Les futures Samsung Galaxy Watch 4 et Apple Watch Series 7 embarqueraient une fonction pour mesurer le taux de glucose dans le sang (glycémie) et faciliteraient ainsi la vie des personnes atteintes de diabète.
La montre connectée Apple Watch permet de détecter des irrégularités du pouls pouvant signaler une fibrillation atriale dans la population générale et amener les patients à contacter un médecin pour un suivi, selon une large étude américaine présentée le 16 mars au congrès de l'American College of Cardiology (ACC) à La Nouvelle-Orléans.

Un nouveau capteur qui va venir protéger votre peau
Apple has hired a small team of biomedical engineers to work at a nondescript office in Palo Alto, miles from corporate headquarters. They are part of a super secret initiative, initially envisioned by the late Apple co-founder Steve Jobs, to develop sensors that can non-invasively and continuously monitor blood sugar levels to better treat diabetes, according to three people familiar with the matter.
Such a breakthrough would be a "holy grail" for life sciences. Many life sciences companies have tried and failed, as it's highly challenging to track glucose levels accurately without piercing the skin.
The initiative is far enough along that Apple has been conducting feasibility trials at clinical sites across the Bay Area and has hired consultants to help it figure out the regulatory pathways, the people said.
… speculation has been flying around since the company snapped up about a dozen biomedical experts from companies like Vital Connect, Masimo Corp, Sano, Medtronic, and C8 Medisensors. Some of these people joined the secretive team dedicated to glucose, sources said, while others are on Apple Watch team.
One of the people said that Apple is developing optical sensors, which involves shining a light through the skin to measure indications of glucose. Accurately detecting glucose levels has been such a challenge that one of the top experts in the space, John L. Smith, described it as "the most difficult technical challenge I have encountered in my career." The space is littered with failures, as Smith points out, but that hasn't stopped companies from continuing to attempt to crack this elusive opportunity.
To succeed would cost a company "several hundred millions or even a billion dollars," DexCom executive chairman Terrance Gregg previously told Reuters.
The breakthrough would be a boon for millions of people with diabetes, spur new medical research and open up a potential market for consumers to track their blood sugar for health and wellness insights. It could turn the Apple Watch into a "must have" rather than a "nice to have" for people who would benefit from an easier way to track their blood sugar.
Apple isn't the only technology company eyeing opportunities in the space. Verily, Google's life sciences team, is currently working on a "smart" contact lens to measure blood sugar via the eye (but read “Google’s ‘Smart Lens’ for Glucose Monitoring Not Such a Smart Idea After All!”) and it partnered up with DexCom in 2015 to develop a glucose-sensing device no bigger than a bandage.

Non-invasive glucose monitoring devises are being called the holy grail for “treating” diabetes. To be more precise, such a device would be part of treatment that warns patients when their glucose level is too high or too low. Patients will still have to inject themselves with insulin, the dosage of which may perhaps be determined by the device. That, of course, would require FDA approval as a medical device. The TRUE holy grail would be a device that monitors glucose levels AND automatically delivers the proper dose as needed – i.e., an artificial pancreas.
The NIH is currently asking for pubic feedback on using smartphones and wearables to collect health and lifestyle data for its Precision Medicine Initiative — an initiative that hopes to collect data on more than 1 million individuals. The NIH’s Precision Medicine Initiative is described as:
a bold new enterprise to revolutionize medicine and generate the scientific evidence needed to move the concept of precision medicine into every day clinical practice
What exactly that means is a bit nebulous, but a New England Journal of Medicineperspective sheds some light:
Ultimately, we will need to evaluate the most promising approaches in much larger numbers of people over longer periods. Toward this end, we envisage assembling over time a longitudinal “cohort” of 1 million or more Americans who have volunteered to participate in research.
Qualified researchers from many organizations will, with appropriate protection of patient confidentiality, have access to the cohort’s data, so that the world’s brightest scientific and clinical minds can contribute insights and analysis.
The NIH is specifically asking the following:
Willingness of participants to carry their smartphone and wear wireless sensor devices sufficiently throughout the day so researchers can assess their health and activities.Willingness of participants without smartphones to upgrade to a smartphone at no expense.How often people would be willing to let researchers collect data through devices without being an inconvenience.The kind of information participants might like to receive back from researchers, and how often.Other ways to conveniently collect information from participants apart from smart phones or wearable devices.
It’s exciting to see the NIH see the potential of digital health. They specifically mention how smartphones and wearables can be utilized to collect a wide variety of data: location information, mobile questionnaires, heart rate, physical activity levels, and more.
There is already a robust discussion taking place in the comments section at the NIH website, and we encourage our readers to contribute.

A newly published Apple patent application that details ways to improve a wrist-based pedometer could represent another piece of evidence pointing to an iWatch.
The application, “Wrist Pedometer Step Detection,” came out of the U.S. Patent and Trademark Office today. This is part of the standard patent process toward issuance. It details ways to improve step detection when someone is wearing a pedometer on a wrist.
In the patent application’s implementation, the pedometer might be able to “automatically determine that the pedometer is being worn on a user’s wrist.”
Pedometers, the application points out, are often attached to a user’s trunk – on the waist or pants or shirt pocket. A commonly used algorithm to measures steps, however, doesn’t work as well when the pedometer is on a wrist, because the arm’s movement can interfere with the measurement of acceleration.
Apple’s patent application would overcome this by filtering the measured movement or inferring steps from previous measurements, leading to more accurate step counts and distance estimation. Additionally, the document notes, “users do not have to specify where the pedometer is being worn” because the software will compensate.
The U.S. Patent and Trademark Office just granted Apple a patent for a new kind of biometric sensor that, unlike other wearables we've seen so far, connects to you via your ear. The patent applies to a sensor that can be embedded in a pair of earbuds or headphones, which then hoovers up wearer data like heartbeat, body temperature, or even how much you're perspiring when you hit the gym.
How the sensor intends to do that, however, isn't explicitly outlined in the filing. AsAppleInsider first pointed out, U.S. patent #8,655,004 concerns a "sports monitoring system for headphones, earbuds and/or headsets" to be used "during exercise or sporting activities." Originally filed in 2007, the patent suggests Apple has apparently been experimenting with new ways to cull together biometric data for quite some time now.
