The latest and most complete smartwatch from Fitbit is the model Sense, characterized by incorporating the first electrodermal activity sensor (EDA) to manage stress. To this is added an innovative technology for monitoring the heart rate, a new application that performs electrocardiograms (ECG), and a sensor skin temperature. With these features Sense is configured as a smart watch specifically designed for the control of health and fitness. The model is powered by a battery with an autonomy of more than 6 days.
As featured services, the company has announced a six-month free trial of the Fitbit Premium service, which makes it possible to track variability in heart rate, respiratory rate, and blood oxygen in the new dashboard. Health Metrics developed by the brand.
‘Our goal is to make the world a healthier place, and it has never been more important than these days. Covid-19 has shown how crucial it is to take care of physical and mental well-being, ‘he said James Park, co-founder and CEO of Fitbit. ‘Our products and services combine advanced sensor and algorithm technology to reveal health information. We are breaking new ground for wearables, helping to understand and manage stress and cardiovascular health, combining key Health Metrics in a simple and accessible way to monitor skin temperature, heart rate variability and blood oxygen level. Most importantly, we offer new data that can only be obtained in the doctor’s office once or twice a year, helping to improve holistic health and well-being in these times when it is most needed, ” he says.
Stress is a general problem, one in three people suffers a lot of worry or stress, as well as derived psychological and physiological symptoms. This situation can lead to health problems if it is not controlled, such as high blood pressure, cardiovascular disease, obesity, diabetes and mental health disorders, such as anxiety or depression. Sources from the Fitbit company point out that the use of new technologies integrated into simple devices, such as Sense, makes a Helpful tool and insight into the body’s response to stress, and thus favor its control. This stress management capacity has been developed by the company’s team of mental health experts, who already have years of experience in its diagnosis and treatment, together with the advice of specialists from various academic institutions.
The new sensor EDA integrated into the Sense measures electrodermal activity. Placing the palm of the hand on the device, it detects small electrical changes in the skin, helping to understand the body’s response to stressors, to help control them. The device allows for a rapid electrodermal exam to see reactions, or combined with guided sessions of Mindfulness in the Fitbit app, to see how your body reacts to meditation or relaxation. At the end of each session, an electrodermal response graph is generated in the device and in the mobile application, to assess the progress made over time and to be able to reflect on the level of emotional stress of each person.
The metric Management level calculates the amount of daily physical stress in relation to heart health data, sleep, and activity level, adding suggestions to reduce it. With a range of 1 to 100, the highest score being the fewer physical signs of stress the body presents, the Management level of stress is accompanied by recommendations to better manage it, such as breathing exercises and other Mindfulness. Fitbit Premium members will be assisted with a detailed breakdown of how this level of stress management is calculated, consisting of more than 10 biometric inputs, including effort balance (activity impact), capacity response (heart rate, heart rate variability and electrodermal activity recorded by the EDA Scanner application) and sleep patterns (sleep quality).
The section dedicated to Mindfulness in the dedicated application it is accessible to all users and in it you can set a weekly goal of Mindfulness and reminders, reflect on stress and record mood after sessions.
Fitbit has made continuous heart rate monitoring possible since 2014, through the feature’s launch earlier this year. Minutes in Active Zone. Now, this scenario is enhanced with an EKG app that analyzes the heart rate for signs of atrial fibrillation. To know the personal data, it is enough to place your fingers on the steel ring that surrounds the sphere for 30 seconds and receives a reading that you can download to share with the doctor.
This is possible thanks to technology PurePulse 2.0, with a multi-path heart rate sensor and an updated algorithm. It incorporates an important function for cardiovascular health: custom alerts in case abnormally high or low frequencies are detected in relation to personal limits.
Tool to improve well-being
Beyond being able to detect heart conditions, the device unveils new health measurements in the mobile application, which indicate trends and changes in physical condition. It incorporates a new skin temperature sensor to detect changes that may be symptomatic of fever, illness or the beginning of a new menstrual cycle. Unlike a momentary temperature measurement, this sensor monitors the variation during the night to better identify small changes over time, so that it is evident when something is out of your usual pattern.
Panel Premium Health Metrics monitors respiratory rate (mean breaths per minute), resting heart rate (an important indicator of cardiovascular health), heart rate variability (variation in time between beats), and variation in skin temperature. It also provides data on SpO2 (blood oxygen) levels.
Fitbit Sense includes health and fitness features such as built-in GPS, about 20 exercise modes on the device, automatic activity monitoring with technology SmartTrack, aerobic capacity level and score, as well as advanced tools around sleep.
Add smart capabilities, like the integrated speaker and microphone to answer calls and texts thanks to the voice assistant of Google or Amazon Alexa.
Fitbit Sense has been created using design processes such as miniaturized nano-molding and laser welding on carefully chosen materials. Finishes are physically and visually lightweight, with aerospace grade aluminum and stainless steel. The new infinite straps are flexible and comfortable, offering a proper fit for better sensor performance, while the quick-release closure makes it easy to change lalso. The robotically manufactured body fuses glass and metal and employs the same production techniques used in submarines, resulting in a water resistance up to 50 meters. The internal biosensor suite has been configured to house more sensors and intelligence than on any other Fitbit device, while maintaining current aesthetics and long battery life.
Screen and interface
The AMOLED screen has a built-in ambient light sensor that automatically regulates it for easy viewing. It has the always-on display mode and the panel is responsive, with a brighter image and higher resolution.
The user interface and processor have been completely redesigned, offering intuitive and efficient navigation. This includes the introduction of widgets customizable, redesigned notifications and clean-looking on-screen apps. Allows you to customize your favorite tools and shortcuts.
Fitbit Sense is available for about 330 euros in carbon black / graphite stainless steel, and ivory white / gold stainless steel.
