Every year, TIME highlights inventions that are making the world better, smarter and a bit more fun. (See last year’s list here.)
To assemble our list of 2021’s Best Inventions, we solicited nominations across a variety of categories from TIME’s editors and correspondents around the world, and through an online application process. We then evaluated each contender on a number of key factors, including originality, creativity, efficacy, ambition and impact.
