Description
technical field [0001] The invention relates to a piezoelectric energy recovery device, in particular to a device combined with a spring system and piezoelectric energy recovery, and belongs to the field of converting deformation energy generated by extrusion into electric energy and collecting it for use in electronic products. Background technique [0002] According to the way of providing electric energy, electronic products can be divided into two types: active and passive. Because the former is powered by batteries, the power is relatively stable and meets the energy demand of electronic products, so it has been widely used at present. However, for many dangerous occasions where power cannot be provided, batteries are difficult to replace, or are inflammable and explosive, the problem of battery replacement is difficult to solve, and passive power supply has attracted more and more attention. Therefore, people begin to demand battery substitutes, the purpose of which i...
