We present small-size, low-power, and high-speed electromagnetic flapping shutters composed of trapezoidal twin blades suspended by H-type torsional springs for phone camera applications. The previous electrostatic rolling and flapping shutters need high input voltage, while the previous electromagnetic rotating shutters are too large to use in phone cameras. For low-power and high-speed angle motion...
We present the small-size, low-power, and high-speed electromagnetic flapping shutters, composed of the butterfly-wing shaped twin blades suspended by H-type torsional springs for phone camera applications. The present electromagnetic flapping shutters are designed to use the low-inertia trapezoidal twin blades, each suspended by the low-stiffness H-type torsional springs. In the experimental study,...
