While 4G technology made possible high-speed mobile browsing and wearable connectivity, 5G promises that those wearables will become even more prominent, smaller, and more efficient. That goes for ones already in existence, like smartwatches and health trackers, and those still on the drawing board (like, believe it or not, tattooables).
How that happens comes down to 5G’s accessibility to the cloud, its lower latency, and its speed, which can theoretically be 100 times faster than 4G.
Real-time data transfer will now be possible, and some experts believe that in the not-too-distant future, virtually everything we wear (clothing, shoes, contact lenses, even sensors placed under the skin to track health data) will transform us into walking, talking connected devices.
Certainly skeptics remain, but Fortune cites International Data Corporation projections indicating that wearable sales will reach $49.4 billion this year, and soar to $69.8 billion by 2024. Sanyogita Shamsunder, Verizon’s vice president of 5G Labs and Innovation, told Fortune that ‘2024 will in fact serve as an “inflection point,” as that will be the year that medical sensors will become commonplace.
Already available, Fortune notes, are smart glasses, smart earbuds (a.k.a. “hearables”) and yoga pants that make those wearing them aware if their yoga technique leaves something to be desired.
And those tattooables? While still in development, they are expected to be constructed of wafer-thin electric mesh, according to Fortune, which will enable them to store data and do things like deliver drugs.
The reason wearables are expected to shrink in size, according to TechRadar, is that they will no longer need physical space to store data; 5G can simply zip data right to the cloud. Instead, wearables of the near future will consist of ultrathin sensors, and little else.
An increase in sensors and a decrease in size is precisely what will cement wearables as part of the Internet of Things. Until now, we’ve mostly thought of wearables as items such as smartwatches that the user wears on their wrist. But these sensor-packed devices could just as easily be connected to objects rather than people to read and process data in real-time.
Consumers may also be happy to know that relieving some of the processor’s job means that a device’s battery will be more efficient. The ability to charge wirelessly within a wider range — up to 30 cm away — will allow devices to charge without cables or docks, even when in use.
All of this will take time, however. AT&T, Verizon and T-Mobile have all begun rolling out 5G, but it will be years before most of the country, let alone the world, has coverage. Then, manufacturers must create devices that harness the power of 5G.
In addition, there are privacy concerns about sensitive personal data being widely circulated, location data being easily accessible, and even foreign manufacturing threatening national security.
Such matters give one pause, to be sure. But for now, it’s full speed ahead for 5G, at 100 times the pace of the existing technology. While there are potential hurdles, there are also vast possibilities that make 5G’s future look extremely promising.
The problem with wearable sensors over the years has been one of durability. When repeatedly folded and bent, they developed micro-cracks that curtailed their conductivity.
Nothing a little red wine won’t fix. Or coffee. Or black tea.
The tannic acid present in those liquids was found by a team of scientists at the University of Manchester, England, to be crucial to improving the mechanical properties of wearables.
The team had previously used the same idea to develop artificial hands and capacitive breath sensors. Prior to the discovery of tannic acid as a useful tool in the creation of wearable technology, there had been many failures due to a lack of effective resources.
Tannic acid is the reason it is so difficult to remove red-wine stains from fabric: It firmly adheres to the material on the surface of the fiber. Such adhesion is, team leader Dr. Xuqing Liu, leader told Phys.org, “exactly what we need for durable, wearable, conductive devices.”
While scientists have been purchasing tannins to create these technological items, they tested fabrics by soaking them in coffee and black tea. They found that these liquids had the same effect on the fabrics that red wine did. This assured them that the adhesive properties of black coffee and tea are just as effective.
Using that knowledge, scientists are hopeful that in the near future they will be able to create wearable technology devices that are not only more comfortable but also longer-lasting and more cost-efficient.
Through the use of red wine, black tea and coffee, developers can create devices that, instead of being made of nylon, are made of cotton instead. The technology that is enabled by the use of tannic acid means that a device’s circuits will be attached to the surface of the fabric. This replaces the previous rigid circuit board with one that the wearer of the device isn’t even likely to notice.
While the technology industry is changing in many ways, wearable technology is among this and next year’s largest aspects. It has been predicted that sales of wearable technology around the world are set to reach a monetary value of $27 billion by 2022.
Yesterday’s wearable devices used conductive yarn. However, the coating on this material often peeled off, rendering it useless. Substituting tannic acid eliminates this problem.
Only time will tell what further research on this subject uncovers. But this latest breakthrough represents a quantum leap forward, in that it improves the durability of these widely used sensors. Moreover, it shows what can be accomplished through an outside-the-box approach — how a problem can be solved, if only it is approached from a different angle.
As personal health technologies such as wearable fitness and sleep trackers increase in popularity, we continue to see advancements in the convenient modern tech that allows us to monitor our health in increasingly complex and accurate ways. These steps forward leave us asking ourselves about the other ways we can use technology to improve our health. Recently, science has discovered that our intestines are much more important to our overall health than we previously thought, and as a result, we may just see gut trackers become the next big thing.
The importance of the gut stems from the enteric nervous system within our gastrointestinal tract. It is a lining made up of over 100 million nerve cells that span from the esophagus to the rectum that covers the entire gastrointestinal tract, and is commonly called our “second brain.” The gut has a direct relationship with the actual brain, and after sensing food or bacteria it will inform the nervous system, which relays this information to the brain and can affect behavior. Because of this connection, we are beginning to realize how we might treat particular disorders and conditions that may have links to the brain and to stress, such as obesity, anorexia, autism, and PTSD.
