Wearable sensors with highly flexible and sensitive characteristics have attracted research interests in the promising field of electronic skin, health monitoring, and soft robotics. However, the developing of high-performance piezoresistive sensor is full of challenges due to the expensive equipment and complex procedures. Herein, we fabricate a reduced graphene oxide/ polyurethane composite sponge (GPCS) pressure sensor combining with dual-templates. The polyurethane (PU) sponge provides an elastic structure as solid template. Meanwhile, air bubbles as gas template are used to uniformly disperse graphene oxide (GO) sheets. The burst of air bubbles in the process of thermal treatment makes GO coating on the surface of PU skeleton, avoiding the aggregation of reduced graphene oxide. Therefore, the GPCS exhibits excellent compressibility and uniform coating structure. As a result, it also possesses high sensitivity (Gauge Factor = 3.00 in the range of 0–10% strain), fast response time (35 ms), and excellent cyclic piezoresistive stability (5000 loading–unloading cycles) when applied in the pressure sensor field. Moreover, the flexible wearable stress–strain sensor assembled by the GPCS can be easily adhered on the surface of human skin and precisely detect human movements such as elbow bending and finger bending. Such low-cost procedure and excellent sensing performance enable GPCS sensor to demonstrate tremendous application potential in the field of advanced wearable devices.

As the number of SNS(Weibo) users in China is growing rapidly, Chinese fashion brands are heavily dependent on SNSs as a fashion marketing communication tool. For this reason, the characteristics of SNS accounts and their influences on SNS users’ responses need to be studied. Thus, the present study aimed to investigate the influences of the characteristics of Chinese fashion brands’ SNS accounts(Weibo) on the perceived usefulness of and satisfaction with the SNS acount, and brand loyalty. Data were collected via a questionnaire survey of men and women living in Beijing or Shanghai aged from 18 to 49 with experience of SNSs(Weibo). After a pilot survey of 70 subjects, the preliminary questionnaire was revised and then translated into Chinese. The questionnaire translated into Chinese was back-translated into Korean to ensure the translation was correct. The final questionnaire was administered to 600 subjects. Exploratory and confirmatory factor analyses, reliability analysis, and structural equation model analysis were conducted for data analysis. The results of this study were as follows: Five factors were extracted for Weibo characteristics: interaction, information provision, information recency, information reliability, and information playfulness. The information reliability, information playfulness, and interaction of SNS accounts(Weibo) had significant influences on perceived usefulness. The information playfulness, information reliability, and information recency showed significant influences on satisfaction. The perceived usefulness exerted significant influences on satisfaction and brand loyalty. The satisfaction also had statistically significant influences on brand loyalty.
