Description

technical field

[0001] The invention belongs to the technical field of energy collection, and in particular relates to an electromagnetic vibration energy collector based on a Halbach array. Background technique

[0002] With the rapid development of Internet of Things technology and microelectronics technology, wireless sensor networks have been widely used in environmental monitoring, data transmission and other fields. In recent years, China's high-speed rail technology has developed rapidly, and sensors in the railway network have played a key role in the safety and stability of trains. At present, sensors in sensor networks mainly rely on traditional batteries to power them. However, traditional batteries have limited storage capacity, short service life, and great environmental hazards, which hinder the further development of wireless sensor networks.

[0003] Vibration energy is ubiquitous in the environment. Compared with solar energy, wind energy and other energy s...
