Health And Fitness Trackers Are Becoming A Lot More Granular

From counting 10,000 steps to reminding when to stand or take a few deep breaths, many Americans have become accustomed to devices quantifying their progress toward health goals. Is this just the beginning?

Businesses and researchers are dreaming up the next generation of methods to create and quantify personal data, with the aim of using the information to boost health and happiness. Some technologies are in their infancy, including machines that sit in the home, passively scanning for early signs of illness. Others are in limited use. Still others, such as smart thermometers and blood-glucose monitors, are widespread, but their proponents see untapped potential in the data they collect.

These advances bring concerns about security, as sensitive information is beamed up to the cloud, and privacy, especially in cases where manufacturers own data about their customers’ health that the customers themselves can’t access. It’s still too early to know exactly which metrics correspond to improved health, or whether zealously tracking them itself has negative impacts.

Natural Medicine

Research has shown that time outdoors can benefit well-being—but do certain natural settings have an outsize effect? NatureQuant, based in Bend, Ore., is aiming to quantify time in nature. This week, the company released NatureDose, an app that tracks people’s time indoors and outdoors as they go about their daily routines. The app can map the types of nature a person passes, whether a lake or tree-lined city street, through phone sensors including GPS and accelerometers. That data is paired with NatureQuant’s mapping systems to determine a person’s proximity to natural elements. The app is being tested in clinical trials in universities, with the aim of determining how time in nature impacts anxiety and depression. Eventually, the company hopes, health professionals could use the data to prescribe time in nature, even tailoring recommendations by lifestyle, season and locale. For example, the app could alert users with vitamin D deficiencies to the best time to catch UV rays.

Watch Your Mouth

Dentists have long advised brushing teeth for two minutes twice a day. In the future, quantifying dental data, such as tracking acidity in the mouth, may help forecast cavities before they happen and draw connections between oral health and other health issues. For example, night guards or other devices that measure specific biomarkers in saliva could uncover disease, such as inflammation of the gums that is linked to diabetes, says Dr. Corneliu Sima, an assistant professor of oral medicine, infection and immunity at the Harvard School of Dental Medicine. Camera-enabled toothbrushes could serve as oral scanners, beaming real-time information to dentists, who could use machine learning to sift through the data to determine whether patients need to come in for a visit, he says.

Body of Water

The well-known admonition to drink eight glasses of water a day has persuaded many Americans to lug around water bottles in the hopes of satisfying their hydration needs. Hydration, after all, has been shown to benefit brain function, heart health, digestion and other bodily functions. Is eight glasses really the right number for everybody? In the future, connected devices could help assess how much water is the optimum amount for each individual. The PÜL SmartCap, a mobile-connected water-bottle cap, recently hit the market promising to help consumers set goals and track their hydration levels with an accompanying app.

In the Blood

Some people are wearing blood-glucose monitoring devices, which continuously measure blood sugar via a small device worn on the arm, even if they don’t have diabetes. Elevated or spiking blood sugar is linked to heart disease, stroke and diabetes, so proponents of blood-glucose monitors say that tracking blood sugar could help wearers personalize their diets and live healthier lives. The Levels software, for example, allows users to watch their glucose levels on an app as they eat different foods, exercise and sleep. Ultimately, the company envisions people having several biosensor streams to help them optimize cell function and predict disease, says Dr. Casey Means, the chief medical officer of Levels.

The Wearable You Don’t Need to Wear

Researchers at the Massachusetts Institute of Technology have created a wall-mounted, laptop-size box that sits in the home, analyzing electromagnetic waves around residents as a noninvasive way of gauging health metrics. Using machine learning, the device can track breathing, heart rate, movement, gait, time in bed and the length and quality of sleep—even through walls. Health organizations, hospitals and medical schools are using the device. It is being used in clinical studies for Parkinson’s disease, Alzheimer’s and immune diseases and was used to monitor Covid-19 patients in isolation during the first wave of the pandemic. Dr. Dina Katabi, a professor at MIT’s computer science and artificial intelligence lab who led the project, says the boxes could be used in the homes of seniors and others to help detect early signs of serious medical conditions, and as an alternative to wearables.

Taking the Temperature

Thermometers are ubiquitous in households across the country. They are often the first medical tool that people consult once they start feeling sick. Aggregating those temperature readings and associated symptoms could someday quantify and diagnose illness at a population level. In the coming years, smart thermometers may be able to help determine whether patients have particular strains of flu or Covid-19, based on symptoms, temperature and other data collected in the area. Inder Singh, the founder of Kinsa, a San Francisco-based smart-thermometer company, says this kind of diagnosis could allow patients to bypass doctor visits and get medication quickly. Kinsa is working to turn its smart thermometers, introduced in 2013, into a system that detects outbreaks and tells people how and when they should seek treatment. The network has about 2.5 million thermometers in the U.S. so far.

