Lego's next release is a digital brick loaded with sensors that add new layers of interactivity to its play sets. WIRED got exclusive access to the Lego labs where the Smart Brick was born. The secretive division of 237 staff based here and in London, Boston, and Singapore is dedicated to thinking up what comes next for the world's largest toy brand. In front of me, on a plain white table, is a batch of prototypes of Lego's new Smart Brick, the final version of which is a small, sensor-laden 2-by-4 black brick with a big brain. No outsider has seen these prototypes, all of which represent stages of a journey Lego has been charting over the past eight years. Lego hopes this innovation, which lands in stores March 1, will safeguard the future of its plastic empire. The diminutive proportions of the finished Smart Brick belie the fact that the thing is exceedingly clever. Inside is a tiny custom chip running bespoke software that can communicate with onboard sensors to monitor and react to motion, orientation, and magnetic fields. It's also likely no exaggeration that the Smart Brick could represent the most radical product Lego has produced since Jens Nygaard Knudsen, the company's former longtime chief designer, created the minifigure nearly 50 years ago.

It's the first week of a new year and there's no time for the tech world to slowly ease back into things following the holidays. That's because CES 2026 is in full swing, with all manner of companies descending on Las Vegas to reveal their latest innovations and what they're planning to bring your way in the near future. Many of the Engadget crew are on the ground to check out as much of the new tech as possible. Samsung held its First Look presentation, which focuses on home products, while LG has shown off a wide array of TVs and Lego unveiled its new Smart Brick technology. We've heard from the major chipmakers, gone hands-on with Samsung's trifold phone, checked out some funky laptops and seen some cute robots. There's some hot gaming gear at the show too, not to mention some weird tech . You don't necessarily have to wait to get your hands on all of these gadgets either. Some are available to buy right now. You can catch up on all of the big CES 2026 announcements (and some of the more offbeat gizmos we've seen) right here. We'll be keeping this story updated throughout the week. We also have CES live updates, with all the latest news from the event. Lego introduced the Smart Brick at CES 2026. In its first CES appearance, Lego announced the Smart Brick, a standard-sized brick with a 4.1mm ASIC chip inside that's designed to respond in different ways depending on what set you're building and how you're building it. Using what Lego calls the "Play Engine" and integrated copper coils, each brick can sense things like motion, orientation and magnetic fields, plus its own distance, direction and orientation in relation to other Smart Bricks. Each brick also has a teeny tiny speaker built in that will play audio "tied to live play actions" rather than only pre-recorded clips. Accompanying Smart Bricks are Smart Tags and Smart Minifigures, which have their own capabilities -- one of which is letting Smart Bricks know what context they are being used in. All of these pieces tie together via a local wireless layer dubbed BrickNet that, in part, lets Smart Bricks know where they are placed in relation to other smart components.

Lego's Smart Brick Gives the Iconic Analog Toy a New Digital Brain The new sensor-packed Smart Play Brick will land this spring as part of a special Star Wars collection. The update adds interactive lights and sound to the Lego experience--including the minifigs. At CES in Las Vegas today, Lego has unveiled its new Smart Play platform, aimed at taking its distinctly analog plastic blocks and figures into a new world of tech-powered interactive play--but crucially one without any reliance on screens. Smart Play revolves around Lego's patented sensor-and tech-packed brick. It's the same size as a standard 2 x 4 Lego brick, but it is capable of connecting to compatible Smart Minifigures and Smart Tags and interacting with them in real time.
