The tech healthcare revolution includes wearable products for blood pressure tracking and glucose monitoring

Tech leaders like Apple and Samsung are developing innovative non-invasive health features across a new range of devices like smartwatches and rings

Samsung is exploring the development of non-invasive glucose monitoring and continuous blood pressure checking, setting its sights on ambitious healthcare goals in a race with Apple and other tech giants.

The work is part of a broader push to put health features in a range of devices, including its just-announced Galaxy Ring, said Samsung executive Hon Pak, who is overseeing the effort. The company aims to eventually give consumers a complete picture of their well-being via sensors on different parts of the body and around the home.

Health tracking is already a key selling point of smartphones and watches, with Samsung, Apple and Google using the features to attract and retain customers.

Creating sensors for continuous blood pressure tracking and glucose monitoring would be particularly valuable breakthroughs. Apple has been working for years on a glucose reader that wouldn’t require users to prick their skin for blood — a potential boon for millions of diabetics.

“If we can do continuous blood pressure and glucose, we’re in a whole different ballgame,” Pak, Samsung’s mobile digital health chief, said during a wide-ranging interview. “I think that’s where everyone is trying to get to. We’re putting significant investment toward that.”

He wouldn’t comment on a timeline for either feature, but said he hopes non-invasive glucose monitoring could come to the market in some form within five years. “We are looking at everything from miniaturisation to the various different technology platforms that can do some type of glucose monitoring or anything in between,” Pak said.

The remarks follow Samsung’s announcement last week that it’s working on a ring with health sensors.

The Galaxy Ring product is scheduled to be released before the end of 2024 and will come in a range of colours and sizes, Pak said. The company is eyeing activity and sleep tracking for the ring, with more health features to come later.

Smart rings from companies like Oura offer an alternative for people who don’t like to wear a watch but still want to track their health metrics and sleep patterns.

“The ring represents that community of people who want health tracking that is more comfortable and less obtrusive,” Pak said. “It’s meeting a need of a specific population of people who want to track and measure, but in a different way.”

Pak said Samsung hasn’t finalised pricing on the Galaxy Ring, but — like the company’s Galaxy Watches — it probably won’t be compatible with Apple’s iPhone.

Developing a blood sugar monitor would be a more challenging task, but one that could have major rewards. Current products on the market typically require a blood draw or a prick in the skin — an obtrusive process.

Apple has been working on a non-invasive approach since around 2010 and has since made major progress, Bloomberg News has reported. Even so, a product remains years away.

The two companies also are working to improve blood pressure monitoring. Samsung smartwatches have long offered the ability to determine a user’s blood pressure, but the monitoring isn’t constant throughout the day and requires calibration against a standalone blood pressure checker.

Pak said Samsung is “evaluating all options” to improve its blood pressure features. The aim is to go longer without needing calibration. “We’ve been thinking long and hard about this,” he said.

Apple, meanwhile, is planning to add hypertension detection to its smartwatch later this year in a way that doesn’t require calibration but also doesn’t provide exact readings.

Instead, the watch will inform users that they may have elevated blood pressure. Apple’s expansion into health technology hasn’t gone entirely smoothly. It recently pulled a blood oxygen feature from the Apple Watch after a legal setback in its patent dispute with Masimo Corp.

Pak said traditional blood pressure readings aren’t “really that meaningful” other than showing a range of normal and abnormal. “Whether it’s Apple or others, I think we are trying to redefine blood pressure in a way that it was originally intended, which is: How much cardiovascular risk do you have?” he said.

Samsung is exploring new health features for its earbuds like measuring body temperatures and heart rates

Samsung also is exploring a range of different sensors for future versions of its earbuds.

The company is studying new ways to measure body temperature and heart rates, adding that the ear is a closer pathway to the heart than the wrist.

Data from the ear could be combined with wrist and ambient data to provide users with a more comprehensive picture of their health.

Mixed-reality headsets could be a new frontier for health as well, Pak said. Apple is poised to release its first product in that market next week when the Vision Pro goes on sale for $3,499 (€3, 210). Meditation and mental health could be key areas for such devices, he added.
