Introducing the Lief smart patch, a device designed to initiate calming exercises when heart and breathing rates show elevated levels of stress. Lief helps individuals by focusing on their heart rate variability(HRV)—the amount of time between each heart beat- and how it relates to breathing cycles. Whenever the patch senses a stress response, it quietly vibrates to help the person sync their breath over the course of three minutes. By doing this, stress can be lowered significantly. The device is currently being funded on Kickstarter, and could be available as soon as July 2017.
