China helps Leman bring V-sensor to market
Leman (Lausanne, Switzerland), led by CEO Mark-Eric Jones and founded back in 2010, first emerged in the vital signs sensor area in 2017 (see Vital signs sensor could transform smartphones).
The three companies are now collaborating to produce a stand-alone device that can send clinically-accurate vital signs measurements, including blood pressure, wirelessly to a dedicated application on a smartphone. The device is expected to be available later in 2021.
The circular fob is 5cm in diameter and 2.5cm deep. When squeezed gently between thumb and forefinger it measures blood pressure using the Riva-Rocci method used by blood pressure cuffs. The Minshi also measures body temperature contactless. Bring the fob slowly towards the forehead until the smartphone app pings and displays temperature reading.
LMD’s V-Sensor measures five vital signs – blood pressure, blood oxygen (Sp02), respiration rate, pulse rate, and body temperature – to medical accuracy and results are delivered on-screen in less than one minute in LMD’s e-Checkup app. The sensor contains a MEMS pressure sensor embedded in flexible resin. The V-Sensor also contains an optical sensor, a temperature sensor and an ASIC to condition and digitize the signals from the sensors and drive LEDs and communication.
The V-Sensor and e-Checkup were developed for integration into smartphones and wearables and LMD claims to be the leader in medically-accurate vital signs measurement for personal healthcare.
WuQi Technology was established in 2016 to make chips for the IoT and AI sectors, focusing on IoT communication, security, and devices that use AI technologies. Its solutions include true wireless stereo, Wi-Fi, 3D facial recognition and others.
Shanghai Minshi Technology Co. Ltd was established early in 2015 to work on computer vision and neural networks and has developed a number of software and hardware products for security, education, healthcare and finance.
