Abstract

The core and skin temperature of an infant are essential physiological indicators of the baby’s health and an important reference in the selection of baby clothing. The main idea for this is that parents often wrap their infants in covers and clothing based on their own subjective experience, and infants do not have the ability to express themselves verbally, which is likely to result in over- or under-wrapping, leading to babies feeling too hot or too cold and even causing illness. Accurately predicting and determining infants’ skin and core temperatures at different ambient temperatures is a critical concern in infant clothing research. While the overall skin temperature of infants cannot be understood using traditional body temperature robotic measurements, this article develops a three-dimensional infant thermoregulation model with a geometrical appearance similar to an accurate infant model based on finite element method. Through geometric model construction, cell meshing, boundary condition loading, and user-defined functions program debugging, infants’ body surface and core temperature distribution under different ambient temperatures are calculated. The results were compared with published clinical temperature tests and validated, which were in good agreement with the actual test results and proved the validity of the model calculation. Providing a new method for infant temperature prediction, the findings of this study put forward a scientific reference for infant dressing selection and research on intelligent clothing.
基于有限元法的几何精确三维婴儿体温调节模型
婴儿的核心和皮肤温度是婴儿健康的基本生理指标,也是婴儿服装选择的重要参考。这样做的主要思路是,父母经常根据自己的主观经验给婴儿裹上被子和衣服,婴儿没有语言表达能力,这很可能导致包裹过多或过少,导致婴儿感觉太热或太冷,甚至引起疾病。准确预测和测定婴儿在不同环境温度下的皮肤和核心温度是婴儿服装研究的一个关键问题。虽然使用传统的体温机器人测量无法了解婴儿的整体皮肤温度,但本文开发了一个三维婴儿体温调节模型,其几何外观类似于基于有限元方法的精确婴儿模型。通过几何模型构建、单元网格划分、边界条件加载和自定义函数程序调试,计算不同环境温度下婴儿体表和核心温度分布。将计算结果与已发表的临床温度测试结果进行对比验证,结果与实际测试结果吻合较好,证明了模型计算的有效性。本研究结果为婴儿体温预测提供了一种新的方法,为婴儿服装的选择和智能服装的研究提供了科学参考。
