ABSTRACT

In the human body, maintaining the core body temperature (CBT) is vital to ensure proper cellular and body functions. The temperature of 37°C (98°F) is the well-established baseline for CBT, but significant deviations to under 35°C (95°F) or over 40°C (104°F) can result in several health complications. If unnoticed in spaceflight, astronauts CBT could reach dangerously high levels when doing physically challenging tasks such as spacewalking or exercise. Therefore, a real-time multi-physiological parameter sensing system is needed to noninvasively monitor the status of crew members in space. The purpose of this paper is to test a novel temperature sensor developed by integrating thin sheets of polyvinylidene fluoride (PVDF), a temperature dependent dielectric material, into the sensor system designed as a substrate. This substrate interacts with the electromagnetic field created by the spiral sensor to result in a quantitative temperature monitoring sensor with a resolution of 1°C.

摘要

在人体中，维持核心体温 (CBT) 对于确保适当的细胞和身体功能至关重要。37°C (98°F) 的温度是 CBT 的公认基线，但显着偏差低于 35°C (95°F) 或超过 40°C (104°F) 可能会导致多种健康并发症。如果在太空飞行中不被注意，宇航员在进行太空行走或锻炼等具有挑战性的任务时，CBT 可能会达到危险的高水平。因此，需要一种实时的多生理参数传感系统来无创地监测太空中机组人员的状态。本文的目的是测试一种新型温度传感器，该传感器通过将聚偏二氟乙烯 (PVDF) 薄片（一种温度相关的介电材料）集成到设计为基板的传感器系统中。
