Fitbit (FIT), which is in the midst of being acquired by Google (GOOG, GOOGL), announced three new wearables on Tuesday, including its most advanced smartwatch yet.

The watch, called the Fitbit Sense is designed to track everything from your body temperature, to your heart rate and rhythm, to your sleep, and even your stress levels using a built-in electrodermal activity (EDA) sensor that can tell when you’re starting to sweat before you even realize it.

“I think one of the important things to take away from our fall launch is that it really underscores our continued evolution of being a pure fitness tracking company to a health company,” Fitbit CEO James Park told Yahoo Finance.

“And it’s really the culmination of a lot of the new sensors that we’re bringing into the fall products, and then also the software experiences on top. So we’re obviously really excited about our EDA sensor. It’s the first in its class; it took a lot of R&D to get to this point,” he added.

And it’s that kind of work that Park said is what he believes drew Google’s interest in the first place.

Making ‘Sense’ of stress

The Fitbit Sense, which is available for pre-order today for $329 and launches in late September, is Fitbit’s most advanced smartwatch to-date. It features a redesigned body and a larger display that the company says is nearly edgeless.

The Sense’s stainless steel frame features two electrodes that you cover with your hand when you want to use the EDA sensor to begin measuring your stress level. According to Park, the EDA sensor sends a microcurrent through your skin to measure the change in electrical resistance as your palm sweats. The more you sweat, the more stress you’re likely under.

You could use that information to recognize that you should meditate or try breathing exercises to help lower your stress in the moment, and over time, determine what best lowers your stress most.

There’s also a new Stress Management feature in the Fitbit app for Sense users, which provides you with a Stress Management Score calculated using your heart rate, sleep, and activity levels. The score is based on a 0 to 100 scale with higher numbers being better and lower numbers worse.

The company says its Fitbit Premium members will also get detailed breakdowns of their scores based on things like heart rate, heart rate variability, electrodermal activity, impact of physical activity, and sleep patterns.

Park says that there’s been a greater interest in stress mitigation since the coronavirus pandemic took hold, which makes the Sense’s EDA and the company’s Stress Management feature more relevant.
