Several biomimetic artificial muscles including the electro-active synthetic polymers (SSEBS, PSMI/PVDF, SPEEK/PVDF, SPSE, XSPSE, PVA/SPTES and SPEI), bio-polymers (Bacterial Cellulose and Cellulose Acetate) and nano-composite (SSEBS-CNF, SSEBS-C<SUB>60</SUB>, Nafion-C<SUB>60</SUB> and PHF-SPEI) actuators are introduced in this paper. Also, some applications of the developed biomimetic actuators are explained including biomimetic robots and biomedical active devices. Present results show that the developed electro-active polymer actuators with high-performance bending actuation can be promising smart materials applicable to diverse applications.

Recently, agriculture in Korea is experiencing difficulties such as a shortage of rural manpower, an aging population, and a decrease in the proportion of production, As an alternative, smart farming methods that converge advanced technologies such as ICT and biotechnology have developed and are being reflected in rural areas. Among them, smart farming method incorporating ICT is emerging as an alternative that can directly improve efficiency in increasing the quality and production of crops. And also smart farm that can significantly reduce the need for manpower by automating the opening and closing of environmental information and cultivation facilities, and wild animal damage prevention system that generates specific patterns of light and sound by applying AI technology to harmful wildlife, etc. IoT convergence agricultural facilities are being actively developed. However, rural areas are often located in remote areas where information and communication are not well established or established, which often makes the use of high-tech IoT agricultural equipment impossible. Therefore, in this paper, we intend to present a method for efficiently designing IoT networks in rural areas by designing, reflecting, and verifying the network of agricultural IoT facilities in rural areas.
