If you look beyond the shiny new cars, the walls of TVs and millions of wearables, you can see some strange things at CES. Not only are there floating ladies in pools, there are extracurricular activities that happen outside of the convention center floor. There are also a lot of off-the-wall products that will either make you excited or fearful for the future. We’ll let you be the judge. Here are five of the wackier gadgets we’ve seen this week.
Because walking takes too long
Have you ever been walking down the street and thought, “Gee, I wish I could get to my destination quicker.” Well, a French company called Rollkers thinks it has a solution.
Inspired by the moving walkways found in airports, Rollkers clip onto your shoe (much like the old roller skates) and use a small motor to help you walk twice as fast as your normal rate (up to seven miles per hour). According to Rollkers, there is no training needed. They’re “self-balancing,” so you just walk like you normally do.
While the version I saw at CES was really clunky and heavy, the company says the final product will be much lighter. They’re due out in early 2016 and will cost around $400. I’d love to see how this would fly on the crowded sidewalks of New York.
An Internet-connected aquarium for Nemo
In the second grade, I won a couple of goldfish at a school carnival. Excited to have my first pets, my parents helped me set up a small aquarium, and I named them Fred and Barney. The next day, they were dead.
FishBit is a product designed to help avoid such a massacre. It’s an Internet-connected monitor that you stick into your aquarium; it basically tells you about your aquarium’s water quality. Using various sensors, it sends data about the water’s pH levels, temperature and salinity to a mobile app on your phone (iOS only for now). It can also advise people on which fish to buy based on the size of their tank, water composition and the other types of fish they already have.
FishBit is currently raising funds via Kickstarter and has already met its goal. The company hopes to go into production by the end of the year. Pricing is still TBD, but the company said it will be less than competitive products.
Print me a cheese pizza, please
We’ve seen 3-D printers make some incredible things, but food has not been one of them — until now. At CES, Chinese company XYZPrinting showed off a 3-D Food Printer capable of making cookies, pastries and cake decorations.
Using three extruders, I watched the printer churn out intricate patterns made of chocolate paste. It can also use ingredients like jams and cookie dough, but note that you actually still have to do the baking. And while it’s limited to desserts for now, the company says the printer could eventually be used to make things like pizzas (yum?).
XYZPrinting plans to release the 3-D Food Printer for commercial use later this year, but a lower-cost, consumer version is also in the works.
The Hapifork for babies
A couple of CES-es ago, a product called the Hapifork caught the attention of many people. The electronic fork monitors how much you eat and how fast you eat to help curb overeating and digestion problems. Well, this year, the same company has come out with a similar product for babies called Baby Glgl.
This “smart” baby bottle is designed to prevent babies from gulping in too much air when they drink, which can lead to colic and indigestion. It has LED indicators that let you know if you need to adjust the angle of the bottle to reduce air bubbles. The Bluetooth-enabled bottle also connects to a mobile app so parents can track how much and how fast a baby is drinking. Baby Glgl will be available this year and cost around $100.
A Bluetooth fertility monitor that you insert you-know-where
A Boulder, Colo.-based startup called Prima-Temp has created a high-tech way for women to monitor when they’re most fertile. Called Bloom, the sensor continuously measures a woman’s core body temperature to detect changes that occur before ovulation, and then via Bluetooth, sends an alert to a companion smartphone app when she’s most fertile. It’s designed to be worn for about a month (similar to the NuvaRing birth control ring), and will cost about $150 per ring.
Bloom doesn’t require approval from the FDA, but it is FDA regulated, so it goes through the same testing, labeling requirements and so forth. Prima-Temp hopes to launch the product this summer.
