Abstract: A semi-automatic corrosion box of a copper clad laminate is disclosed. The corrosion device comprises a box body which has no cover; a baffle plate which divides the corrosion box into an upper part and a lower part, wherein a copper clad laminate circuit board is placed on the baffle plate, and a temperature detection module, water pumps and a heating rod are placed on a lower part; and a thermal imaging camera which is placed on a pressing plate through a bracket. Modules in corrosive liquid are connected with an external single chip microcomputer control module through corrosion-resistant wires. The working mode of the present invention is that time and temperature are set with a key matrix at first, and the control module can automatically stop working and enter a low power consumption mode.

Abstract: A tubular friction nanogenerator and a cloth and an energy shoe including the same are provided. The tubular friction nanogenerator includes: a tubular friction layer, the friction layer being made of elastic material; an outer electrode layer covering an outer side of the tubular friction layer; an inner electrode layer having an outer surface, a portion or whole of which is attached to an inner surface of the friction layer, wherein in response to the tubular friction nanogenerator being restored after deformation, at least a portion of the inner electrode layer contacts and then is separated from an inner surface of the friction layer, so that a charge flow is generated between the inner electrode layer and the outer electrode layer.
