The first measurement of blood pressure was made in 1896 by squeezing the flesh around an artery. This method remains the only non-invasive way to measure blood pressure, and 123 years later, there is only one device in the world that can do it without a cuff and to medical accuracy.
That device, the V-Sensor, is the technical implementation of proven medical science by Leman Micro Devices (LMD), the developer of regulated consumer healthcare products that is backed by major players within the mobile device industry.
There are many ways of tracking changes in blood pressure and a plethora of wearable and non-wearable devices now on the market that do it. These devices are not cuff-less, they require the input of cuff-measured blood pressure and then monitor changes over the next few days. Then a new calibration is necessary using a cuff again. That doesn’t help the one billion plus people in the world at risk of dying from hypertension because they do not know they have it – once they have used a cuff to calibrate a device, they will know that they’re ill and don’t need the device. Other wearable devices are simply not medically accurate, which is even worse.
