Top Insane Crazy Gadgets We Loved in 2017

5. Amabrush

Called the “world’s first automatic toothbrush”, it’s a vibrating toothbrush capable of vigorously and efficiently cleaning your teeth in just 10 seconds with its automated system. By our estimates, even using the Amabrush twice a day instead of a regular toothbrush can cut the time spent brushing your teeth by a factor of three. That’s a lot of time saved for a relaxed morning chai or coffee.

6. Smart underwear to ease your back pain

A research team at the Vanderbilt University combined biomechanics with wearable technology to create a smart, mechanized undergarment that can alleviate your back pain. It’s basically two fabric sections (one for the chest and one for the legs) fastened together by tough straps. A double tap on the chest’s sensor tightens everything so you can lift a heavy weight without stressing your back, while double tapping again lets it behave like regular comfortable clothing once more. Most importantly, it’s also designed to be unobtrusive under your clothes.
