CES 2023: Smartwatches Expand Health, Wellness Features



  • Citizen, Fossil, eBuyNow, and iTouch all announced new smartwatches at CES, with health and wellness taking center stage
  • Kids and senior smartwatch market to grow as Xplora enters the US market
  • Companies continue to wait for new sensors to monitor blood sugar and blood pressure

At the beginning of this month, companies from around the world gathered in Las Vegas to unveil their most exciting pieces of technology at CES 2023. Everything from laptops to cars to VR glasses was on display and our analysts were at the event tracking the latest and greatest launches from tech companies. One area that we paid particular attention to was smartwatches, which saw several big announcements at the event.

Xplora plans entry into US smartwatch market, announces plans for a senior watch

Xplora is already popular throughout Europe, offering a lineup of differentiated kids watches that appeal to children in the 4-11 age group. The company is hoping that its strong performance in Europe can be replicated in the US when it launches in retail channels there later this year. In the US, most brands currently only offer one kids watch, if any at all. Xplora offers the X6Play, which won a Best of Innovation Award at CES, which is more powerful and has more advanced features, and the XGO3, which is less powerful and less expensive. Xplora is likely to benefit from having more advanced devices for kids at the top of its target age range and simple devices for kids at the bottom of the range. Additionally, service plan prices start at only $9.99/month, a full $5/month cheaper than Verizon or T-Mobile when pre-paying for a year of service, which will appeal to price-savvy consumers. Xplora also announced during CES that it was releasing a watch targeted at seniors. While the US does have some senior watch models available, this market remains immature and underpenetrated. Xplora’s expertise in kids watches should help give it a leg-up on the competition and a head start in addressing this underserved market.



Citizen announces two new smartwatches, moves beyond health and wellness tracking

Japanese heritage watch maker Citizen announced two new smartwatches to replace its current lineup. The Citizen CZ Smart Casual and CZ Smart Sport both feature sleek displays and a wide array of changeable bands, but the true innovation comes in the form of new health and wellness features. While most smartwatches today feature things like sleep tracking, heart rate tracking and even blood oxygen content, the CZ Smart Casual and Smart Sport go beyond health and wellness tracking to health and wellness prediction and intervention. The CZ Smart YouQ App uses tests adapted from NASA’s research to create a profile of user awareness and focus throughout the day. Users can use these profiles to glean insights into moments of peak performance and plan their day accordingly. After the first week, the app can also make recommendations to improve focus and awareness during points in the day when the user is predicted to see a drop.

Fossil announces new hybrid smartwatch

Fossil announced a new smartwatch at CES, the Fossil Gen 6 Hybrid Wellness Edition. The major feature of this watch is its E Ink display that shows health and wellness data such as heart rate, blood oxygen content and steps all behind two mechanical arms for analog time-keeping. The E Ink display helps keep power consumption low, with the device’s battery life advertised at two weeks. This is Fossil’s second hybrid smartwatch, and the first to include such in-depth health and wellness features, a clear indication of how health and wellness have become the driving use for smartwatches.

eBuyNow announces four new smartwatches under Motorola name

eBuyNow, the company behind the original Moto Watch, announced at CES that it would launch four new smartwatches under the Motorola name in the coming year. The company focused heavily on the Moto Watch 100, which while not specifically for seniors, is marketed as being the cheapest smartwatch on the market that features fall detection, a key feature for senior watches. In addition to the Moto Watch 100, eBuyNow announced the Moto Watch 70, Moto Watch 150 and Moto Watch 200, all of which are priced below $200.

iTouch announces new smartwatch and fitness tracker in partnership with fitness icon Jillian Michaels

iTouch announced that it would be launching its new iTouch Air 4 in partnership with fitness icon Jillian Michaels. The company says the Air 4 features improvements in the accuracy of its fitness tracking while aiming to help users improve their health and well-being without breaking the bank. The devices are expected to launch in the spring of this year through iTouch’s website as well as retail channels in the US. The device will likely cost users around $100.

There are a few things that the smartwatch announcements at CES can tell us about the direction that the smartwatch market is heading in. First, it is clear that health and wellness are the primary use case of smartwatches in 2023. Brands are expanding their health and wellness offerings to devices that did not previously offer them, improving their health tracking features, and even moving beyond health tracking to predictions and suggestions. Second, smartwatches targeting kids and seniors are expanding to the open market. T-Mobile and Verizon have both offered kids and senior watches in the past, but eBuyNow (Motorola) and Xplora are adding competition in open channels. Xplora is especially well-placed to disrupt these underpenetrated markets with its aggressive service prices and the know-how it brings from its success in European markets. Lastly, breakthroughs still are yet to be made in blood sugar tracking and blood pressure monitoring. But these are certainly targets for many OEMs down the line. Both features would significantly improve the usefulness of smartwatches and improve demand.

