EVALUATION SYSTEM FOR MONITORING OF VITAL PARAMETERS AND ACTIVE BODY CLIMATE CONTROL

摘要

This work presents a textile integrated evaluation system for active body climate control. The evaluation system registers several vital parameters of the user (skin temperature, skin relative humidity, heart rate, breathing rate and 3D acceleration data), its current subjective feedback and some surrounding parameters (temperature and relative humidity) and thus automatically controls the air ventilation level inside a cooling vest. For the climate control, a regulation algorithm influencing the body heat exchange processes and leading to thermal comfort at different workloads and different surrounding conditions is heuristically designed. In addition, a field study is conducted. This study involves 11 test persons and aims at validating the sensor data of the evaluation system and determining the energy expenditure of the body from the sensor data by analyzing the correlation between these data and the reference data of a spirometer. Besides, a verification of the suitability of the evaluation system for daily use and a validation of the implemented regulation algorithm is conducted.
