Top Inventions of 2015

There’s no doubt that 2015 was a year of progress and innovation in technology. From health to safety to luxury, big ideas are changing our status quo. Here are some new inventions that I’ll be keeping an eye on in the coming year.

Nima by 6SensorLabs

A large percentage of the population suffers from celiac disease and gluten sensitivity, which can make eating at restaurants and parties risky business. Even traces of gluten protein can be dangerous. That’s why 6SensorLabs has developed a sensor to test food and drink samples for gluten. Users deposit a sample into the sensor’s well, where a proprietary antibody processes it for traces. If the sample is safe, a smile appears. If it contains gluten, a frown. This invention will make socializing a safe and anxiety-free experience for those with dietary needs.

Safety Truck by Samsung and Leo Burnett

The problem: staggering deaths in Argentina caused by trucks obstructing drivers’ views along windy roads. The solution: Samsung partnered with an ad agency to develop a system of four screens positioned on the back of a truck, which display footage taken from the front of the truck. So far, the technology has tested effective. With further refinement, road safety in Argentina will be vastly improved.

Casper Mattress

Mattress shopping is stressful. There are endless options, an array of features to choose from, prices to consider, and delivery to manage. But the Casper brand has an answer. The Casper mattress is a single style, made with a mix of comfortable foams, set at transparent prices, and sold exclusively online. It arrives in a vacuum-packed cardboard box. Not the best sleep of your life? Return it for a full refund within 100 days. No surprise why this one makes TIME’s best inventions of 2015.

Can you imagine what creations 2016 will bring us?