While our deeper understanding of the gut’s importance is still relatively fresh, the development of gut tracking technology has already begun to make headway, though most deal primarily with digestion. FoodMarble, a digestive health tech startup, is one of the first to produce a digestive tracker: a pocket-sized breath analysis device for users to track their digestion in real time.
When food isn’t quite fully digested, it ferments in the gut and produces hydrogen, most of which is exhaled naturally. FoodMarble users manually input what they’ve eaten and what relevant symptoms they are experiencing into an app, and the breath test is able to discern if the food has been fully digested. As you use the tracker more, the app will give you greater insights into how different types of foods, sleep quality, and stress levels affect their digestive health.
Other advancements in gut tracking are slightly trickier than a breath test. It’s hard to say what a “wearable” gut tracker would look like, but the closest thing to it is an ingestible tech pill developed by researchers at RMIT University in Australia. The pill closely tracks digestion through measuring the gases commonly found in the digestive system, such as hydrogen, oxygen and carbon dioxide.
Testing has already revealed new information to researchers. One such discovery is that the stomach releases oxidizing chemicals to break down foreign compounds that stay in the stomach longer than normal. The pill is a much less invasive option for monitoring gut health and human trials have been successful, so it may not be long before doctors are regularly using ingestible pills to help patients with gut problems.
Gut tracking options these days tend to have a purely digestive slant, but there remains great potential for gut trackers to dive into the gut-brain connection that is relevant to a multitude of issues. What if we had a gut tracker that could monitor the enteric nervous system and recognize when the synapses are being relayed from the brain and affecting the way the gut behaves? We are not quite there, but FoodMarble’s digestion tracker and the newly developed ingestible pill to track gut-gases are significant steps forward. Trackers that can monitor the gut-brain connection could very well be just around the corner.
2017 Agreement Between Players and NBA Says Practice Games Only
From Fitbit Trackers for the average consumer to the Zephyr Bioharness, which is allowed by Major League Baseball for players during actual games, wearable sports technology is hitting fields, tracks and gyms right and left. But not the basketball courts of the NBA, according to a recent decision between the organization and the Players Association.
The collective bargaining agreement released earlier this year states explicitly (and more than 250 pages into the document) that, “No Team may request a player to use any Wearable unless such device is one of the devices currently in use as set forth in Section 13(f)below or the device and the Team’s cybersecurity standards have been approved by the Committee.”
Section F makes it clear that players will only wear the device on a voluntary basis. The agreement further states that devices can be worn during practice— but not games.
Wearable devices for professional athletes measure everything from movement information (such as distance, velocity, acceleration, deceleration, jumps, and changes of direction), to biometric information (heart rate, heart rate variability, skin temperature, blood oxygen, hydration). Depending on the device, other health, fitness and performance information is gathered.
The technology is not, by today’s standard, new. The Adidas miCoach Elite Team System (one of approved devices for practice) hit the market in 2013. It’s touted, by Adidas, as the first of its kind “that uses physiological data in real time sending it straight to a coach’s tablet on the sideline. The system not only provides real-time insights during training, but tracks total training impact, collects and manages data and is highly portable.”
The goal of the system was to “offer insights into player performance and work rate, helping teams achieve and maintain peak physical performance.”
Apparently unconvinced about the need for wearable devices—but well aware that there’s no turning back from the wearable tech trend—the 2017 agreement sets up a committee to continue to explore the issue.
Wearable technology is far from limited to watches and glasses. Though smart clothing is admittedly taking longer to catch on, the possibilities are really endless when apparel is ascribed that “smart” quality that makes IoT products unique.
What if, for example, your pants were embedded with sensors that could tell you about your body, movements, and need throughout the day? Smart trousers are far from just a pipe dream. With various different visions in mind, several technology/apparel companies are developing pants that do more than just fit.
Sweetflexx, for example, sells leggings with “resistance band technology” to help wearers burn up to 255 extra calories a day, when worn. Their unique fabric technology is designed with comfort in mind, with crushed jade stone infused to lower body temperature by 10 degrees, and harness everyday movement to challenge muscles and tone your body.
Another type of smart athletic pants, developed by Athos, measures your muscular effort and maps it on a smartphone app. The app can tell you whether or not you are reaching your maximum muscle potential, if you are favoring one side of your body of another, or if some muscles are working harder than others.
There are also “smart tights” available for yoga enthusiasts. Sydney-based Nadi X comes with an app, and areas of the tights vibrate where posture and form need to be adjusted.
But as we’re discovering more and more, wearables have application outside of just sports. As one example, wearable tech trousers for tradesmen have been designed to keep workers safe. Developed by Snickers — the workwear company, not the candy — the pants house a device that collects data to alert wearers about knee protection and loud noise levels. The idea is to improve the health and safety of the employees wearing them, who may not realize when their health or safety is threatened. The data collection element of these wearables can help employers make adjustments that ensure safer, healthier conditions for workers.
Does wearing smart pants, necessarily, make you a smarty-pants? Maybe! The whole point of wearable technology is to add value and function, and it follows that the more value an item of clothing has, the smarter an investment it is. Though the examples listed probably aren’t for everybody, they do a great job of demonstrating that wearable technology has potential beyond wristwear.
