    Abstract: Improving the efficiency of vibration power generation is an important research topic. Therefore, it is effective to develop a vibration power generation system using a bistable vibration model. The bistable vibration model considered in previous studies has the problem that the center of gravity is high and the vibration power generation efficienc... Show More

    Abstract: We have developed many types of transport boxes by origami-operation and space filling operation. But it has not been solved that the fruits, vegetables, strawberries, cells, blood and a bottle of liquor are damaged, broken during transportation. It is the greatest factor in this situation that there is a danger vibration frequency band where these... Show More

    Abstract: Producing industrial goods with origami structure, such as cans or bottles which can be folded neatly after drinking up, is an idea anyone could easily think of. However, this idea has not been put in practical use yet. Recently, Tachi-Miura polyhedron (TMP) is gaining attention as a 3-dimensional version of Miura-Ori. Meanwhile, Nojima Polyhedron ...
