Abstract

The invention discloses a fractal structure-based small broadband vibration transducer, which comprises a plurality of transduction units and a frame body, wherein an electrode is arranged in the frame body; each transduction unit comprises a plurality of peano fractal curve fractal structures which are connected with one another; at least one end of each peano fractal curve fractal structure is fixedly connected with the frame body; the transduction units including the fractal structures selectively receive vibration according to the environmental vibration frequency when the environment vibrates; the transduction units obtain the stress and transduce the stress into electric energy according to the received vibration; and the frame body leads the electric energy outside through the electrode. According to the fractal structure-based small broadband vibration transducer, the frequency band responsivity can be expanded; and the transduction energy is high.

Description

technical field [0001] The invention relates to the technical field of vibration transducers, in particular to a small broadband vibration transducer based on a fractal structure and a packaging method thereof. Background technique [0002] In recent years, with the increasing development of wireless networks and portable electronic devices, the disadvantages of traditional batteries have attracted increasing attention, such as large volume and environmental pollution. If the device is in some special environment, it is very difficult to replace the battery, so people hope to replace the traditional battery with recyclable green energy. Among them, energy harvesting technology has attracted the most attention. Energy harvesting technology mainly collects energy from the environment spontaneously through the transducer, and its essence is the process of converting various energies in the natural environment where the transducer is located into usable energy by using various ...
