呼吸防护的有效性取决于许多因素，包括佩戴的持续时间和时间。迄今为止，这些因素只能通过直接观察呼吸器使用者来评估。我们描述了位于面罩内的数据记录温度和湿度传感器（iButton Hygrochron）的新用途，通过监督实验（第1阶段）和无监督佩戴试验（第2阶段）量化呼吸器佩戴时间。此外，在第1阶段，将面罩内温度与呼出气温度的测量值进行比较。我们发现戴口罩时，湿度比温度反应更快，因此它被认为是一种更敏感的佩戴时间测量方法，特别是在短时间内。监督测试表明，这种方法可以提供准确和精确的磨损时间的估计，虽然该方法可能不适合在环境湿度高的情况下使用。面罩内温度与呼出气体温度密切相关，呼出气体温度与肺部炎症有关。这项技术可以提供一种有用的方法来评估在现实生活中保护健康的有效性。
The effectiveness of respiratory protection is dependent on many factors, including the duration and times during the day when it is worn. To date, these factors could only be assessed by direct observation of the respirator user. We describe the novel use of a data-logging temperature and humidity sensor (iButton Hygrochron) located inside a facemask to quantify respirator wear-time through supervised experiments (Phase 1) and an unsupervised wearing trial (Phase 2). Additionally, in Phase 1 the in-mask temperature was compared with measurements of exhaled breath temperature. We found humidity responds more rapidly than temperature to donning a mask, so it was considered a more sensitive measure of wear-time, particularly for short durations. Supervised tests showed that this method can provide accurate and precise estimates of wear-time, although the approach may be unsuitable for use in situations where there is high ambient humidity. In-mask temperature is closely associated with exhaled breath temperature, which is linked to lung inflammation. This technique could provide a useful way of evaluating the effectiveness of respirators in protecting health in real-life situations.