A Quick Guide to Better CMM Maintenance




A coordinate-measuring machine, also known as a CMM, is a specialized piece of equipment common in high-precision manufacturing. It uses coordinate technology to measure and replicate the dimensions of particular objects.

CMMs are a lot more accurate than regular measurement gauges. This characteristic makes them the equipment of choice for quality assurance in certain industries, like aerospace, defense, and medical manufacturing.

Despite being a powerful piece of equipment and the most versatile measuring tool in the metrology industry, CMMs can also be quite delicate. They require the right environment and proper maintenance practices to maintain accuracy and reliability.

The Importance of Proper CMM Maintenance

It’s essential to clean and inspect each part of your machine to ensure it stays efficient and accurate. Preventative maintenance ensures that your CMM remains accurate and performs at its best. It also improves your machine’s longevity.


Without proper CMM maintenance, you could risk damaging your CMM. Repairs would involve operational delays and additional costs.

CMM Preventative Maintenance Tips

Preventative maintenance practices are ones your team could do by yourselves. It’s best to schedule regular maintenance checks for your CMM daily, weekly, monthly, or quarterly. These checks can alert you immediately to possible problems with your CMM.

Remove dust and dirt regularly

Clean and well-maintained air bearings ensure your CMM works as it should. These frictionless and stable bearings help ensure accuracy and efficiency. Dust and dirt can clog your machine’s air bearings, affecting its overall performance.

Aside from your machine’s air bearings, dust could also get into other surfaces and crevices. These tiny particles could affect your machine’s accuracy.

Handle Stylus Tips Properly

The stylus is the tip that makes contact with the object you want to measure with your CMM. Despite this significant role, the stylus can be fragile and require careful handling. Too much force could cause it to bend or break.

Clean your stylus with a cleaning agent and a lint-free cloth. Make sure to remove any residue from workplace materials.

Ensure Good Air Quality

Most CMMs use air bearings, and good air quality is essential to keep them running smoothly. Various air quality issues could affect machine performance and even burn out machine motors.

For air quality maintenance, ask and address the following questions:

  • Do the lines have condensation, oil, or other contaminants?
  • Is the airflow constant?
  • Are you using the proper pressure?

When To Call a Professional

Most preventative maintenance practices are simple enough to be performed internally. However, some issues require professional attention. You can also conduct regular professional maintenance checks to ensure you don’t miss anything.

Below are some procedures that require professional assistance. Many CMM suppliers also offer maintenance services alongside their machinery.

Conducting CMM Training

CMMs are highly specialized pieces of equipment. To handle them properly, your staff needs professional training.

Training courses allow you to get trained by CMM experts on the tools and knowledge necessary within your industry. Regular training sessions also help keep you updated on industry trends and standards.

Sensor Malfunctions

CMM sensors are critical to your machine’s speed and accuracy. They should be professionally inspected and calibrated annually.

Routine sensor maintenance can significantly improve the efficiency and accuracy of your machine. CMM sensors include the following:

  • Scanning probe
  • Single point laser
  • Line laser
  • Electronic touch trigger probe
  • Video camera

Faulty Bearings

Neglected air bearings could cause them to falter in their accuracy and stability. Properly maintained air bearings ensure a smooth, stable, and accurate measurement process.

A professional metrology company can thoroughly inspect your air bearings to prevent further machine damage.

A CMM is a significant investment for any business. Good maintenance practices help your machine last and perform at its best, thus making the most out of this investment.

Nintendo’s discounted Switch game vouchers are back



Nintendo’s Switch Online service has become a better deal over time, offering more perks than just the ability to play games online. On top of getting access to SNES and NES classics, and cloud save backups (for most games, save a couple dozen), Nintendo announced an even bigger perk yesterday: discounted game vouchers.

All subscribers can buy a two-pack of these vouchers for $99.98, and a huge range of first-party (in other words, typically discount-averse) Nintendo games are looped in. I encourage you to check out the full list, but some highlights include the brand-new Fire Emblem Engage, Kirby’s Return to Dream Land Deluxe, Bayonetta Origins: Cereza and the Lost Demon, Metroid Dread, Splatoon 3, The Legend of Zelda: Breath of the Wild, and Pokémon Scarlet and Violet. Important note: you both have to be a subscriber to buy and use these vouchers.

It’s great that this list is more expansive than Nintendo’s first swing at this deal in 2019. But this perk could actually turn Switch Online into a must-have service because it allows you to pre-purchase up to four sets of vouchers (totaling eight games), and keep them for 12 months from the date of purchase. With $20 in savings with each pair of vouchers, buying four bundles will save you up to $80, assuming that each title normally costs $59.99. If you buy a lot of games, this is a smart way to save a little bit of money on every forthcoming purchase.

