piezoelectricity

Within the frame of the 8th ECCOMAS Thematic Conference on Smart Structures and Materials (SMART 2017), to be held in Madrid, Spain, on June 5-8, 2017, we are organizing minisymposium MS13 titled “Smart materials capable of recoverable inelastic strain”. 

Relevant contributions are solicited specifically in the following technical areas:

1. Modeling, simulation and experimental characterization of shape memory alloys, piezoelectric materials and their composites,

2. Investigation of degradation and failure mechanisms in smart materials,

We are seeking a motivated PhD student (only a student currently in the US for an immediate start) to work as a Graduate Research Assistant in our NSF project titled "Metamaterial-Enhanced Electroelastoacoustic Energy Harvesting for Sensor Systems." This computational and experimental project will investigate electroelastoacoustically coupled linear and nonlinear metamaterial-inspired piezoelectric energy harvesting concepts for self-powered sensor systems.

A review article of our research at IBM TJ Wason Research Center in piezoelectronic transistor, an exploratory device beyond silicon, is published in MRS Bulletin, Volume 37, Issue 11, November 2012, pp 1071-1076. Your future computer may depend even more on the mechanics.

Abstract

A nanocomposite electrical generator composed of an array of zinc oxide nanowires is considered.
The electric potential distribution along zinc oxide nanowires is modeled using continuum
mechanics and Maxwell’s equations for the case of axial loading. A perturbation technique is used
for decoupling the constitutive equations. The governing differential equations are solved using a
finite difference method. It is shown that a gradient of electric potential exists along the axis of the
zinc oxide nanowires. Maximum and minimum values of electric potential exist at the extreme ends
along the nanowire length and have opposite signs. The positive and negative voltages are separated
