$GTCH The Optical Blood Pressure analysis system works by illuminating the finger's skin with miniature LED light (Emitted by the sensing system, and controlled by the embedded microcontroller) and by further capturing the light that is scattered and modulated by the pulsation of the user's skin arterioles. These signals are fed into algorithms to mathematically calculate the body's blood pressure. qTerm device will be enhanced by the addition of a high-sensitivity optical sensor and microchip on its PCB board. The physical dimensions of the device are expected to grow slightly. GBT is currently evaluating advanced optical electronic systems. An integrated optical solution consumes low power and provides high accuracy. The device also received its TM (Trademark) allowance notice and will present it on the product/package as required by the United State Patent Office. The qTerm device is targeted to measure body temperature, blood pressure, blood oxygen level and heart rate – all with a simple touch of the finger.
