You may have heard of smartphones and even smart rings, but what about smart earrings? Today on the show, fashion tech journalist Amanda Cosco sits down with Ashlyn Bird, co-founder of Ear-O-Smart, the world’s first smart earring. While Ear-O-Smart may have started as a direct-to-consumer product, they’ve recently pivoted to focus on offering a universal backing that’s comparable with almost any pair of earrings. The backing reads bio-signals, such as hart rate, calories, and activity, and makes this information available via a companion app. Amanda and Ashlyn talk about why the ear is the best place to gather biometrics, and the challenges of shrinking down a sophisticated piece of hardware into something that fits discretely behind the ear.
