Problems solved by technology

[0006] Most of the traditional energy harvesting devices harvest a single type of environmental energy, and the output power of single energy harvesting is usually low
For example, when collecting RF signal energy, due to the diversity of the environment, in an environment with low wireless signal power density, the collected RF energy will be greatly attenuated

Abstract

The invention discloses a cylindrical electromagnetic wave and vibration energy mixed collection device, which comprises a cylindrical dual-frequency microstrip antenna and a device for collecting vibration energy; The floor, the second antenna, and the first antenna; the metal ground plate serves as the common ground for the first antenna and the second antenna, and is a cylindrical metal patch, and the outer layer of the metal ground plate is covered with a cylindrical second antenna , the outer layer of the second antenna is covered with a cylindrical first antenna; compared with the common patch antenna, the cylindrical antenna of the present invention saves space to a large extent. Metal coils and permanent magnet sheets are added inside the cylinder to collect vibration energy. This design makes full use of the internal space of the cylinder and further saves space significantly. At the same time, since the metal coil and the permanent magnet are located inside the cylindrical antenna, the metal grounding plate in the middle plays a good role in isolation.

Description

technical field [0001] The invention belongs to the field of antennas for collecting electromagnetic wave energy and the field of collecting vibration energy. In particular, it relates to an integrated design of electromagnetic energy harvesting and vibration energy harvesting. Background technique [0002] With the rapid development of electronic technology, various wireless electronic products are flooding people's production and life. In addition to wireless keys, Bluetooth headsets, mobile phones, etc., which are widely used in daily life, in the industrial field, a large number of wireless sensor nodes are distributed in various environments to transmit monitoring data in real time to facilitate industrial control and production; in some special environments , such as high-radiation, high-temperature, high-altitude, and high-cold regions, it is not convenient for humans to monitor directly, and wireless sensors can be installed to complete monitoring and real-time tran...
