Abstract
Flexible stacked type actuators have been developed. The typical flexible stacked type actuator is composed of 20 sheets of PZT unimorph cells. These cells are piled vis-a-vis, and these cells are connected with a flexible rod at the edge of each cell. The electrodes are connected to one another with copper wire 50 μm in diameter. The actuator is 12 mm in diameter and 6 mm in length. The bending angle is 8 degrees with no weight and 4.5 degrees with 100 g weight when electrodes on a cell are charged with 250 V driving voltage. The laser scanning system that contains two flexible stacked type actuators and a mirror at the top of the actuator is manufactured. The laser scanning system can draw simple diagramsKeywords
