This backpack is designed having moving structure and fixed structure (i.e., conventional structure). Bag and load are installed with moving structure, which is motioned in vertical or bearing guideline. It is relation to the movement of users. The spring is used for generating motion of bag load by using Hooke's law and spring properties. It can be stretched and shrunk to change the form and size of spring in vertical. The mechanism of this backpack will lead to generation of motion on bag load when users have activities assigned to walking or running. Fourthermore, it also studied the displacement at the reference position measurement by using a laser displacement sensor. Therefore, this study has an important role in new structure designing of backpacks for energy harvesting. It also applicable to other works for innovative backpack leading to globalized society in the future.
