Vibration energy collector is a green energy creation technology

which continuously "power" the system microelectronics by collecting the vibration energy of the engineering system and converting it into electrical energy. Based on the principle of electromagnetic induction

a combined single pendulum-electromagnetic vibration energy harvester is designed

and finite element simulation analysis of the induction characteristics and the influencing factors of the induction characteristics are carried out with COMSOL platform

and output performance experiments are conducted. The results show that the combined single pendulum-electromagnetic vibration energy harvester consisting of sleeve

rotor

pendant

magnet

coil and rope has a simple structure

light mass of about 200 g

small size about 30 cm3

with a natural frequency between 70 and 80 Hz. At a vibration frequency of 20 Hz and a small amplitude of 8 mm

the output voltage of the collector is 240 mV.
