Abstract

The creation of fully integrated ZnO 1D nanostructure-based piezoelectric charge-generating devices suitable for use as transparent, flexible (TF) self-powered pressure sensors, which are driven by mechanical forces without any electrical sources, was studied. ZnO nanorods on a flexible plastic substrate were prepared using an aqueous solution method. Zinc acetate dehydrate was dissolved in ethanol that had been heated at 90°C. The seed solution was dropped onto the substrate and spin coated at 1000 rpm for 60s. The spin-coated substrate covered with a ZnO-seed layer, was dried onto a hot template at 100°C. FE SEM was performed and HRTEM was carried out using a JEOL 2010F TEM (field emission) with an accelerating voltage of 200 kV. A TF piezoelectric nanodevice with ITO/PES top electrode gave a current density of δ1μA cm^-2 which is sufficient for use as a force/pressure sensor.
