Here is a smart gadget that lets you take phone calls by simply putting a finger to you ear. Sgnl doesn’t require you to carry an additional earpiece to listen to your calls. It replaces your existing watch strap, and you are set. The device is compatible with a wide variety of watches, including the Apple Watch and Pebble Time.
Sgnl generates vibration through its Body Conduction Unit and transmits it through your hand to your fingertip. Once you put your finger to your ear, you will be able to hear sound. Let’s not forget that your finger blocks out background noise as you take calls. This project is already killing it on Kickstarter.
