Forget batteries, this powered toothbrush runs solely on kinetic energy

Add as a preferred source on Google

Next to our smartphones, electric toothbrushes are among the best gadgets in our lives, guaranteeing a hygienist-approved tooth clean at the start and end of each day. The one time we hate our electric toothbrushes? When we forget to charge the battery, and they whir to a sad halt mid-brush. That is a problem that a new Kickstarter campaign promises to bring an end to — courtesy of a “hybrid toothbrush” which promises the power and performance of an electric toothbrush, without any need for batteries or electricity.

Claiming to be the first brush of its kind, the Be. toothbrush operates on a principle not entirely unlike a watch movement mechanism, reappropriated to deliver a higher torque in a shorter time span. Using a series of power springs, dampers, gear boxes, and other components, its makers boast that it can give you an electric toothbrush-level clean in exchange for you giving it a few brief twists before you use it — much like winding a watch.

“There are 1,440 minutes in a day, and the average person uses four of the minutes a day to brush their teeth,” Patrick Triato, CEO of manufacturer Goodwell Company, told Digital Trends. “That means that for 99.73 percent of every day, your toothbrush is just sitting there, and if it’s an electric toothbrush it’s either trickle charging or slowly draining a disposable battery. We believe that some things just don’t need batteries, especially things that go unused for 99.73 percent of the time. The Be. brush is pioneering a whole new category of toothbrush that does not use batteries, cables, chargers or electricity, yet gives you the diamond clean of a powered toothbrush. Why is this exciting? From situations like disaster relief to military use to your weekend backpack trip, having a brush that doesn’t need the grid to give you a better clean is something we believe is going to change the landscape.”

Provided it works as well as its creator suggests, this could be a “must-have” product. If you want to get hold of a Be. toothbrush of your own, you can pre-order one on Kickstarter, where prices start at $49, complete with replacement heads, travel case, and more. Shipping is set to take place in December 2018.

Apple appears to be preparing a much broader push into smart-home hardware, with several new products in development as the company looks to expand beyond the HomePod mini and Apple TV, according to a 9To5Mac report.

The roadmap includes refreshed versions of both existing products, a new smart-home hub with a display, a larger HomePod update, and eventually Apple's first dedicated smart-home security devices. The information comes from recent reporting summarized by 9to5Mac, which notes that Siri's long-awaited AI upgrades could remove one of the obstacles that has held back new Home products.

Lutron just made it easier to control your smart home without touching your phone
Smart home voice control usually means buying yet another speaker or hub. Lutron and Sonos found a simpler fix: use the speaker you probably already own.
Electronics, Speaker, Text

If you’ve lost count of how many remotes and apps you juggle between just to dim a light or skip a song, I have something for you. Lutron just gave its Caseta smart home lineup a new shortcut, letting you control lights, shades, and Sonos playback with your voice alone.

For anyone who is catching up, Caseta is Lutron's do-it-yourself smart lighting system. It’s built around a small hub that basically talks to switches, dimmers, and plugs over a radio signal (instead of Wi-Fi), making it easier to manage the entire setup. While the company has worked alongside Sonos for a while, voice control was the one piece still missing from that partnership. That changes now.

The best smart home gym equipment
Find the connected fitness equipment that's worth your money.

The average workout doesn't begin with your first rep anymore. It begins with the data you've already collected. Smartwatches track your sleep and heart rate, smart rings measure recovery, and some fitness enthusiasts even use continuous glucose monitors to better understand how their bodies respond to training and nutrition. Smart home gym equipment builds on that foundation, combining connected hardware with AI-powered coaching, adaptive resistance, and long-term progress tracking to turn health insights into smarter workouts.

Smart fitness has also grown well beyond streaming workout classes. The latest machines can automatically adjust resistance as you get stronger, analyze your performance over time, and sync with the health devices you already use. Some even use AI to recommend workouts based on your goals and training history, making every session feel more personalized. If you're still deciding whether investing in connected fitness makes sense for your lifestyle, check out our guide on whether a smart home gym is worth it.
