Piezoelectric actuators are made from a ceramic material that expands in response to an applied voltage. Although these actuators develop the greatest forces and most precise motion of any actuator, a number of performance limitations exist. This proposal aims to overcome these limitations and greatly increase the performance of piezoelectric actuators. Improved piezoelectric actuators will result in a parallel improvement of analytic and process machines throughout the scientific and industrial community. Examples include: improved atomic scale microscopes, finer tolerance steel rolling mills, more accurate micro-surgical tools, and automated manipulation of sperm and egg cells in IVF therapy.

压电致动器由响应于施加的电压而膨胀的陶瓷材料制成。尽管这些致动器产生任何致动器中最大的力和最精确的运动，但是存在许多性能限制。该建议旨在克服这些限制，并大大提高压电致动器的性能。 改进的压电致动器将导致整个科学和工业界的分析和处理机器的平行改进。示例包括：改进的原子尺度显微镜，更精细的公差轧钢米尔斯，更精确的显微手术工具，以及IVF治疗中精子和卵细胞的自动操作。
