In high - end medical NTC sensors used in devices such as MRI - compatible patient temperature monitoring systems, these advanced materials enable an accuracy of ±0.05°C within the range of 30°C - 42°C. This is a significant improvement compared to the previous ±0.1°C accuracy in similar applications. The use of these materials also reduces the long - term drift in resistance values. Laboratory tests show that over a period of one year, the resistance drift of NTC sensors made with new materials is less than 0.1%, while traditional sensors may experience a drift of up to 0.5%. This enhanced stability is crucial for applications where continuous and reliable temperature monitoring is required, such as in pharmaceutical cold - chain storage. 1.2 Improved Manufacturing Processes Advanced manufacturing techniques, including thin - film deposition and micro - machining, are being adopted to fabricate NTC sensors. Thin - film deposition allows for the creation of extremely uniform NTC films on substrates. This uniformity results in better - matched resistance values among sensors produced in the same batch. For instance, in a batch of 10,000 NTC sensors for use in data center server temperature monitoring, the standard deviation of resistance values at 25°C can be reduced to within ±0.2% using thin - film deposition technology, compared to ±1% in sensors made with traditional thick - film processes. Micro - machining is used to precisely control the geometry of the NTC sensing element. By creating smaller and more accurately shaped sensing areas, the response time of the sensor is improved. Some newly developed NTC sensors with micro - machined elements can achieve a response time of less than 50 milliseconds in air, which is much faster than the typical 100 - 200 milliseconds response time of traditional sensors. This fast response time is beneficial for applications that require rapid detection of temperature changes, such as in high - speed industrial processes. 2.
