Abstract
Piezoelectric actuators are provided. In some instances, the piezoelectric actuators are high-precision piezoelectric actuators. The piezoelectric beams may have a bi-chevron configuration. Also provided are methods of making the piezoelectric actuators, e.g., using Micro-Electro-Mechanical System (MEMS) fabrication techniques, and methods of using the piezoelectric actuators, e.g., as valves in fluid dispensing systems.
