This project aims to create a novel bilayer ferroelectric material structure that provides giant electromechanical response at the nano-scale. Traditional electromechanical devices based on ferroelectric materials including position sensors, mechanical actuators, and ultrasonic transducers rely on bulk form. As technology moves toward integrated functionalities, future electro-mechanical materials need to be scaled down to thin film form. Currently, doing this induces mechanical constraints that dramatically suppress the electromechanical response. Using this approach one layer relieves this mechanical constraint while the other gives a giant electromechanical response, providing a pathway for future functional devices.

该项目旨在创造一种新型的双层铁电材料结构，在纳米尺度上提供巨大的机电响应。 传统的基于铁电材料的机电设备，包括位置传感器、机械致动器和超声换能器，都依赖于块状形式。随着技术向集成功能发展，未来的机电材料需要缩小到薄膜形式。目前，这样做会引起机械约束，大大抑制机电响应。使用这种方法，一层解除了这种机械约束，而另一层则提供了巨大的机电响应，为未来的功能设备提供了一条途径。
