The hair accessory that could save your life

SEATTLE -- Plenty of wearables (wearable technology) can help you better your life by tracking your vital signs and activity.

The First Sign Smart Hair Clip is designed to safeguard your life.

It knows when you're pushed or thrown, when you're running, it also knows where your phone is at all times - even when you're nowhere near it. It automatically transmits all this information to a preset list of contacts or professional security monitor who will - in the case of an attack - not only track the activity in real-time but also contact the nearest authorities to send help to your location.

Bear in mind that this entire process happens in the 90 seconds after an attack.

As a girl who has carried pepper spray in the past (and who may or may not have accidentally set it off) I had a couple concerns:

    It's hard to see the downside of the First Sign hair clip - though given that it won't come out until this fall widespread user experiences aren't available yet. But at $50 (the device without monitoring subscription) or $75 (1 year monthly monitoring included) this could make for a great grad or birthday present.

    I know I'd feel safer.
