Meet the Ear-O-Smart: a smart earring that monitors your heart rate, activity level, and calories burned to keep you on track. It connects to your smartphone and allows you to monitor your activity on the go. The device relies on the PPG technology to monitor pulse through blood flow in the skin. It has a battery that is good for 8+ hours. There is a custom kit available for folks who want to customize their earring.
This smart earring gives you yet another way to measure your heart rate on the go. The Learner’s kit, which is available on Kickstarter, is particularly fascinating. If you like what you see, you may want to support the project here.
