Apparatus for multi-sensor based wearable energy expenditure measurement device and method thereof

摘要

Unlike the existing system for calculating consumption energy based on human motion information and activity amount, the present invention detects and analyzes activity amount information, altitude information, and voice signal during daily life to more accurately calculate energy consumption of a user, The present invention relates to a multi-sensor-based wearable energy consumption measuring device and method applicable to healthcare including diet and the like. The present invention relates to a sensor unit including an acceleration sensor for measuring an activity amount, an altitude sensor for measuring a relative altitude of a user at a current position, and a vibration sensor capable of detecting vibration such as a PVDF film for detecting a voice signal, An analog signal processing unit for processing the sensor output, a control unit including a digital signal processing unit for calculating A / D conversion and energy consumption, a memory unit for storing energy consumption data, a USB Terminal, an interface using a Bluetooth protocol, a power unit for supplying power to the measuring device, and an application unit for displaying, storing and managing consumed energy.
