Fingertip Acts as Phone with Sgnl Smart Strap

Sgnl is a new gadget on Kickstarter basically designed to make you feel like a secret agent. It lets you make phone calls just by wearing a wristband and touching your ear, with your fingers acting as the receiver.

There’s no speaker on the device — instead, audio is directed into your ear through vibrations that are sent through your body, into your wrist and up to the fingers touching your ear; a mic is built into the band. It’s not a new concept, but it’s a neat twist on the not-very-cool Bluetooth headset.

You can replace your existing watch strap with Sgnl, whether it is an analog wristwatch or a smart wristwatch.
