The fabricated C&C IC measures 1.0 mm×3.35 mm×0.2 mm. The outer diameter of the fabricated active catheter is approximately 2.0 mm. To reduce system size and simplify assembly work, the C&C circuit and three lead wires are fabricated on the same substrate using a CMOS-compatible polyimide-based process. A MOS transistor with large channel width is used for switching the SMA actuator. The C&C ICs are incorporated within the links and require three common lead wires to address all the links and control the selected SMA actuators in the active catheter. The active catheter has a multi-link structure and distributed micro Shape Memory Alloy (SMA) coils are utilized as actuators for multi-degree of freedom movement. The active catheter was actuated by the fabricated C&C IC chip with flexible interconnect leads in response to the C&C signals from the outside controller.Ībstract = 'This paper describes an active catheter with flexible polyimide-based integrated CMOS interface circuits for communication and control (C&C IC) to be used for applications in biomedicine. The minimum access time for addressing and actuating a single unit was 6.4 μs. The link addressing and the actuator switching functions of the fabricated chip were confirmed.
