Abstract: A self-powered sensing and transmitting device is provided and includes a piezoelectric generator, a carrying structure stacked with the piezoelectric generator, an encapsulation support structure including an encapsulation portion encapsulating the piezoelectric generator and the carrying structure and two supporting portions connected to two ends of the encapsulation portion, and a fixed support structure for being correspondingly coupled with the two supporting portions and fixed on a flexible surface. The self-powered sensing and transmitting device can be applied to a tire monitoring system and a motion monitoring system.

Abstract: An aqueous polyurethane dispersion and a textile are provided. The aqueous polyurethane dispersion includes water and a bio-based polyurethane. The bio-based polyurethane includes bio-based polyester polyol, hydrophilic polyol, isocyanate, and hydrophilic compound. A weight ratio of the bio-based polyester polyol to the hydrophilic polyol is 2.7:1 to 5.3:1.

Abstract: A method for decolorization of polyester fabrics is provided. The method for decolorization of polyester fabrics includes putting polyester fabrics into an extraction cell. The method for decolorization of polyester fabrics also includes making a supercritical fluid and a co-solvent flow into the extraction cell. The method for decolorization of polyester fabrics further includes adjusting the temperature in the extraction cell to be greater than or equal to the glass transition temperature of the polyester fabrics, so that the supercritical fluid and the co-solvent perform a decolorization reaction on the polyester fabrics. Moreover, the method for decolorization of polyester fabrics includes making the supercritical fluid and the co-solvent flow out of the extraction cell. The method for decolorization of polyester fabrics also includes taking the polyester fabrics out of the extraction cell.
