10 of the Coolest Gadgets We Saw at CES 2018

Each January, tech companies from around the world gather in Las Vegas to show off their latest efforts at CES, formerly called the Consumer Electronics Show, the biggest gadget show of the year. While the products and demos showcased at CES don't always reflect the technology you'll be able to buy in the near future, the show does offer some insight into where tech giants are putting their time and resources. This year was all about improving communication between smart home gadgets, making the car feel more personal, and putting screens everywhere imaginable. Here's a look at some of the coolest products we came across on the CES showroom floor. L'Oréal's UV Sense is a tiny sensor capable of detecting ultraviolet exposure that's small enough to wear comfortably on your fingernail. The sensor itself is battery-free and includes an NFC antenna, a temperature sensor, and a UV sensor.
