Toward Flexible and Wearable Embroidered Supercapacitors from Cobalt Phosphides-Decorated Conductive Fibers

Wearable supercapacitors(SCs)are gaining prominence as portable energy storage devices.To develop high-performance wearable SCs,the significant relationship among material,structure,and performance inspired us with a delicate design of the highly wearable embroidered supercapacitors made from the conductive fibers composited.By rendering the conductive interdigitally patterned embroidery as both the current collector and skeleton for the SCs,the novel pseudocapacitive material cobalt phosphides were then successfully electrodeposited,forming the first flexible and wearable in-plane embroidery SCs.The electrochemical measurements manifested that the highest specific capacitance was nearly 156.6 mF cm?2(65.72 F g?1)at the current density of 0.6 mA cm?2(0.25 A g?1),with a high energy density of 0.013 mWh cm?2(5.55 Wh kg?1)at a power density of 0.24 mW cm?2(100 W kg?1).As a demonstration,a monogrammed pattern was ingeniously designed and embroidered on the laboratory gown as the wearable in-plane SCs,which showed both decent electrochemical performance and excellent flexibility.

The phenomenon of the ＂variants of the same tune＂ of the Shanxi folk songs and its cultural interpretation

The ＂variants of the same tune＂ is the unique musical phenomenon produced in the process of the communication of the Chinese folk songs. A piece of the folk song, in the process of spreading to the different regions, will be constantly changing and creating a number of the variants of the folk songs, and these songs ＂with changes in the similarities＂ together constitute the songs of the ＂variants of the same tune＂. However, what musical elements are ＂the same＂ in the songs of the ＂variants of the same tune＂？ What musical elements have been changed？ What are the reasons for the ＂similarities＂ and the ＂changes＂？ These are the questions worth considering. To answer these questions, it is necessary to deeply explore the aesthetic and cultural psychologies of the folk groups in the areas of the spread of the folk songs. Therefore, this paper will select the typical folk songs of the ＂variants of the same tune＂ of＂For friends＂, ＂Hitting the wild jujube＂, and ＂Pouch Embroidering＂ in the Shanxi area as an example to carry out the analysis of the music and art and sort out the evolutionary tracks, and point out the feasibility to reveal the regional people＇s aesthetic and cultural psychologies with the help of the research on the folk songs of the ＂variants of the same tune＂ and the potential significance in the promotion of the creation of the current national folk music.

Effect of Process Parameters on S-Parameter of Fabric-Based Embroidered Transmission Line

This paper presented a method of fabricating radio frequency( RF) transmission lines by embroidering conductive thread on fabric. A digital embroidery machine was selected to fabricate transmission lines. Effects of the typical process parameters on the S-parameter of these RF transmission lines were tested and discussed. And the results showed that embroidery process parameters such as stitch direction,stitch spacing,stitch length and embroidered tension had significant effects on the RF performance of embroidered transmission lines,of which stitch type was the most important factor for the measured S-parameter of transmission lines.

Italian Textile Industry: Throw an Embroidered Ball in the Chinese Market

Throwing an embroidered ball is an act of seeking marriage practiced by noble family maidens in ancient China. March 2009, the early spring of Beijing saw Italian textile industry's passion for a close relationship with the Chinese market after a global shiver in the freezing economic winter. It is a ball of elegance, quality and sincere cooperation, which is to become larger and more attractive with the stable development of Chinese textile industry and the ever expansion of Chinese consumption market.
