AB  - The paper reports the design and fabrication of amicro-planar spring for a dynamic regulating mechanismto decrease the cut-in (start-up) airflow speed of apiezoelectric turbine. This mechanism is implemented byadjusting the magnetic coupling between the turbine rotorand a piezoelectric cantilever using the spring. Variedspring shapes and dimensions were analyzed with the finiteelement method (FEM) to optimize the structure. A microspring with an ultra-low spring constant of 0.78 N/m wasfabricated from titanium foil by laser machining. Thespring was installed into a miniaturized air turbine toachieve the self-regulation. The cut-in speed was 2.34 m/s,showing a 30% improvement against a non-regulatedturbine.
