Currently, scientists from various fields are trying to find new ways of activating devices, considering the renewability of the used resources. The way to this goal can also be the search for the usability of various advanced materials in hitherto unexplored areas of technology. This article delves into the application of a non-contact infrared sensor MLX90614 to track dynamic temperature changes in a nitinol spring. By utilizing a controllable external power source, the material's temperature is manipulated through current modulation. This fluctuation is then captured and logged by a system that includes a microcontroller and a temperature sensor. The study's results provide vital information on the correlation between temperature and electrical properties, providing significant insights into the thermal behavior of nitinol springs for future research in this specialized field.
