Study on Design and Fabrication of Micro-Pyrotechnical Actuator

Combustion of energetic materials is an attractive means of obtaining a large quantity of energy from a small volume. And these materials can be integrated into functional micro-systems in a manner compatible with micro-system technologies, then micro-pyrotechnics could help to make considerable progress in the field of micro-actuation . In this paper,a micro-pyrotechnical actuator was designed and fabricated. Detailed design and fabrication process of each part of actuator were presented, and the integration is described. Its operation was validated by experimentation. The firing performance is excellent for low-energy ignition requirement.
