Newton Sweating Thermal Manikin System
topic
The Newton sweating thermal manikin is an articulated full-body mannequin with a distributed network of sweat pores across its surface connected to a precision liquid supply system that delivers controlled water flow rates to each body zone, simulating the spatial and temporal pattern of human perspiration while the manikin surface is maintained at skin temperature by embedded electrical heating elements in each independently controlled body segment. The system operates in a climate chamber with controlled temperature, humidity, and air velocity, enabling testing of complete clothing systems under steady-state and transient thermal conditions representing rest, moderate activity, and peak exercise scenarios. Data outputs include zone-by-zone thermal resistance and evaporative resistance maps revealing how clothing system performance varies across different body regions.
Role
The Newton sweating manikin provides the spatially resolved clothing system performance data that flat-plate testing and non-sweating manikins cannot deliver — revealing how moisture accumulation in specific garment zones during sweating degrades local thermal insulation and creates localised thermal discomfort hot spots, enabling garment engineers to optimise ventilation zone placement, material selection, and seam construction to eliminate these performance failures before consumer wear trials.
