They are hailed as the gadgets that will revolutionise our lives – or those of our pets.
But just how many of us will consider these hi-tech innovations as must-haves is open to question.
They range from a toothbrush that can clean your teeth in ten seconds to a feeding bowl that can recognise your cat and send pictures of it eating.
Other gadgets on show this week at the annual Consumer Electronics Show in Las Vegas include ‘walking’ emergency vehicles that could be deployed in rough terrain in areas devastated by earthquake or flood.
Then there is a hand-held wand that takes close-up pictures of the face and applies tiny amounts of make-up serum to cover any imperfections such as broken veins or age spots.
And, in a sign of the times, there are even sex toys that link to your Amazon Alexa or Apple Watch devices.
This cleans your teeth in just ten seconds. The battery operated tray comes in four different sizes.
It fits over the teeth and, as it vibrates, fine nylon bristles clean them, using normal toothpaste.
After five seconds on the top, the tray is flipped over for five seconds on the bottom.
For the best results, users should make a chewing motion.
The Wall Micro LED
Samsung revealed its latest Micro LED displays, which can be arranged in almost any configuration to fit a given room, no matter its shape or size.
The firm held a first-look event at CES to show off the technology, which it used to build a new 75-inch design and a 219-inch version of The Wall.
Samsung first introduced Micro LED last year, and has since improved the technology to allow for displays small enough to fit in the home.
The company’s Micro LED displays rely on millions of tiny self-emissive modules, which give off red, green, and blue light to combine for stunningly sharp colors.
The firm took The Wall up a notch this year, boosting it from the 146-inch display debuted last year to a whopping 219 inches.
Since the entire system is modular, users can customize their own display to fit the space perfectly.
This includes even irregular screen sizes, such as 9×3, 1×7 or 5×1, the firm says.
And, the picture quality remains just as crisp no matter the configuration.
Dreamlight (£40 to £235)
With orange lights to ease you to sleep and green to wake you up, this eye mask and headband claims to be able to send insomniacs into a deep slumber. It feeds data to an app, telling users how much sleep they have had. The mask claims to ease jet lag and remove puffiness.
There is also a ‘heating mask’ which is meant to simulate a person stroking your face.
The Dreamlight is a heavily padded and contoured strip that wraps around your head and attaches with velcro.
Urgonight, a sleep-tracking headset by French startup Urgo Group trains your brain to sleep better.
The headband connects to the Urgonight app and trains your brain into developing wave patterns for healthier sleep.
The Urgonight EEG (electroencephalogram) therapy requires three 20-minute sessions per week, which then gives you feedback in the app that shows your session progress in real time.
The team say that sustainable results take three months to achieve but that it helps you learn how to produce brainwaves that enhance your natural sleep.
A portable dishwasher the size of a cardboard box and weight of a small suitcase, it washes the dishes using just four litres of water. With its own reservoir, it can be used anywhere that has an electrical socket.
It may look similar to a large coffee machine but this is a home beer maker. It brews ten pints in a fortnight using three espresso pod-style capsules that contain the malt, flavouring and hop oil. It can make pale ale, stout or lager and is self-cleaning. The price and release date have not been announced.
The Mookkie (£150)
This smart feeding bowl uses facial recognition to unlock access for your cat, preventing a rival from stealing their food while keeping out flies. Its wifi link allows the owner to watch via phone as their pet tucks in.
The Consumer Electronics Show is an annual technology convention that takes place in Las Vegas.
The show typically takes place in early January.
It attracts hundreds of thousands of attendees from all over the world, as well as thousands of tech firms, startups and entrepreneurs.
Companies show off their latest innovations, ranging from the latest robots, autonomous vehicles and smart assistant-equipped gadgets.
Numi 2.0 Intelligent Toilet
Plumbing company Kohler showed off an ‘intelligent toilet’ with built-in surround sound speakers, ambient mood lighting, and Amazon Alexa voice controls.
The Numi 2.0 Intelligent Toilet also has personalised cleansing and drier functions, and comes with a promise of ‘exceptional water efficiency’.
‘Connected technology is driving innovation in the smart home category, but connectivity alone isn’t enough,’ said David Kohler, Kohler’s chief.
‘We believe in leading with design and seamlessly incorporating the right technologies so that our customers can personalise their bathroom experiences to be just right for them.’
The Breadbot — a carb vending machine – was another highlight of the show.
The automated device starts with dry ingredients and bakes several types of bread, including white, whole wheat, nine grain, sourdough and honey oat.
The bread requires fewer preservatives since it’s made on the spot, The Wilkinson Baking Company says.
Three US grocery chains will begin testing it out in stores later this year, though Breadbot’s makers would not specify which ones.
