Abstract (en)
[origin: WO2011114048A2] This detector comprises a control device (140) designed to provide an electrical control signal (Vc) in response to a mechanical stress, and a transducer (118, 130), called an emission transducer, designed to convert the electrical control signal (Vc) into a detection signal. It furthermore comprises a piezoelectric element (114), called a supply piezoelectric element, connected electrically to the control device (140) and designed to provide, when mechanically excited, an electrical supply energy to the control device (140), and a mechanical excitation device (116) for exciting the supply piezoelectric element (114) on the basis of the mechanical stress.