Old Dog, New Tricks

Pet owners, including the many who adopted animals during the pandemic, are seeking to quantify the health of their furry friends as well. Whistle Fit, for example, offers a glimpse into a possible future for connected pet care. The 1.5-inch device affixes to a dog’s or cat’s collar and monitors its health, fitness and behaviour. Sensors collect data about a pet’s daily routine. Algorithms analyze the data to detect behavior tied to well-being, including playing, running, sleeping, exercising and drinking. After establishing a baseline, Whistle can determine whether a pet’s behaviour is changing. The owner can set exercise goals based on breed, age and weight. The company provides summaries to share with vets and alerts around behavioural problems like excessive licking or scratching.

The Right Amount of ZZZs

A plethora of products is already on the market to help people sleep. More futuristic offerings include robots that help lull patients to sleep with breathing exercises and “digital sleeping pills,” beamed through headbands that play music or soothing sounds when they sense users are about to wake up, says Dr. Seema Khosla, the medical director at the North Dakota Center for Sleep. Going forward, it would be helpful to have a bespoke assessment of how much sleep each individual needs, as opposed to the one-size-fits-all recommendation of eight hours, she says. Devices will likely be less clunky in the coming years, she says, sitting by the bedside with less need for physical contact with the sleeper.

The marketplace has spoken and, at least for now, it’s showing preference for hybrids and plug-in hybrids (PHEVs) over battery electrics. That makes Toyota’s foot dragging on EVs (and full speed ahead on hybrids) look fairly wise, though the timeline along a bumpy road still gets us to full electrification by 2035.

Italian supercar producer Lamborghini, in business since 1963, is also proceeding, incrementally, toward battery power. In an interview, Federico Foschini , Lamborghini’s chief global marketing and sales officer, talked about the new Urus SE plug-in hybrid the company showed at its lounge in New York on Monday.

The Urus SE SUV will sell for US$258,000 in the U.S. (the company’s biggest market) when it goes on sale internationally in the first quarter of 2025, Foschini says.

“We’re using the contribution from the electric motor and battery to not only lower emissions but also to boost performance,” he says. “Next year, all three of our models [the others are the Revuelto, a PHEV from launch, and the continuation of the Huracán] will be available as PHEVs.”

The Euro-spec Urus SE will have a stated 37 miles of electric-only range, thanks to a 192-horsepower electric motor and a 25.9-kilowatt-hour battery, but that distance will probably be less in stricter U.S. federal testing. In electric mode, the SE can reach 81 miles per hour. With the 4-litre 620-horsepower twin-turbo V8 engine engaged, the picture is quite different. With 789 horsepower and 701 pound-feet of torque on tap, the SE—as big as it is—can reach 62 mph in 3.4 seconds and attain 193 mph. It’s marginally faster than the Urus S, but also slightly under the cutting-edge Urus Performante model. Lamborghini says the SE reduces emissions by 80% compared to a standard Urus.

Lamborghini’s Urus plans are a little complicated. The company’s order books are full through 2025, but after that it plans to ditch the S and Performante models and produce only the SE. That’s only for a year, however, because the all-electric Urus should arrive by 2029.

Thanks to the electric motor, the Urus SE offers all-wheel drive. The motor is situated inside the eight-speed automatic transmission, and it acts as a booster for the V8 but it can also drive the wheels on its own. The electric torque-vectoring system distributes power to the wheels that need it for improved cornering. The Urus SE has six driving modes, with variations that give a total of 11 performance options. There are carbon ceramic brakes front and rear.

To distinguish it, the Urus SE gets a new “floating” hood design and a new grille, headlights with matrix LED technology and a new lighting signature, and a redesigned bumper. There are more than 100 bodywork styling options, and 47 interior color combinations, with four embroidery types. The rear liftgate has also been restyled, with lights that connect the tail light clusters. The rear diffuser was redesigned to give 35% more downforce (compared to the Urus S) and keep the car on the road.

The Urus represents about 60% of U.S. Lamborghini sales, Foschini says, and in the early years 80% of buyers were new to the brand. Now it’s down to 70%because, as Foschini says, some happy Urus owners have upgraded to the Performante model. Lamborghini sold 3,000 cars last year in the U.S., where it has 44 dealers. Global sales were 10,112, the first time the marque went into five figures.

The average Urus buyer is 45 years old, though it’s 10 years younger in China and 10 years older in Japan. Only 10% are women, though that percentage is increasing.

“The customer base is widening, thanks to the broad appeal of the Urus—it’s a very usable car,” Foschini says. “The new buyers are successful in business, appreciate the technology, the performance, the unconventional design, and the fun-to-drive nature of the Urus.”

Maserati has two SUVs in its lineup, the Levante and the smaller Grecale. But Foschini says Lamborghini has no such plans. “A smaller SUV is not consistent with the positioning of our brand,” he says. “It’s not what we need in our portfolio now.”

It’s unclear exactly when Lamborghini will become an all-battery-electric brand. Foschini says that the Italian automaker is working with Volkswagen Group partner Porsche on e-fuel, synthetic and renewably made gasoline that could presumably extend the brand’s internal-combustion identity. But now, e-fuel is very expensive to make as it relies on wind power and captured carbon dioxide.

During Monterey Car Week in 2023, Lamborghini showed the Lanzador , a 2+2 electric concept car with high ground clearance that is headed for production. “This is the right electric vehicle for us,” Foschini says. “And the production version will look better than the concept.” The Lanzador, Lamborghini’s fourth model, should arrive in 2028.
