Abstract

The invention relates to the technical field of energy collection, in particular to an energy collector based on a magnetoelectric composite material and wearable equipment comprising the energy collector. The energy collector comprises a cover plate, a shell, a partition plate, a strong magnet block and a self-biased magnetoelectric composite material, wherein the cover plate is buckled at an opening of the shell, the partition plate divides the interior of the shell into two cavities, the strong magnet block and the self-biased magnetoelectric composite material are arranged in the two cavities respectively. The strong magnet block can move in the cavity in the radial direction of the self-biased magnetoelectric composite material to generate a changing magnetic field, the magnetoelectric composite material is excited to generate electric energy, conversion from environmental kinetic energy to electric energy is achieved, and the energy collector is simple in structure, small in size, convenient to carry and install and suitable for large-scale application and popularization. The wearable equipment comprises an energy collector based on the magnetoelectric composite material, andself-charging endurance or self-energizing can be achieved.
