A team of engineers from the Chinese University of Tsinhua designed a passive energy generation system using the natural movements of a person carrying a heavy backpack. Separately, it is emphasized that the device does not use the muscle power of the carrier, does not require any effort from it, except for the very fact of movement. So far this is an experimental technology, the prototype has not yet passed the test.

The idea is not new – if you hang a cargo on the thread, then you can use the swing and inertia of its oscillations. To make the system practical, it is necessary to install guides that will limit movements in one plane, and connect a triboelectric nanogenrator to convert the energy of movement into electricity. In the case of the new Chinese development, the return of cargo to the top occurs due to the reduction of elastic slings on which it is suspended.

The authors of the development say that the system reduces vertical fluctuations in the cargo by 28.75 %, which leads to a decrease in the load on the user by 21.08 %. The cargo in the generator fluctuates in its rhythm, it does not coincide with the steps of a person and does not depend on the efforts made by him. To maintain the balance and ease of use of the backpack, the system was minimized and left the efficiency at the level of only 14 %. However, if you go with such a backpack all day, it will be able to charge the battery of a flashlight or smartphone to use them in the evening.
