Fitbit has introduced a new health smartwatch that includes what it claims is the world’s first electrodermal activity (EDA) sensor to manage stress.

The Sense smartwatch includes a new electrocardiogram (ECG) app, advanced heart rate tracking technology and an on-wrist skin temperature sensor powered by a six day battery, the company said. The smartwatch can help users track trends in health and well-being such as heart rate variability, breathing rate and oxygen saturation of arterial blood (Sp02).

The EDA sensor measures electrodermal activity responses. To use the sensor, users place a palm over the face of the device to detect small electrical changes in the sweat level of the skin. Measuring EDA responses can help to understand the body’s response to stress and helps to manage stress.

The smartwatch also features 24/7 wrist-based heart rate tracking with an ECG app to assess heart rhythm for signs of atrial fibrillation. Users can operate the device by holding fingers on the corners of the smartwatch and after 30 seconds a reading is shown that can be downloaded in order to share with doctors or other professionals.

Additionally, Fitbit has introduced the Fitbit Versa 3, a smartwatch that features on-device GPS, in-app workout maps, enhanced PurePulse 2.0 technology and tracking of fitness goals. The smartwatch includes Google Assistant as well as Amazon Alexa built in to set workout reminders, check the weather, add to a shopping list, control smart home devices and more through voice control.
