Student thesis: Master's Thesis


In the development of electrostatic energy harvester the natural frequency is in the range of 100 Hz ~ kHz This thesis designs a micro low-frequency vibration electrostatic energy harvester with natural frequency in the range of 1 ~ 2 Hz The electrostatic vibration energy harvester is of size 8 mm × 8 mm × 1 554 mm mass 1 8676 × 10-4 kg and the natural frequency ωn=1 7467 Hz When operating at this frequency ωn with external vibration amplitude 1000 μm and the frequency 4ωn with external vibration amplitude 225 μm the electrostatic vibration energy harvester can produce 0 31 μW and 0 859 μW respectively