I know what you might be thinking: “Can I use one on The Legend of Zelda: Tears of the Kingdom?” Nintendo has not currently listed the deliriously anticipated sequel to Breath of the Wild, which is set to release on May 12th, 2023. Polygon has reached out to Nintendo to see if it’ll eventually become eligible, but did not hear back in time for publication.


You can get a free seven-day trial for Switch Online here, and you can easily subscribe to the service directly from the Switch’s eShop (it costs $3.99 per month, $7.99 for three months, or $19.99 per year). However, you can purchase (or gift) a one-year subscription with a digital code via Best Buy for $19.99. With a family subscription that costs $34.99 per year, up to eight Switch accounts can reap the perks of Switch Online.

For players who want all the perks, access to Goldeneye 007 and other N64 and Sega Genesis games, and complimentary DLC for some Switch games like Mario Kart 8 Deluxe, you’ll need Nintendo’s Switch Online plus the Expansion Pack tier, which costs $49.99 per year for one account, or $79.99 per year for a family subscription.

Canadian discovery could help batteries last longer



A chance discovery in a Canadian laboratory could help extend the life of laptop, phone and electric car batteries.

According to scientists from Dalhousie University in Halifax, common adhesive tape in batteries may be the reason many devices lose some of their power while off or not being used, which is a phenomenon known as self-discharge.

“In our laboratory we do many highly complex experiments to improve batteries, but this time we discovered a very simple thing,” Michael Metzger, an assistant professor in Dalhousie University’s physics and atmospheric science department, said in a news release. “In commercial battery cells there is tape—like Scotch tape—that holds the electrodes together and there is a chemical decomposition of this tape, which creates a molecule that leads to the self-discharge.”

The solution is simple, too, Metzger says: replace the polyethylene terephthalate, or PET, plastic tape commonly used inside batteries with something more durable and stable.


“It’s a commercially relevant discovery,” Metzger said. “It’s a small thing but it can definitely help improve battery cells.”

Metzger and his team have been trying to understand why lithium-ion battery cells in inactive devices tend to lose some of their power and self-discharge, something that has long frustrated consumers and manufacturers alike.

“Every manufacturer of lithium-ion cells in the world wants to make self-discharge as small as possible,” Metzger told in a joint statement with graduate student Anu Adamson. “In every battery there is a small rate of self-discharge that slowly drains the battery. This is very inconvenient for users and a big headache for industry.”

The electrodes that power batteries are separated by an electrolyte solution that is usually a form of lithium. After exposing several battery cells to different temperatures, researchers were surprised to see that electrolyte solution had turned bright red when it normally should be clear, which was something they had never encountered. The discovery was made by Adamson and two other students.

Chemical analysis of the red electrolyte solution revealed that at higher temperatures, a new molecule had been created inside the battery through the decomposition of common PET adhesive tape, which is often used to hold components together inside batteries. Strong and lightweight, PET is also frequently used for plastic packaging, drink bottles, clothing fibres and more.

Researchers realized that the red molecule, dimethyl terephthalate, was acting as a redox shuttle, meaning that it can transport electrons between a battery’s positive and negative electrodes, creating self-discharge and depleting power even when a battery is not in use. Ideally, the shuttling of electrons within a battery should only happen when a device is on.

“It’s a very simple thing—it is in every plastic bottle and no one would have thought that this has such a huge impact on how the lithium-ion cells degrade,” Metzger said in the news release. “It’s something we never expected because no one looks at these inactive components, these tapes and plastic foils in the battery cell, but it really needs to be considered if you want to limit side-reactions in the battery cell.”

The findings are outlined in a pair of studies published on Jan. 20 and Jan. 23 in the peer-reviewed Journal of The Electrochemical Society. The researchers are now testing PET tape substitutes.

“Since the PET in the tape is the culprit that creates the redox shuttle, we need to replace it with a polymer that is more stable and does not decompose in the harsh chemistry of a lithium-ion battery,” Metzger and Adamson told “So far, the results look very promising, and we plan to publish a new research paper on improved polymers for lithium-ion battery tapes soon.”

According to the researchers, their work has been attracting interest from “some of the world’s largest computer hardware companies and electric vehicle manufacturers,” which are eager to reduce self-discharge and improve battery performance.

“We visited some of these companies and they are planning to implement more stable polymers in their battery cells,” Metzger said.

In the release, Metzger noted: “One of the engineers said, ‘I heard you guys found out something is wrong with PET tape.’ So, I explained to him that it’s causing this self-discharge and asked him, ‘What are you using in your cells?’ He said, ‘PET tape.'”
