Abstract
A simple, portable DC voltage standard has been developed, using poled PZT (lead zirconate titanate) with the application of a charge recovery process. The charge decay is due to compensating charges coming to the PZT surfaces from the atmosphere and/or by electrical loading of the PZT, and these charges screen the intrinsic PZT charge. The maximum open circuit voltage of the PZT has been recovered and measured with an accuracy of ±10 μV. It was also confirmed that the PZT DC voltage source remained constant at different places
