Abstract
A self-generation device, including: a piezoelectric patch; a vibration structure including an elastic element and a mass block connected to the elastic element; a vibration trigger structure which has a trigger threshold and is resilient, a bottom surface of the mass block is in contact with the vibration trigger structure. The elastic element is capable of driving the vibration trigger structure to press against the piezoelectric patch through the mass block after receiving a force; when a driven force exerted on the vibration trigger structure is greater than the trigger threshold, the vibration structure generates vibrations, so that the piezoelectric patch receives an alternating load and generates multiple deformations in a deformation space, a mechanical energy generated due to the vibrations of the mass block can be converted into electrical energy, and an electric energy production can be greatly increased.
