| 摘要 |
<p>The invention relates to a device for converting vibratory mechanical energy into electrical energy (1), comprising: - a mobile mass (6); - a support (5); - a first beam (200) having its ends (201,202) built in respectively to the support (5) and to the mobile mass (6), the first beam exhibiting a first stiffness under elongation; - a second beam (100) made of a piezoelectrical material, the support and the mobile mass being linked by way of the second beam, the second beam exhibiting a second stiffness under elongation less than the first stiffness; - a first junction element (400) extending between the first and second beams, the bending stiffness of the assembly comprising the first beam, the second beam and the junction element being at least twice the bending stiffness of this same assembly devoid of the second beam.</p> |
