Impact of dielectric loss on performance of piezoelectric energy harvester

The goal of the project is to investigate the impact of the dielectric loss on the performance of piezoelectric energy harvester.

Green technologies such as piezoelectric energy harvester are gaining importance in the application of low-power electronics and sensors. Despite many advances, limited amount of information is available in the open literature on the impact of the dielectric loss of the piezoelectric material on its electromechanical coupling factor.

This project seeks to propose a model that provide this linkage. The developed model could be used by the designers of piezoelectric energy harvesters of varying designs and materials.

The student will be based at School of Engineering at Built Environment located in Nathan campus, working under Dr Faisal Mohd-Yasin's research group. This group has solid research experiences in circuit design and piezoelectric MEMS, with access to state-of-the-art equipment in electronic instrumentation and micro-fabrication technologies. In addition, we will also train the student in giving presentations, writing conference and journal papers, as well as compiling PhD thesis in timely fashion.

Funding Notes

• Griffith University funds both domestic and international PhD candidates on a competitive basis and is one of few institutions to offer both a tuition fee waiver and a living stipend.
• To be eligible and competitive for a Griffith University Postgraduate Research Scholarship (domestic; View Website) or a Griffith University International Postgraduate Research Scholarship (international applicants; View Website) you need to have First Class Honours or equivalent research experience.
• First-author peer-reviewed publications in international journals are advantageous.
• Top-ranked candidates will be selected from among applicants to proceed to a formal PhD and scholarship application through Griffith University, with the support of the prospective supervisory team.
• Applications can be received and processed year-round for our four intakes. Click here for key dates.

Location

It is expected that the PhD candidate be based in-person on Griffith’s Nathan campus in Brisbane, Queensland, Australia, even though some travel to Griffith’s Gold Coast campus may be required.
