The Study of the Influence of Temperature and Low Frequency on the Performance of the Laminated MFC Piezoelectric Energy Harvester

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 theoretical experimental investigations integration on epoxy glass fiber material explores capacity power generation based a variety ambient temperatures frequencies. The study examined use to small electronic devices sensor networks eliminates need for external power, periodic battery replacement costs, chemical waste from conventional batteries. test was conducted using laboratory stand equipped with thermal chamber an Instron ElectroPulse waveform generator induces concentric cyclic load laminated beam. Laminated loaded low–frequency range, controlled displacement under different moderate temperatures. at ranging 25 60 degrees Celsius frequencies 5 Hz. results show that voltage generated by transducer is highly affected both temperature frequency excitation.
