Smart Structures via 4D printing of Hydrogel Materials

Hydrogel actuators with soft-robotic capabilities and biomimetic advanced materials with simple and programmable fabrication processes are still in scarce. We describe a novel method for constructing a shape-memory-hydrogel-based bilayer system via 3D printing, resulting in a soft actuator that responds to methodical application of swelling and heat. Additionally,

4D printed systems based on single inter-crosslinking hydrogel materials have also been studied to comprehend the deformation mechanism of 4D printed structures by selecting printing parameters e.g. suitable scan number or total UV light irradiation time via stereolithography printing technique. These 4D-printed systems will be demonstrated to imitate living organisms that exhibit multi-directional actuation.

A presentation by MD Nahin Islam Shiblee , Assistant Professor at Yamagata University, Japan.

About MD Nahin Islam Shiblee
MD Nahin Islam Shiblee graduated with a bachelor’s degree from the Department of Chemistry, University of Dhaka, Bangladesh in 2012 and received M.Sc. in 2014. He received D.Eng. degree in 2019 from Department of Mechanical Systems Engineering, Yamagata University. During his doctoral course, He was appointed as a researcher in the project named Open Innovation Platform with Enterprises, Research Institute and Academia (OPERA) funded by Japan Science and Technology Agency (JST).

After completing the doctoral degree, He joined as a Post-doctoral researcher in Yamagata University in October 2019 and in April 2020, He joined as a researcher in Miraikan-National Museum of Emerging Science and Innovation (Yamagata University project). In June 2020, He was appointed as an Assistant Professor in the Graduate School of Science and Engineering of Yamagata University. His research interest involves the field of soft materials, 3D/4D printing and soft robotics.

About Yamagata University
As one of the best national comprehensive universities in northern Japan, Yamagata University fosters human resources who can solve the problems and innovate new technologies for local and global societies. Offering the variety of courses, we are dedicated to create high-quality environments that meet their learning needs and interests.

History and Tradition
Yamagata University has produced many distinguished graduates, carrying on the tradition treasured since back in the time of the five predecessor schools.

Yamagata University has four campuses spread throughout Yamagata Prefecture. By networking and enhancing collaboration among these campuses, YU offers educational programs and research projects making full use of each region’s characteristics.

  • Kojirakawa Campus (Yamagata City) – Humanities and Social Sciences/Education, Art and Science/Science/Department of Architecture and Design, Faculty of Engineering
  • Iida Campus (Yamagata City) – Medicine
  • Yonezawa Campus (Yonezawa City) – Engineering
  • Tsuruoka Campus (Tsuruoka City) – Agriculture

Commitment to General Education
YU named its general education programs as “Arts and Sciences Education” (Kiban Kyoiku in Japanese) in 2010. The purpose of Arts and Sciences Education at YU is to have students expand their views, think critically and make sound judgments in the rapidly changing society, as well as to acquire the fundamental academic skills necessary for advanced study.
Faculties at YU teach students the well-selected themes of their own specialties, using the various teaching methods. Students can acquire the basic and necessary skills needed to succeed in their future careers through small-sized seminars, information-processing education and practical language education.
As a comprehensive university, YU proudly offers students the wide variety of Arts and Sciences Education curriculums to choose freely. Student evaluation for each class is conducted, and both faculties and students make continuous efforts to improve the quality of classes.

Rich Natural Environment
Yamagata is surely one of the greatest places in Japan to experience the beauty of four distinct seasons. Throughout the year, there are various fieldworks to join in the rich natural environment of Yamagata. Students enjoy their campus life each and every season: Seeing cherry blossoms and hiking in the fresh green of the mountains in spring, fishing and marine sports in the Sea of Japan in summer, beautiful foliage and delicious “Imoni-kai” (taro and beef stew party) in autumn, and skiing, snowboarding and other winter sports in winter.
