| Abstract |
A bending actuator using zigzag type shape memory alloy springs has been fabricated and characterized. The fabricated millimeter-sized actuator has outer diameter of 3.0mm and inner diameter of 2.0mm. The zigzag type spring is more suitable for thin wall type actuator because the zigzag type spring has a planar structure comparing with the coil type spring which has a three-dimensional structure. The measured characteristics of the fabricated bending actuator show the possibility of practical application to micro active bending catheters. |
