Electrical power can be harvested from the ambient vibrations using piezoelectric materials. The Macro Fiber Composite (MFC) constructed employing piezoelectric fibers embedded in an epoxy matrix and coated with plyimide skin can offer strongly flexibility, excellent performance of electronics and high efficiency of energy capture. This is the excellent match for vibration energy harvesting, which make it well suited for low-power active device continuously. In this paper an innovative energy harvestor system is desigen adopt the MFC from the high altitude stable wind vibration source. Numerical model are simulated via the finite element analysis. The influence of the material parameters of the flexible matrix of MFC on the vibration energy harvesting is further studied and analyzed in this paper. The research shows that the MFC achieved a maximum output power of $13.5\mu \mathrm{W}$ with suitable flexible matrix material at the specific wind load $15\mathrm{m}/\mathrm{s}$. The advantages of energy harvesting using MFC and its potential applications in low power electronics and wireless sensors make a bright future in the aerospace industry.
