Abstract
An assembly converting thermal energy into electrical energy including: at least one temperature sensitive bimetallic strip arranged in a space delimited by a hot source and a cold source facing each other, the bimetallic strip extending along a longitudinal axis; at least one suspended element fixed in movement to the sensitive element and extending laterally from the sensitive element and including a free end; and at least one piezoelectric element suspended from a part fixed relative to the sensitive element and vibrated by the suspended element such that it is vibrated when the bimetallic strip changes configuration and the suspended element comes into contact with the piezoelectric element, the piezoelectric element being located outside the space defined between the bimetallic strip and the hot source and outside the space between the bimetallic strip and the cold source.
