Claim:
1. 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 the 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, wherein the detection system comprises a system for acquiring electric signals from the heat flow meters with a measurement resolution r with R being the radius of the circle circumscribed in the region of interest, S
