This paper aims to present a modular multimodal flexible electronic skin that can be used for robot collision detection in human–robot interactions. This type of electronic skin will meet the requirements of performance indicators such as sensing mode, sensing domain coverage and dynamic data update rate in human–robot interactions.

The electronic skin uses a modular architecture, and the sensing module is designed to be adjustable in size so that it can be easily deployed on complex robot surfaces, increasing area coverage, reducing power consumption, and improving data update rates.

The authors evaluated electronic skin through experiments using a UR5 robot. Electronic skin has high static scene perception differentiation and dynamic scene perception abilities. Moreover, the robot realizes a high-speed collision response based on the electronic skin proposed in this study.

The proposed electronic skin provides crucial technical support for advancing robotic technologies, and holds promising prospects for industrial applications.

The purpose of this paper is to describe green technological trajectories in eco‐industrial parks and reveal the effect of the selected environment on the trajectories in China, by means of case studies of the Lubei Group and the Guitang Group.

The paper opted for content analysis from various sources, including annual reports of listed companies, newspapers, web sites and academic articles. It adopts contrast analysis, in order to show the different technological evolution trend and the diversified dynamics of the selected environment.

The study provides the empirical insights about how green technology evolves and affects the evolution of the eco‐industrial park. The green technology development of the Lubei Group forms self‐reinforcing mechanism through learning process, economies of scale in production and network externalities, while that of the Guitang Group is under way. Additionally, the paper discusses how the selected environment affects the green technology, referring to the six factors constituting the selected environment: environmental regulation, financial support, knowledge accumulation, market environment, organizational culture and resource endowment.

The paper analyzes the evolution process, drivers and operational risks of eco‐industrial parks in the perspective of green technological trajectories. Some practical suggestions, such as eco‐industrial parks should put the focus on environmental intellectual property protection, green core competencies construction and green technology transfer strategies are proposed. What is more, the Lubei Group is a large, state‐owned enterprise and the Guitang Group used to be. The contrast analysis tends to disclose the context‐embedded knowledge of eco‐industrial parks development in an emerging market.

Purpose is to design the energy harvesters and to know the limit of the application of load on the PZT material. Fatigue failures of the designed products is merely bothering the modern engineers and scientists for the research communities of all fields. Especially in the field of Micro Electromechanical Systems (MEMS), durability of low power systems is very important under the climates of both at high temperature and low temperature zones. And also continuous electrical power requirement is important for the MEMS and wireless sensor networks. Electricity is the greatest crisis in the world on one side and on the other side, durability of smart devices such as mobile phones, laptops, compact devices, computer spare parts are unrecyclicable batteries for reducing the rate of pollution in the environment.

By considering these problems, authors have taken up a research in finding the first fatigue characteristics, which are fatigue failure and durability of ferroelectric material as lead zirconate titanate, and then designed the scavenging device by using harmonically excited vibrations for getting optimum power output which is about 15.6 mW.

Under the resonance operated condition at the frequency of about 50 Hz, a prototype of scavenging device is about 90 V AC peak-to-peak voltage and the durability of scavenging device is 9.715 years.

Durability of PZT at different environmental conditions plays a very important role for the continuous function of low power devices. The output of PZT may change when the working time increases in addition with the mechanical properties.

Social information is crucial to credit ratings and can improve the accuracy of the traditional credit assessment model. Drawing on the resource-based view (RBV) and social capital theory (SCT), this research explores the relationships between corporate social activities, network centrality and corporate credit behavior.

The authors used social network analysis (SNA) and regression analysis to analyze the data collected from 14,544 enterprises on the Alibaba platform.

The results indicate that among the four types of social activities, the number of corporate questions and posts shows a positive relationship with credit behavior; while the number of corporate comments has negative relationship with credit behavior. Further, degree and betweenness centralities mediate the relationship between the number of corporate questions, posts and comments with credit behavior.

This study contributes to the literature on non-financial factors (soft information) by exploring the social behavioral factors related to corporate credit. In addition, this study offers a new theoretical lens and reasonable explanations for investigating the relationship between corporate social activities, network centrality and credit behavior from the perspective of the resource-based view, while most studies are predictive and methodological. Moreover, this study provides new insights for platforms to evaluate enterprise credit and for managers to improve credit behavior.
