Soon it might be just as common to track your emotions with a wearable device as it is to monitor your physical health.

Wearable technology already can tell you about your heart rate, sleep patterns, health habits and breathing patterns; all of which can provide just as much insight into your emotional state as your physical state. For example, one Fitbit wearer discovered his device recorded the moment of his breakup. His heart rate soared at the bad news and stayed elevated for the rest of the day as he dealt with the sadness and heartache, showing how closely his emotions affected his physical state.

But now, more wearables on the market are designed specifically to monitor your feelings, not just your physical state. These devices work by measuring everything from breathing and heart rate to speech patterns and brainwaves. Armed with information, you learn to recognize your emotional states and learn how to soothe your reactions and control your responses.

Beyond Verbal

By analyzing voice patterns, Beyond Verbal captures your mood as well as the mood of other people you’re talking with. It isn’t a stand-alone device but instead works an API that can be added on to existing apps, devices or systems.

Emotiv Insight

This sci-fi headgear will make you think of the Star Trek Borg. The Insight actually records brainwaves and interprets the results to tell you about your brain’s activity, such as your level of attention, focus, engagement, interest, excitement, affinity, relaxation and stress. Even more amazing, the Insight allows users to use their own brain to control devices such as wheelchairs, remote control cars or computers.

Empatica

The Empatica E4 wristband device monitors any changes in your skin that can indicate stress, emotions and excitement. It also monitors your heart rate and can track your motions. In addition, you can tag events and review your body’s reaction to them.

MUSE Headband

This is another headband device that monitors brain signals but it’s designed specifically to help you reduce stress and generate a calm state of mind. Use it with a guided meditation app to train yourself to quiet your mind. The MUSE headband app uses the sound of wind to give you instant feedback: you’ll hear a gentle breeze while you’re calm but the gusts will increase if your brain activity increases.

PIP

Hold your thumb against this small hand-held device to measure your stress levels. The PIP works by registering your skin’s electrodermal activity. Use PIP along with one of the companion apps to teach yourself how to slow down and restore a calm state of mind.

Spire

This clip-on device monitors your breathing rate to detect when you’re tense or stressed. When Spire senses you’re losing your cool, the companion app provides you with guidance and exercises to calm your mind.
