Design of a Device for Measuring the Parameters of the Microenvironment under Protective Face Masks

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 (CO
₂
) 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 CO
₂
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 to determine the parameters of the microenvironment under protective masks of a different type.
