Abstract
A transducer for transducing time-related temperature variations into a difference in potentials includes an upper conductive electrode designed to be exposed to a time-related temperature variation to be measured, a lower conductive electrode, and at least one layer of pyroelectric material based on a III-V nitride directly interposed between the upper and lower conductive electrodes to generate, between the upper and lower conductive electrodes, a difference in potentials corresponding to the temperature variation even in the absence of external mechanical stress.
