A new generation of warm-body sweating manikins: technological innovation leads to a new era of comfort research

In the field of human thermal comfort research, the new generation of warm-body sweating dummies is setting off a technological revolution and opening a new era for related research.

Compared with traditional warm-body sweating dummies, the new generation of products has achieved major breakthroughs in core technology. The accuracy of its body temperature simulation has made a qualitative leap. Relying on highly sensitive thermistors and intelligent temperature control algorithms, it can simulate the dynamic changes of human core body temperature and surface temperature with extremely small errors. For example, when simulating the transition of the human body from a quiet state to a state of exercise and fever, the dummy can accurately follow the physiological temperature rise curve of the human body, and steadily increase the body temperature in stages, truly reflecting the heat dissipation under different activity intensities.

Sweating simulation technology is an innovative highlight. The new generation of dummies is equipped with a microscopic bionic sweat gland structure. These tiny "sweat glands" can not only accurately control the amount of sweating, but also intelligently adjust the secretion rate and component ratio of sweat according to the ambient humidity, temperature and the dummy's own "body temperature", which is highly consistent with the sweating mechanism of the human body in a complex environment. For example, in a high temperature and high humidity environment, the mannequin will automatically increase the electrolyte concentration in sweat, just like the real human body's response to maintain the osmotic pressure balance in the body.

From the perspective of sensor integration, the new generation of warm-body sweating mannequins can be called "mobile thermal comfort monitoring stations". It is covered with various types of sensors. In addition to conventional temperature and humidity sensors, it also has new heat flow sensors, wind speed sensors, and skin galvanic response sensors. These sensors work together to capture subtle changes in the microclimate of the mannequin surface and clothing. Taking the heat flow sensor as an example, it can accurately measure the heat passing through the clothing per unit time, providing key data for evaluating the thermal insulation performance of the clothing; while the skin galvanic response sensor can indirectly reflect the degree of heat stress of the human body and further improve the thermal comfort evaluation system.

In practical applications, the new generation of warm-body sweating mannequins are widely used in many fields. In the field of architectural environment design, researchers use it to simulate the thermal comfort of residents in different seasons and different indoor layouts, and optimize the air conditioning ventilation system and lighting design; in the development of transportation interiors, through dummy testing, the seat material and the layout of the vents in the car are accurately adjusted to improve the comfort of passengers on long-distance trips; in the field of outdoor equipment manufacturing, it helps improve the thermal performance of high-performance sportswear, tents and other products, so that outdoor enthusiasts can enjoy a comfortable experience.

In short, the new generation of warm-body sweating dummies, relying on cutting-edge technological innovations, is reshaping the research pattern of human thermal comfort with unprecedented depth and breadth, creating a more comfortable and pleasant living, working and travel environment for people.
