Latest Patents

One of Guanggui Cheng's latest patents is an energy harvesting and self-cleaning system based on graphene aerogels and its preparation method. This invention involves sputtering a layer of metal collector on both sides of freeze-dried graphene aerogel using magnetron sputtering. The graphene aerogel with the collector is then fixed on the side and bottom of a substrate in series and/or parallel connection, followed by immersion in an electrolyte to create the target system. This system not only provides a novel approach to mechanical energy harvesting but also plays a role in ocean cleaning by absorbing oil and other impurities. The energy collection system formed by a single aerogel can produce approximately 220 mV open circuit voltage in Sodium Chloride Solution or organic electrolyte, generating a power density of 2 W/kg.

Another significant patent is a continuous automatic twisting and winding device and method for polymer fiber artificial muscles. This device includes a wire feeding mechanism, polymer fibers, a twisting mechanism, a winding mechanism, a translation mechanism, and a base plate. The design ensures that the center axis of the rolling bearing in the wire feeding mechanism aligns horizontally with the center axis of the spline shaft in the winding mechanism. The polymer fibers used are typically nylon or polyester, and the mechanisms are mounted on a base plate for efficient operation.
