    초록 A wireless capsule endoscope, M2A, has been developed to replace the conventional endoscope. However, the commercialized capsule endoscope moves passively by peristaltic waves (and the gravity), which has some limitations for doctors to diagnose more thoroughly and actively. In order to solve this problem, a locomotive mechanism is proposed for wireless capsule endoscopes. Based on the tests of various actuators, a piezo actuator is selected as a micro actuator for capsule endoscope. Piezo actuators are known to have limited displacement with high voltage supply. In order to overcome the limitation of common Piezo actuator, the impact based piezo actuator, is developed to realize long stroke up 1 Imm. Moreover, clampers mimicked the claw of a insect are employed. A prototype of an earthworm-like locomotive mechanism with an impact based piezo actuator and engraved clainpers was developed. It has 15mm in diameter and 30mm under retraction stage and 41mm under elongation stage in total length. Hollow space is allocated to comprise essential endoscope components such as a camera, a communication module, bio sensors, and a battery. For the feasibility test of proposed locomotive mechanism, a series of experiments were carried out including in-vitro tests. Based on results of the experiments, we conclude that the proposed locomotive mechanism is effective to be used for micro capsule endoscopes.
