Wearable technology is often touted as one of the greatest applications of the Internet of Things, and with good reason. Wearable electronics that consumers can display on their bodies have the potential to transform the way we live. Devices from Fitbit and its peer companies allow people to track their health and exercise progress in previously impossible ways. And smartwatches bring the power of smartphones directly to the wearer’s wrist. But IoT devices didn’t just crop up out of nowhere. This wearable technology can trace its roots back further than you might think, and the road ahead for wearable devices looks bright.
