摘　　要：体温是人体重要的生理参数,在医学上用于反映人体的生理状态和健康状况。目前市面常用体温计主要分为接触式与非接触式,大多用于快速体温测量,不易于实时监测体温的变化,该文介绍了一种基于NTC的新型的可穿戴无线体温监测系统,通过NTC感知温度的变化,并经过放大滤波以及校零、校准,再将温度数据通过蓝牙实时上传至手机APP,实现对体温的实时精确测量。Body temperature is an important physiological parameter of the human body and is used in medicine to reflect the physiological state and health status of the human body.At present,the commonly used clinical thermometers on the market are mainly divided into contact and non-contact types.Most of them are used for rapid body temperature measurement,and it is not easy to monitor body temperature changes in real time.This article introduces a new wearable wireless body temperature monitoring system based on NTC,which senses through NTC.The temperature changes are amplified and filtered,zeroed,and calibrated,and then the temperature data is uploaded to the mobile phone APP via Bluetooth in real time to achieve real-time accurate measurement of body temperature.
