Wristify by Embr Labs uses all-natural waves of coolness or heat to activate the thermoreceptors on the surface of your skin, leaving you feeling rejuvenated. It gently glows blue when cooling you, and glows a warm orange while heating you up. Just press the button to turn it on, and it will give soothing waves of heating or cooling to the inside of your wrist. Embr Labs was founded by four MIT students who are passionate about finding ways for people to take control of their own comfort. After winning the first prize of the MADMEC competition at MIT, we decided to go forward and make the Wristify bracelet a reality. At Embr Labs, we are driven by a shared belief in the importance of connecting mind, body and environment. Using our patent-pending technology, we're working hard to make a piece of jewelry that actually does something. In fact, we think it will change how the world thinks about wearables and comfort.
