Even minor deviations during fabrication can result in calibration drift, impacting the sensor’s accuracy over its operational lifespan , a particularly critical concern in medical and automotive applications where measurement tolerances are extremely tight.
Other Challenges
Sensitivity to Environmental Stress
Thin film NTC temperature sensors, while compact and highly responsive, can be susceptible to mechanical stress, humidity ingress, and chemical exposure if not adequately encapsulated. In harsh industrial or outdoor environments, long-term reliability can be compromised, requiring additional protective packaging that can offset the miniaturization advantages these sensors inherently provide. Balancing protection with form factor remains an ongoing engineering challenge for sensor designers and OEMs alike.
Supply Chain Constraints and Raw Material Availability
The production of thin film NTC sensors relies on specialty metal oxides and thin film deposition materials, the supply of which can be subject to geopolitical disruptions and raw material price volatility.
