###### Abstract  
MFC (Microfiber composite) piezoelectric transducers are one of the smart composite materials used among others in alternative energy sources and autonomous wireless sensors which exploit vibrational energy. This work presents the theoretical and experimental investigations of the integration of MFC piezoelectric transducers on epoxy glass fiber composite material and explores the capacity of power generation based on a variety of ambient temperatures and frequencies. The study examined the use of ambient vibrational energy to power small electronic devices of wireless sensor networks which eliminates the need for external power, periodic battery replacement costs, and chemical waste from conventional batteries. The test was conducted using a laboratory stand equipped with a thermal chamber and an Instron ElectroPulse waveform generator which induces a concentric cyclic load to the laminated beam. Laminated MFC was loaded with a low-frequency range, controlled displacement under different moderate temperatures. The test was conducted at temperatures ranging from 25 to 60 degrees Celsius and at frequencies ranging from 5 to 25 Hz. The results show that the voltage generated by the transducer is highly affected by both temperature and frequency of excitation. the MFC piezoelectric transducer to an extremely wide range of temperatures, causing thermoelastic behavior to become significant. The uncertainty and complexity in predicting damage propagation in composite materials has limited the use of composite materials in all application scenarios. An effective solution is early damage detection via monitoring from integrated wireless sensors [8; 9]. As a result, energy harvesting from wind turbine blade vibration could be a promising technology for powering wireless sensor networks used for structural health monitoring where an ordinary battery pack is inadequate [10; 11]. In references [12; 13; 14] the authors described the integration of MFC into the composite material of a wind blade turbine in order to investigate the power generated by blade tip vibrations. The hypothetical outcomes were discussed and predicted, but they were not based on actual measured data. The proposed concept that wireless sensor networks used on wind turbine blades can monitor damage in glass fiber composite blades has made considerable progress. In references [15; 16; 17] the properties of a piezoelectric plate and a stack of two connected plates were investigated and addressed in relation to experimental results in this study. The applications of piezoelectric ceramics are expanding and studying more about the plate's characteristics and responsiveness helps to improve the intelligence of mechatronics systems. A linear electro-mechanically coupled finite element (FE) model for composite laminated thin-walled smart structures bonded with orthotropic MFCs with arbitrary piezo fiber orientation is developed in [16; 17; 18]. There are two types of MFCs: MFC-d31, in which the d31 effect dominates the actuation forces, and MFC-d33, which primarily uses the d33 effect. In reference [19; 20] the FE model is built using linear piezoelectric constitutive equations and is based on the Reissner-Mindlin hypothesis. Following that, isotropic or composite structures with cross-ply laminates integrated with MFC-d31 or -d33 patches with different fiber orientations are simulated on the MFC patches under a certain electric voltage. In references [21; 22] a vibration-based cantilever beam made from two popular piezoelectric laminated patches was the subject of an experimental study of its characteristic behaviors, and an energy harvesting modeling study carried out. The model was also shown to be more versatile and applicable for diversified harvesters with ambiguous or unknown parameters, which is impossible for traditional modeling methods to accomplish. In summary, this study conducted a typical experiment as well as harvesting modeling.
