The objective of this work was to develop a temperature sensor system that accurately measures core body temperature from an ear-worn device. Two digital temperature sensors were embedded in a hearing aid shell along the thermal gradient of the ear canal to form a linear heat balance relationship. This relationship was used to determine best fit parameters for estimating body temperature. The predicted body temperatures resulted in intersubject limits of agreement (LOA) of ±0.49 °C over a range of physiologic and ambient temperatures without calibration. The newly developed hearing aid-based temperature sensor system can estimate core body temperature at an accuracy level equal to or better than many devices currently on the market. An accurate, continuously worn, temperature monitoring and tracking device may help provide early detection of illnesses, which could prove especially beneficial during pandemics and in the elderly demographic of hearing aid wearers.
本工作旨在开发一种可从耳戴设备准确测量核心体温的温度传感器系统。两个数字温度传感器沿耳道的热梯度嵌入助听器外壳中，以形成线性热平衡关系。该关系用于确定用于估计体温的最佳拟合参数。在未经校准的情况下，预测的体温导致受试者间的（LOA）在生理和环境温度范围内为±0.49°C。新开发的基于助听器的温度传感器系统可以以与市场上许多设备相当或更好的精度水平估计核心体温。准确、持续佩戴的温度监测和跟踪设备可能有助于及早发现疾病，这在大流行期间和助听器佩戴者的老年人群中可能特别有益。
