Lumia Health, the world's smallest wellness wearable, the Lumia 2 smart earrings, has launched on Kickstarter with over 80 times the original goal of $10,000. The device was created in collaboration with researchers from Johns Hopkins, Duke and Harvard to assist patients with chronic blood flow disorders. It weighs less than 1 gram and is five times smaller than AirPods and can track over 20 health metrics, including sleep, activity (steps, calories, and active minutes), readiness, the menstrual cycle, temperature, heart rate and heart rate variability, blood oxygen (SpO2) and blood flow. The company claims that the device can collect continuous data, especially during the night, when most people charge their devices during this time. The accompanying app is compatible with an iPhone SE (second generation) or later, iOS 17 or later and Android 11 or later with Bluetooth Low Energy 5.0 or later. The data collected by Lumia 2 is encrypted, anonymized and access-controlled, and shares only with third-party cloud server providers such as AWS.
