Blockchain, once associated solely with the cryptocurrency bitcoin, has since been found to have many uses, with the potential for many more.
One of the foremost examples of digital ledger technology (DLT), blockchain can solidify supply chains and secure elections. It can make real estate transactions easier, and medical records more accessible. It can facilitate data transfers and ensure the smooth operation of the Internet of Things.
But why? What makes it so good, and why is there the expectation that it could do so much more?
In a word, security. The folks at MIT spelled it out in layman’s terms, while using bitcoin, widely considered the first digital currency, as an example. All of bitcoin’s transactions are stored in the ledger, with multiple copies shared to a network of computers, or nodes. These nodes, which are operated by so-called miners, determine the validity of every new transaction. In the case of bitcoin, for instance, they check to see that each miner seeking to complete a transaction using that particular crypto does in fact have one to spend. Valid transactions are then added to the chain as blocks.
Every block has its own cryptographic fingerprint (called a hash), and every completed transaction does so courtesy of a unique process known as a consensus protocol — i.e., the agreement between all the other nodes. Both those elements should at least theoretically make such transactions tamperproof.
The MIT crew does raise questions about how secure the network really is, and provides examples of instances when hot wallets or smart contracts, two DLT staples, have been hacked. But generally blockchain, and DLT in general, has been well-received.
Consider the following examples:
- Supply chain management: Using an online ledger removes documents, and thus inefficiency, from the equation. Consider the example of the shipment of flowers from Kenya to Rotterdam that required no fewer than 200 documents to complete. That’s a thing of the past with blockchain.
- Secure elections: It could potentially reduce fraud or, for that matter, the need to so much as travel to a polling place. In 2016 West Virginia became the first state to use DLT-based technology in a primary, a possible sign of things to come.
- Real estate transactions: With supply chains, there’s no need for hard copies anymore. All of that now exists in the blockchain network, and all parties have secure access. This is true for real estate transactions, and all manner of other transactions.
- Medical records: Electronic medical records (EMRs) are already widely used, but those stored in a blockchain would ensure the patient easier access and greater privacy, the latter of which is essential under HIPAA requirements.
- Data transfers: The cryptocurrency IOTA, believing most corporate data goes unused, has developed a DLT-based data marketplace that would allow companies to sell or share data, the idea being that it would spark innovation.
- IoT management: The world of interconnected devices — smart thermostats, lights, refrigerators, security systems, et al. — is ever-evolving, and in 2017 Cisco Systems moved to trademark a blockchain that would monitor the various devices for trustworthiness.
Clearly there is more to come. Blockchain will disrupt a great many sectors in the years to come, and we have its reliability and security to thank.
Even with layers upon layers of thick clothing, there is only so much regular fabrics can do to fight the cold. So how can we make our clothes do more to keep us warm? While it may seem like a less obvious avenue for technological advancement, the use of lightweight and conductive fibers to create smart thermal clothing have the potential to create new breakthroughs for insulation. We are already seeing promising advancements in smart thermal clothing, and it has the potential to much more effectively protect people from cold and even detect the onset of cold-related conditions, such as hypothermia or frostbite.
Smart thermal clothing entered the tech landscape years ago, but many of the developed incarnations at the time were bulky and inefficient, using invasive and uncomfortable wires or large batteries. For smart thermal clothing, the ultimate goal is to be completely unobstructive, regulating a person’s temperature with little to no inconvenience. As we continue to make advancements in specific lightweight fibers, such as ones made with graphene, we are beginning to see truly viable forms of smart thermal clothing.
SKIINCore is one such clothing range that boasts effective smart thermal clothing. Their products, which include a thin long-sleeve top and leggings, utilize a conductive yarn that is sandwiched between a sweat-wicking synthetic inner layer and a heat-trapping wool outer layer. It uses a small non-intrusive 56g battery for heating power, able to keep the wearer warm for up to eight hours. Users can adjust temperatures with a smartphone app, or let the “smart” in smart thermal clothing shine by allowing the clothes to automatically adjust heat levels based on environment and body temperatures.
Another example of exemplary smart thermal clothing comes from Directa Plus, an Italian company that makes graphene-based products. They recently launched two textile collections utilizing their Graphene Plus (G+) material, made from a patented Pristine Graphene Nanoplatelet design. Their G+ membranes can be applied to a flexible range of clothing, including sportswear, citywear or workwear. The use of graphene-based materials increase heat conductivity and spreads the heat evenly throughout the material to regulate overall body temperature. The G+ membrane also amplifies electrical conductivity, allowing for accurate transmission of data from the body.
With such advancements in smart thermal clothing, and smart clothes in general becoming an increasingly popular trend, the future for these heat-regulating garments looks bright. Already we are seeing effective smart thermal clothing options for mainstream consumers. But the utilization of lightweight fibers like graphene and other inconspicuous conductive materials in clothing still have much room for growth, and it seems that very soon in the future we will see smart thermal clothing become truly intelligent.
The quest to crack the machine learning code has been a dream of scientists since the invention of the computer. In 1950 the Turing Test captivated the public’s imagination with a question that likely seemed more based in science fiction than reality: could a computer ever match human intelligence?
We’ve come a long way since the technology of the 1950s, but the goal for machine learning is essentially the same. And we are living into the age when machine learning is bringing the kind of solutions to life that have previously been relegated to sci-fi.
Computers that can learn and adapt autonomously have fast become the new gold standard. And the startups leading the way into our AI future are answering questions even more interesting than whether androids dream of electric sheep. One of the most exciting industries ripe for an AI makeover is healthcare. Machine learning has the power to revolutionize how we detect and treat illness, and also how we approach patient care. Here are 5 machine learning startups in the healthcare sector to keep on your radar:
1. ID Avatars
ID Avatars recently raised $1M in funding to create emotional intelligence aimed at improving patient care for people with chronic diseases. By using avatars to interact with patients directly, this startup hopes to lead the charge in creating technology capable of providing empathy. This would have a huge ripple effect across the healthcare industry and would be as useful to hospitals and pharmaceutical companies as to patients.
The mission of Arterys is to make clinical care data driven with a machine-learning based imaging platform. They have developed the first 4D Flow Technology to measure blood flow more accurately and in a non-invasive way than current methods. The blood flow work can be done with any MRI. The tech is integrated with a SaaS platform for doctors to better interpret data on the go, and the potential applications for non-invasive blood analytics span across all kinds of medical needs.
London-based startup Babylon has raised more than $30M, and it’s easy to see why because their idea is so simple but brilliant: remote app-based medical care. In other words, Babylon is your virtual doctor, nurse and pharmacy in one. Imagine how much more streamlined emergency and on-demand care could be through app-based consultations. It’s already the highest rated service in UK healthcare and aims to expand to areas where healthcare is even more essential, like rural Africa, where doctors are scarce but cell phones are becoming commonplace.
Utilizing machine learning to create custom diet plans, Nuritas will be a game-changer in preventative health and overall wellness. Based on AI plus DNA analysis, Nuritas is designed to identify the healthiest ingredients specific to your dietary needs. The future will be full of bioactive peptides.
Developed by MIT scientists, Ginger.io uses predictive models to create a mental healthcare platform. This is a useful alternative model to traditional mental health care, which can be prohibitively expensive and frankly not that convenient for the modern world. App users can arrange a video call with a therapist, text with a health coach, learn coping strategies, and analyze their mood over time with the help of embedded sensors. This is mental health care for the 21st century.
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.
