demonstrated by using piezoelectric, electrostatic, electromagnetic, and triboelectric mechanisms for vibration energy harvesting. Even though the harvested power from these methods are small, it is sufficient to power small electronic devices, including light-emitting diodes, laser diodes, pH sensors, speed sensors, and toxic pollutant sensors. [6][7][8][9][10][11] Piezoelectric nanogenerator (PENG) has been most intensively studied because of its high conversion efficiency and compatible manufacturing process. [12][13][14][15][16][17][18] And it is found that piezoelectric materials polyvinylidene fluoride (PVDF) has demonstrated to be the largest piezoelectric constants in polymer. [19][20][21][22] To further this PVDF research for energy harvesting, Lee and co-workers introduced an enhanced piezoelectric energy harvesting by using graphene oxide which output voltage could reach to 4 V. [20] Wang and co-workers reported another enhanced sponge-like piezoelectric using PVDF, however the processing of this prototype is complicated and constrained in lab. [9] Recently, hybrid nanogenerators have attracted more and more attention. [23][24][25] Wang first described a hybrid triboelectric and electromagnetic harvester for the harsh environment. [23] Lee and co-workers reported a broadband nonlinear electromagnetic and triboelectric hybrid energy harvester. [24] However, the existing research using both electromagnetic and triboelectric method could harvest limited power due to the impedance mismatch. In this paper, we proposed a hybrid method using the piezoelectric and triboelectric method for energy harvesting. The designed PENG could greatly enhance the collection efficiency of mechanical energy with PVDF nanoparticles and PVDF/PTFE film, and the leaf-shaped woven fiber benefited the electric output for the TENG. In the end, a random test using finger tap was demonstrated the mechanical energy conversion performance by using eight light-emitting diodes (LED).

Piezoelectric elements are inevitable in modern day physics playing a vital role in many applications. Any piezoelectric element requires compression to produce energy in the form of a weak electrical ac signal. Mechanical vibrations are known to cause deflections which are enough to produce energy from the piezoelectric materials. In this paper, a review of the piezoelectric materials is made on their basic modes of excitation for producing energy. Also, various mechanisms and techniques used to harvest energy recently are presented and discussed extensively. Piezoelectric energy harvesting using MEMS is emphasized much as this is the era of micromechanical systems. Most of the piezoelectric energy harvesting systems relies on cantilever-oriented deflection to produce maximum vibration. In general cantilever beams fitted with piezoelectric materials produce electrical energy from mechanical vibration when deflected; hence detailed review on the different shapes of cantilever is also submitted. Significant parameters contributing to improved performance are dealt with special importance.
