Abstract: A wireless transmission module for transmitting energy or signals includes a first magnetically conductive element, a first coil assembly and a first adhesive element. The first coil assembly and the first magnetically conductive element are arranged along a main axis. The first adhesive element is configured to be adhered to the first coil assembly and the first magnetic conductive element. The first adhesive element is disposed between the first coil assembly and the first magnetically conductive element.

Abstract: A method for preparing a composite matrix containing chitosan derivatives, comprising the steps of: (a) providing an anionic chitosan derivative solution (A); (b) providing a cationic polysaccharide solution (B); and (c) mixing solution (A) and solution (B) to form microcapsules. Metallic ion cross-linking agent and/or natural protein solution can be added optionally to adjust the mechanical strength of the shell and the interior physic state of the microcapsules.

Abstract: The present invention relates to a biodegradable thermal-sensitive gel system, which comprises at least one polysaccharide solution, at least one electrolytic salt, and at least one buffer solution for adjusting pH. A natural protein as well as a cross-linking agent can be added to the gel system optionally. Said gel system is liquid at room temperature (25° C.) and solidifies at or above 37° C.

Abstract: A biodegradable composite matrix for enhancing angiogenesis. The matrix includes a biodegradable material and a phospholipid distributed in the biodegradable material as a liposome or micelle. Derivatives of phospholipid have chemo-attraction properties and thus induce the transfer of endothelial cells into the system through tropism-inductive mechanism. The biodegradable composite matrix induces an intracellular signal cascade that is different from cascade induced by a growth factor, and can coordinate with the growth factor-induced cascade to enhance angiogenesis. The present invention also includes the method for producing the biodegradable composite matrix.
