[0017] image 3 It is the comparison result of the output power of the high-efficiency broadband vibration energy harvester with elastic amplification mechanism (referred to as TDOF energy harvester) and the single cantilever beam vibration energy harvester (referred to as SDOF energy harvester) under different load resistances. It can be found that TDOF The maximum output power of the energy harvester is 511.7mW / g when the excitation frequency is 45.7Hz, the matching load resistance is 37kΩ and when the excitation frequency is 48.5Hz, the matching load resistance is 186kΩ 2 and 353.8mW / g 2 , while the maximum output power of the SDOF energy harvester under the same conditions above is 22.3mW / g 2 . In addition, the frequency bandwidth of the TDOF energy harvester reaches nearly 25Hz, while the frequency bandwidth of the SDOF energy harvester is only 8Hz.
[0018]The comparison results of the above embodiments can prove that the high-efficiency broadband vibration energy har...
