This smart pendant can save your skin from sunburn

Smartphones and smartwatches are cool and all, but can they tell you when you will get sunburn? This smart pendant can! Meet the Gem.

The Gem tracks your sun exposure

The Gem is a stylish-looking smart pendant that you can mistake for jewelry. It can do some really cool things for you, though. The gadget has an array of sensors inside its titanium chassis that can measure the amount of UVA and UVB radiation your skin is absorbing.

You can see your exposure in real time inside the companion app and customize it with things like skin type, your habits, whether or not you're wearing a sunscreen, what the level of protection is, etc.

It can prevent sunburn

Sunburn is a nasty thing. Not only is it annoying and itchy, but it can also increase your skin cancer risk. But it's also quite subjective.

The Gem can help with that as well. After you feed all the personal data inside the app, the Gem can give you an estimate of how long you can stay in the sun unprotected before your skin turns red and… you know the rest.

Plus, you can nerd out looking at those pretty UVA and UVB charts inside the app. The battery of the Gem lasts around one week on a single charge, takes just two hours to fill up, and the thing is also splash resistant.

Now for some bad news

This sensor on a chain is not cheap. You can get one at a promo price of $199 from The90's official website.

This promotion will last four weeks, after which the price jumps to $299 per unit. You can choose from two colors — gold and silver — which will pair well with most fashion styles and colors out there.

The price is a bit on the high side, given UV sensors can be bought for a few bucks. Granted, you're getting a fashion product and a companion app, but $300 is a bit much.

New medical niche for wearables?

What The Gem is doing right is probing this new niche. Of course, measuring UV exposure is nothing new; UV detection and exposure bracelets have been around for ages. But adding the pretty app with graphs and customization is a step in the right direction.

And getting FDA certification for things like risk of skin cancer based on exposure seems the way to go.

We have smartwatches that can take your blood pressure and even blood sugar now, so adding the sun exposure to the mix is quite cool. I would love to see a cheaper alternative, though.
