Flexible Film Temperature Sensors Produced for Wearable Tech

Murata is about to commence mass production of a range of surface-mounted NTC temperature sensors that are packaged on a flexible printed circuit (FPC) film. With an FPC thickness of approximately 100 µm, they can be easily routed inside complex designs and tight spaces. Owing to their low heat capacity, the sensor’s thermal responsiveness is excellent. Measuring 50.00 by 3.17 by 0.55 mm, they are designed for sensing the housing temperature of smartphones and tablets. They are also suitable for use in wearable products for sensing body surface temperature.

The FTNT55XH103FA1A050 sensor can measure temperatures in the range of -40 to + 125°C with an accuracy at 25°C of ±0.4°C. Resistance at 25°C is 10 kΩ ±1%.
