Multiscale modelling and optimization of flexoelectric nano structures

Xiaoying Zhuang, Chair of Computing Science and Simulation Technology, Institute of Photonics, Department of Maths and Physics, Leibniz University Hannover


Flexoelectricity is the generation of electric polarization under mechanical strain gradient or mechanical deformation subjected to an electric gradient (converse-flexo). Flexoelectricity is a more general phenomenon than the linear change in polarization due to stress, the piezoelectric effect. In contrast to piezoelectricity, flexoelectricity exists in wider range of centrosymmetric materials especially nontoxic material useful for biomedical application. Flexoelectricity grows dominantly in energy density when scale reduces to submicro or nano, meaning the promise of enabling self-powered nano device such as body implant and small-scale wireless sensor. In Hannover, multiscale characterization of flexoelectric materials and design of flexoeletric structures based are being carried out including topological optimization for single/multi-phase materials, 2D flexoelectric materials characterization, and atomistic to continuum dynamic flexoelectric modelling as shown in Fig. 1. Phononic metamaterials for enhancing the flexoelectricity is being utilized and intergrated in the design to outperform the current design of nano energy harvesters. Interesting phenomenon of utilizing topological insulators and metaplates of phononic structures will be shown that can enhance the performance of nano energy harvester.



Dr. Xiaoying Zhaung ’s key research area is computatioanl materials design for nano composites, metamaterials and nanostructures as well as computational methods for multiphysics and multiscale modelling. Dr. Xiaoying Zhuang obtained her PhD in Durham University, UK in 2011, which is followed by her postdoc in Norwegian University of Technology in Trondheim and then as a faculty staff in Tongji University. In 2015, she was awraded with the Sofja Kovalevskaja Programme from Alexander von Humboldt Foundation that brought her to Germany and she focused on the modelling and optimization of polymeric nanocomposite. Her onging ERC Starting Grant is devoted to the optimization and multiscale modelling of piezoelectric and flexoelectric nano structures. In 2018, she was awarded with Heinz-Maier-Leibnitz Prize from DFG (German Research Foundation) and in 2020 awarded with Heisenberg-Professor Programme of DFG.

The status of the IEEE-NMDC Conferences impacted by the COVID-19 pandemic:

  • IEEE NMDC 2020 originally planned in Nanjing, China became a virtual symposium on October 26-27; the organizers will now host  NMDC 2022 on October 16-19, 2022, still in Nanjing.
  • IEEE NMDC 2021, colocated with CEIDP 2021, is planned to be held at the Pinnacle Harbourfront Hotel, Oct. 17-20, 2021, Vancouver, Canada.

Please note that due to COVID-19, we may face uncertainty related to travel options and restrictions as well as economic impacts. While we have planned for a face-to-face meeting, we are prepared to take contingency steps that include provisions for remote participation and attendance. Updates will be provided at the IEEE NMDC 2021 website.

  • IEEE NMDC 2023 will be held in Italy.

Solicitation of hosting proposals is open for IEEE NMDC 2024.

April 16th, 2021

The submission deadline for Short Abstracts has been extended to May 15, 2021.

See Call for Papers page for details.

Prospective authors are invited to submit high quality papers reporting original results under the broad theme, and in all areas of nanotechnology materials and devices Best Conference Papers and Best Student Papers will be awarded Information for Authors including Submission Instructions and requirements can be found on these pages.

16th IEEE Nanotechnology Materials and Devices Conference (IEEE NMDC 2021) Call for Papers

IEEE NMDC 2021 sponsored by IEEE Nanotechnology Council (NTC) will be held in the Pinnacle Harbourfront Hotel located in the center of Vancouver, BC, Canada from October 17th to 20th, 2021. The conference will be co-located with another conference – IEEE CEIDP (Conference on Electrical Insulation and Dielectric Phenomena) sponsored by IEEE Dielectrics and Electrical Insulation Society (DEIS).

IEEE NMDC is a well-received international conference and has been held annually rotating in different parts of the world, having the last two editions in Stockholm, Sweden in 2019 and Virtually (due to COVID-19 restrictions) in 2020. IEEE NMDC aims to highlight current work and future directions in nanotechnology-related research in the areas of nanomaterials and fabrications, nanoelectronics, nano-energy, packaging, nanophotonics, bioengineering, modeling and simulation, devices, and integration. This conference brings together key researchers from every sector in the nanotechnology research field, with a special focus on materials and devices.


The technical program for NMDC 2021 provides a wide variety of topics that emphasize the role of nanoscale phenomena, materials and devices in established and emerging technological areas. Before submitting abstracts, researchers are encouraged to examine the Technical Program Areas to identify the ones that most closely reflect the emphasis of their work.
