<p>The energy supply of microelectronic products mostly depends on chemical batteries with limited life that not only need to be replaced regularly, but also easily cause environmental pollution. Mechanical energy capture has attracted more and more attention in recent years. As a new type of self-sustaining micro power supply, the micro mechanical energy collector can convert the widely existing mechanical energy in the environment into electrical energy. It has the advantages of small size, light weight, convenient processing, reliable work, good environmental adaptability, and long life. It can almost replace traditional batteries,wired power supplies and micro batteries, supplying power for various micro wireless sensor products and embedded devices. For this reason, this paper aims at the problem of difficult power supply of a wireless sensor for equipment vibration monitoring, breaking through the limitation of single function of traditional vibration isolation and energy capture system, innovatively designng a mechanical vibration energy capture micro generator with multi-function vibration isolation and energy capture integration, models and analyzes the overall structure of the device and conducts theoretical derivation. It tests the output characteristics of the device under different load resistances. The test results show that the mechanical vibration energy capture micro generator can efficiently collect mechanical energy and convert it into electrical energy, which proves that the mechanical vibration energy acquisition device based on radial magnetic field designed in this paper is a practical energy acquisition system.</p>
