Method and device for converting mechanical energy into electrical energy |
摘要 |
A method for converting mechanical energy into electrical energy by at least one piezoelectric element and at least one variable capacitor. The method: a) mechanically deforms the piezoelectric element; b) recovers charges produced by the deformation of the piezoelectric element; c) transfers the charges from the piezoelectric element to the capacitor; d) modifies the capacitance of the capacitor; and e) recovers at least some of the electrical energy. A device for converting mechanical energy into electrical energy includes a piezoelectric element and a variable capacitor. The piezoelectric element is capable of transferring charges to the capacitor.
