采用JIRS30捕捉红外测温仪看不见的“核心温度”

Core Insights - The infrared thermometer is widely used in various fields such as healthcare, equipment monitoring, electric vehicle battery monitoring, and food processing due to its non-contact, rapid, and convenient features [1] - The JIRS30 thermal flow sensor from Shenzhen Baiyuda Technology Co., Ltd. is transforming the measurement of core body temperature by effectively converting surface temperature and thermal flow measurements into core temperature data, enabling non-invasive, continuous, and real-time monitoring [1] Group 1 - Core temperature refers to the internal or central temperature of an object, which is often more indicative of the true thermodynamic or physiological state [2] - In medical contexts, rectal and oral temperatures are considered closer to core body temperature, providing a more accurate reflection of fever conditions [2] - In industrial applications, the internal temperature of a motor winding is more indicative of its workload and safety status than the surface temperature [2] Group 2 - Differences between surface and internal temperatures are influenced by factors such as thermal conductivity and environmental effects [3] - A dual-sensor system comprising a thermometer and a thermal flow sensor is required to measure core body temperature from the skin surface, as the skin temperature is lower than the internal temperature [3] - The thermal flow sensor must possess high sensitivity, low noise, and extremely low thermal drift characteristics to effectively convert skin temperature and thermal flow measurements into core temperature data [3] Group 3 - Traditional infrared sensors used in wearable devices have limitations, including the inability to measure core temperature, bulkiness, environmental sensitivity, and calibration challenges in mass production [6] - The JIRS30 thermal flow sensor addresses these issues by utilizing thermoelectric materials integrated into a flexible polymer substrate, significantly reducing costs and enabling widespread application in smart wearables and core body temperature monitoring [6]
