Abstract: The present invention provides new impact protection materials and the method of making the same. More specifically, the impact protection materials are polymer-based shear-thickening composite comprising a non-shear-thickening polymer matrix material and one or more shear-thickening materials. Preferably, the non-shear-thickening polymer matrix material is in an amount from approximately 5 weight percent to approximately 90 weight percent with the balance being one or more shear-thickening materials. The first type of the one or more shear-thickening materials is sol-gel based shear-thickening material in which small inorganic particles are connected in a gel network; the second type is polymer-based shear-thickening material in which polymer chains form network. Compared to the existing shear-thickening materials, the present shear-thickening materials have different molecular structure and formulation and possess properties of good impact protection and good stability.

Abstract: The present disclosure provides a flexible electric generator and methods for fabricating the same. The flexible electric generator comprises a flexible triboelectric layer covering the electrode layer of a flexible piezoelectric generator that enhances output power by combining piezoelectric effect and triboelectric effect. The reliability of the flexible electric generator under bending is also improved due to the presence of the flexible triboelectric layer. The fabrication methods of the disclosed flexible electric generators are simple, thereby enabling large-scale manufacturing.
