Yu, Min-Feng Wang, Zhaoyu 2015-09-25T21:12:41Z 2015-09-25T21:12:41Z 10000-01-01 2008 2008 With the assistance of nanomanipulation and electron beam deposition techniques, a nanoscale energy converter device was fabricated using an individual BaTiO3 nanowire. In this device, due to the piezoelectric effect, voltage response was generated from the BaTiO3 nanowire by a periodically varying tensile mechanical strain applied with a precision mechanical testing stage. The measured voltage generation from the nanowire was found to be directly proportional to the applied strain rate, and was successfully modeled through consideration of an equivalent circuit for the piezoelectric nanowire under low frequency operation. This device, besides demonstrating a controlled experimental method for the study of direct piezoelectric effect in nanostructures, also implies the use of such perovskite piezoelectric nanowires for efficient energy harvesting applications.
