Development of enhanced synthetic elastomer for energy-efficient polymer actuators
Jung, Kwangmok,Lee, Joonho,Cho, Misuk,Koo, Ja Choon,Nam, Jae-do,Lee, Youngkwan,Choi, Hyouk Ryeol Institute of Physics Publishing 2007 Smart materials & structures Vol.16 No.2
<P>In this paper, a new material, called a synthetic elastomer, is presented as a means of actuation. The material displays enhanced performances in terms of electrical as well as mechanical aspects such as dielectric constant, elastic strength and stress relaxation. We begin by developing synthesis procedures for the material, which result in its general recipe with chemical composition. In addition, the effects of respective chemical constituents are studied with regard to the electrical and mechanical characteristics of the actuator. Finally, experimental tests are performed to evaluate the actuation performance of the material, and its advantages are clarified by conducting comparative studies with other existing materials.</P>
Biomimetic soft actuator: design, modeling, control, and applications
Choi, Hyouk Ryeol,Jung, Kwangmok,Ryew, S.,Nam, Jae-Do,Jeon, Jaewook,Koo, Ja Choon,Tanie, K. IEEE 2005 IEEE/ASME transactions on mechatronics Vol.10 No.5
A new biomimetic linear actuator named Antagonistically Driven Linear Actuator (ANTLA) that could be directly employed in both macro and microscale of robotic applications is introduced in the present work. The presented actuator provides cost effectiveness and simple fabrication process thanks to its plain construction. In addition to producing basic bidirectional rectilinear motions, the actuator is able to modulate its compliance that might be one of the critical elements of the actuator functionality for the biomimetic applications. For the test, the proposed actuator concept is fabricated and assembled in a microscale robot that generates annelid motion.
