to measure calmness and stress levels, allowing its wearer to understand causes and triggers.

Spire’s new product is a unique way to live a healthier life and is a great option for those who aren’t interested in a smartwatch. The Spire Health Tag is available in a set of three for $99, as a pack of eight for $199, and as a set of 15 for $299.
