Title: Design of a device for measuring the parameters of the microenvironment under protective face masks
Keywords: measurement device, face masks, COVID-19, microenvironment, CO2, thermophysiological comfort

Abstract: Wearing face masks in a pandemic is one way to limit the spread of viral particles. However, their use leads to a change in the dissipation of heat from the face to the environment. As a result, a microenvironment with increased air humidity, air temperature and carbon dioxide (CO2) concentration is formed under the mask. The aim of the paper is to present the design of a device for continuous measuring the temperature, humidity and concentration of CO2 in the microenvironment under protective face masks made of textiles. The requirements for the creation of such a device are complex: to fit well under the mask; not to impede the heat and mass transfer processes through the face mask; to support the sensors; to be reusable and to allow disinfection. The device will be used for the determination of the parameters of the microenvironment under protective masks of a different type.
