Developed by Korean tech startup Innomdle Lab, Sgnl comes in the form of a watch strap or a wristband. Once paired with a phone, the device can answer calls when a user touches their ear with a finger. The vibrations from the strap then travel up your wrist and into your fingertip which propagates the sound waves to your ear.
