Symposium NM09—Nanogenerators and Piezotronics

Recent advances in nanogenerator research demonstrated their feasibility and great potential in harvesting various types of energy from the environment, leading to novel power sources that operate over a broad range of conditions for extended time periods with high reliability and independence. During the past decade, the nanogenerator technology by using triboelectric, piezoelectric and other mechanisms has experienced a gigantic development. The integration of nanogenerators, energy storage units and functional devices has led to the implementation of various types of micro/nano-systems for implantable electronics, remote and mobile environmental sensors, nano-robotics, intelligent MEMS/NEMS, portable/wearable personal electronics and blue energy technology. The long-overlooked coupling between piezoelectric polarization and semiconductor properties in piezoelectric semiconductors, results in both novel fundamental phenomena and unprecedented device applications, and thus the rapidly rising research interests in the emerging fields of piezotronics and piezo-phototronics. These two processes enable technology advances in societal pervasive areas, e.g. sensing, human-machine interfacing, robotics, healthcare and more. This progress in the fields of piezotronics and piezo-phototronics, leads to compelling opportunities for research in materials science and broader areas, from basic studies of piezoelectricity and semiconductor properties in functional nanomaterials to the development of applications of “smarter” electronics and optoelectronics.

This symposium aims to advance fundamental understanding and technological development of mechanical energy conversion materials, devices and systems; as well as the coupling between piezoelectric polarization and semiconductor behaviors and functionalities. Abstracts on theoretical and experimental studies about topics listed below are particularly welcomed.

Topics will include:

  • Triboelectric, piezoelectric, flexoelectric and ferroelectric nanomaterials/nanostructures: synthesis, characterization, integration and material science
  • Novel designs and fabrications of triboelectric, piezoelectric, flexoelectric and ferroelectric nanogenerators for high-performance energy harvesting
  • Novel strategies in design, integration and power management of hybrid cells/nanogenerators for concurrently harvesting multitype energies
  • Self-charging power cell and Self-powered system design, integration and application
  • Tribotronics for electronics and sensors
  • Mechanism and characteristics of triboelectric and discharge effects
  • Piezotronics and Piezophototronics in 1D/2D nanomaterials for smart adaptive electronics and optoelectronics
  • Fundamental study on material science, band structure and interface engineering in piezotronics and piezophototronics
  • Novel approaches in integration and nanomanufacturing of piezotronic and piezophototronic devices
  • Fundamental and technological issues in piezocatalysis: catalytic properties modulated by piezoelectric or ferroelectric polarization
  • A tutorial complementing this symposium is tentatively planned.
