Bluetooth-enabled V-Sensor checks up on the wearer

Leman Micro Devices (LMD) has announced that its V-Sensor is now Bluetooth-enabled. Coupled with LMD’s e-Checkup app, which measures blood pressure, body temperature, pulse rate, respiration rate and blood oxygen, the technology extends to the wearables market and enables medically-accurate measurement from a wearable device for the first time.

LMD clarifies that while many wearables claim to measure blood pressure without a cuff, they all depend on a cuff for personal calibration and frequent recalibration and none measure temperature and blood pressure. There are also none that are certified medical devices, whereas V-Sensor is expected to obtain full international regulatory approval including meeting the stringent requirements of NMPA as well as FDA and CE for safety, accuracy and reliability.

V-Sensor and LMD’s e-Checkup app have been developed for full integration into smartphones and are currently being evaluated by major manufacturers worldwide.

LMD has now demonstrated the use of the V-Sensor working through a Bluetooth-enabled low energy device for wearable device use. Integration into a range of wearables, including watches, will enable personal responsibility for monitoring and improving overall health, as well as alerting people to potential health issues. For example, while high blood pressure is a global problem, many people are unaware they have it, and the ability to self-monitor frequently through the use of a V-Sensor-enabled wearable, could quickly and simply identify a problem.

V-Sensor uses the proven Riva-Rocci technique of occluding the arteries on the tip of the index finger for accurate blood pressure measurement, with no other device or calibration required. V-Sensor technology built into a wearable device also enables accurate body temperature measurement, often an early symptom of illness or infection.  The sensor also delivers blood oxygen level, pulse and respiration rates in seconds. Body temperature is measured by the thermopile built into the V-Sensor and only requires a quick forehead scan.

Leman Micro Devices (LMD) is based in Lausanne, Switzerland. It developed its e-Checkup system for integration into smartphones. This sensor combined with an easy-to-use app is claimed to be the world’s first miniaturised system to measure blood pressure and other vital signs to medical accuracy. LMD is an ISO 13485 certified company.
