Other wearables like the Fitbit Sense, Sense 2, and even Manchester City’s forthcoming smart scarf also feature EDA sensors as a means of tracking stress or emotion. The exercises can all be completed in-app and are simultaneously tracked by the ring itself as you complete them. Those exercises include activities like breath work, meditation, and cognitive behavioral therapy-based journaling. “And we take all that data and personalize exercises for you that are scientifically proven to help manage your stress and improve your mood and overall wellbeing.” Rad also added that, from a security and standards perspective, the device is HIPAA compliant but didn’t go into further detail regarding Happy Health’s privacy policy and how data is stored. “We tell you about your mood on an ongoing basis so you understand when you’re calm, alert, or tense,” says Happy Health and Tinder founder Sean Rad. The ring then continually adjusts the AI model to an individual person’s data, as opposed to comparing that person’s data to a predetermined user set. “EDA sensors measure the electrical changes that occur on the hand in response to the small amounts of sweat that start to be produced on the palm of the hand.” Freckleton went on to explain that Happy Ring’s EDA sensor then looks for sweat gland openings or sweat production, which is then fed into an algorithm that identifies your emotional state. “As we start to have difficult thoughts or experience strong emotion, our brain responds to help us respond to that stimuli,” says Dustin Freckleton, a medical doctor and Happy Health CEO. Essentially, the device works by detecting when your sympathetic nervous system - the thing that regulates your fight or flight response - starts raring up.

The Happy Ring, which just received $60 million in funding, features a custom electrodermal activity (EDA) sensor that monitors changing stress levels in real time. Instead of dubious color-changing stones, it has created the Happy Ring, which aims to alert users about their mental health using biometric sensors and artificial intelligence.

Startup Happy Health is looking to give the mood ring a “smart” makeover.
