Abstract

A change in body temperature can be a symptom of an unhealthy status, or can reflect physical activity and medicine intake. Temperature measurements over the skin are practical and non-invasive, but a reliable evaluation of core temperature requires invasive measurements in natural body cavities. Dual-heat-flux thermometry offers an indirect method to estimate deep body temperature from the surface of the skin with four sampling points on the same device, that however is currently wired, bulky and rigid. Therefore, its comfort and applicability are limited. Ultra High Frequency (UHF) Radio Frequency IDentification (RFID) devices, instead, can enable non-invasive wireless monitoring of temperature over the skin by means of epidermal antennas with embedded temperature sensors. By combining RFID technology with dual-heat-flux method, this paper presents a preliminary design of a dual-heat-flux epidermal RFID thermometer. It is flexible and more compact, and can be read wirelessly by an hand-held reader.

柔性多层传感器无线实现体温双热流监测

体温的变化可能是不健康状态的症状，也可能反映出身体活动和药物摄入量。皮肤上的温度测量是实用且非侵入性的，但可靠的核心温度评估需要在自然体腔中进行侵入性测量。双热通量测温仪提供了一种间接的方法，通过在同一设备上的四个采样点来估计皮肤表面的深层体温，然而目前这种设备是有线的，体积庞大且坚硬的。因此，其舒适性和适用性受到限制。相反，超高频(UHF)射频识别(RFID)设备可以通过带有嵌入式温度传感器的表皮天线实现对皮肤温度的非侵入式无线监测。将RFID技术与双热流通量法相结合，初步设计了一种双热流通量表皮RFID体温计。它更灵活，更紧凑，可以通过手持阅读器进行无线阅读。
