用于精确表征诸如皮肤的软生物组织的热特性的非侵入性方法可以产生关于生理健康状态的重要细节，包括在皮肤损伤后恢复期间的关键间隔。在这里，我们介绍定量测量和表征方法，允许使用薄的皮肤状电阻传感器平台快速，准确地确定软材料的热导率。在8个不同位置的皮肤和6个不同的合成皮肤模仿材料的传感器尺寸，测量时间和表面几何形状（平面，高度曲线）的系统评估验证数据解释和参数提取的简单的比例法则。作为可能性的一个例子，在从暴露于紫外线辐射（晒伤）和与局部加热和冷却相关的应激源恢复期间，可以监测皮肤（掌侧前臂）的热特性的变化。更一般地说，这里描述的结果有助于对广泛类别的生物和非生物软材料进行快速，非侵入性的热测量。(c)2018作者爱思唯尔有限公司出版
Noninvasive methods for precise characterization of the thermal properties of soft biological tissues such as the skin can yield vital details about physiological health status including at critical intervals during recovery following skin injury. Here, we introduce quantitative measurement and characterization methods that allow rapid, accurate determination of the thermal conductivity of soft materials using thin, skin-like resistive sensor platforms. Systematic evaluations of skin at eight different locations and of six different synthetic skin-mimicking materials across sensor sizes, measurement times, and surface geometries (planar, highly curvilinear) validate simple scaling laws for data interpretation and parameter extraction. As an example of the possibilities, changes in the thermal properties of skin (volar forearm) can be monitored during recovery from exposure to ultraviolet radiation (sunburn) and to stressors associated with localized heating and cooling. More generally, the results described here facilitate rapid, non-invasive thermal measurements on broad classes of biological and non-biological soft materials. (c) 2018 The Authors.
