Connected accessories are meant to accompany us on a daily basis. Watches and bracelets are not only extensions of the smartphone, but also tools to monitor important signals from our body. The first sensors to appear in watches (and some smartphones, especially Samsung) were used to measure heart rate. these are celebrities heart rate monitors.
Apple has contributed greatly to this electronics-focused “health and wellness” movement. L’Apple Watch Series 4 introduced electrocardiogram (or EKG for short) is used to measure the electrical voltage of the heart. This functionality is available on Apple Watch Series 5 and Apple Watch Series 6. Cupertino company, thanks to numerous patents Apple Watch’s EKGsemi-medical measuring instrument. And each country has to issue a medical certificate to activate the feature there. That was the case with the Galaxy Watch 3’s EKG, which was unlocked a few days after its presentation.
More recently, we’ve also seen another sensor reach watches and bracelets, called an oximeter. Measures oxygen saturation in the blood (SpO2) and the maximum amount of oxygen (VO2Max). Unlike an EKG, this sensor is not subject to scientific or medical certification. And now you find it very often.
Can measure blood sugar one hour after oxygen
Samsung may further strengthen that offer with one of these upcoming watches. A Korean media claims that the manufacturer has developed a sensor. measuring blood sugar (or more commonly, blood sugar level). This precaution is mandatory for diabetics, since too high a sugar level can lead to serious consequences (loss of consciousness, damage to certain organs, cardiovascular complications, infections, etc.). in France, 5.3% of the population has one form of diabetes.
Today, a patient should analysis from a drop of blood (and thus pierce your finger). According to Korean media, the sensor developed by Samsung will be less restrictive as it uses a laser. Be light. This method is called Raman spectroscopy. The idea is to analyze the composition of the blood using the light reflected by the sensor (for example, SpO2 oxygen measurement).
During the last CES in Las Vegas, a Japanese start-up Quantum Operations, reportedly showed off a prototype smartwatch. It is equipped with a sensor that measures blood sugar levels using Raman spectroscopy. In 20 secondsThe watch can measure the user’s blood sugar level. A very promising result.
A commercial launch is expected in the second quarter of 2021
According to Korean media, Samsung is ready to launch a connected watch this year equipped with this new technology. However, the launch would not take place before the second half of 2021. Therefore, it will be necessary to wait a few more months before we can test this new functionality. The first model equipped, Galaxy Watch Active 3 or watch galaxy 4. As a reminder, the Galaxy Watch Active 2 was introduced by Samsung in August 2019 and the Galaxy Watch 3 a year later. On the other hand, Korean media does not specify whether this blood glucose sensor will be subject to the same restrictions as the EKG. It makes sense to us, yes.
This isn’t the first time a large firm has struggled with diabetes and the convenience of patients who have to measure their blood sugar levels multiple times a day. We still remember an initiative developed by the department Google X from Google in 2014 (the group has not yet been named Alphabet). This project, called Smart Lens, was based on smart contact lenses that measure blood sugar in tears. Thanks to microcircuits, the lens could warn the user on his smartphone if a certain ratio was exceeded. The project was sold to a subsidiary, Alcon. Novartis. Unfortunately, three years later, Swiss pharmaceutical group abandons project.
