Advances in medically accurate sensors pave the way to better health

01 December 2021

The rise in wearables and phone apps for personal fitness monitoring has been phenomenal in recent years and people are used to seeing data measuring their daily activities and body statistics. Sensors for wearable medical devices and apps are still evolving…

First-generation devices made simple measurements of inputs, recording what the wearer had done in a day, such as the number of steps taken, etc. These were useful for making and sticking to goals related to activities that may have improved the health of the wearer as long as their personal motivation was high. Second-generation sensors added health-related measurements, such as pulse rate measurements and heart rate, but this data is of little significant benefit to any but to the already keen fitness and sportsperson and has no value to the medical profession. 

Third-generation sensors are now becoming available that give highly accurate measurements of blood pressure, temperature, blood oxygen, pulse rate and respiration rate. With the capability to measure vital signs, wearables are no longer toys, they are regulated medical devices. The V-Sensor from Leman Micro Devices is the only sensor currently available that is capable of measuring vital signs to medical accuracy, completely calibration-free and without the use of any other devices.
