Abstract
The electronic device comprises a substrate provided with a surface comprising a region of interest, the thermal behavior of which is to be monitored, and a system for detecting hot spots located in the region of interest. The system for detecting hot spots comprises at least three separate heat flow meters arranged on the surface of the substrate outside of the region of interest.

1-13. (canceled)
An electronic device comprising:
- a substrate provided with a surface and at least an active or a passive electronic component arranged in a region of interest comprised in said surface,
- a detection system configured to detect hot spots located in the region of interest, the detection system comprising:
- at least three separate heat flow meters arranged on the surface of the substrate outside of the region of interest, each heat flow meters being sensitive to a temperature gradient and configured to measure values representative of a heat flow generated by a hot spot in the region of interest;
- and
- a calculation unit configured to analyze the values of the different heat flow meters, and to determine the location of a hot spot in the region of interest.
