Abstract
Purpose
Flexible pressure sensor arrays have promising applications in analog haptics, reconfiguration of sensory functions, artificial intelligence, wearable devices and human-computer interaction. The force disturbance generated by the connecting material between the sensor array units will reduce the detection accuracy of the unit. The purpose of this paper is to propose a flexible pressure sensor with interference immunity capability. A C-type bridge flexible piezoelectric structure is used to improve the pressure perturbation. The interference immunity capability of the sensor has been improved.
Design/methodology/approach
In this paper, a C-type pressure sensor array structure by rapid injection moulding is manufactured through the positive piezoelectric effect of a piezoelectric material. The feasibility of C-type interference immunity structure in a flexible sensor array is verified by further analysis and experiment. A flexible pressure sensor array with C-type interference immunity structure has been proposed.
Findings
In this paper, we present the results of the perturbation experiment results of the C-type pressure sensor array, showing that the perturbation error is less than 8%. The test of the flexible sensor array show that the sensor can identify the curved angle of up to 120 °, and the output sensitivity of the sensor in the horizontal state reaches 0.12 V/N, and the sensor can withstand the pressure of 80 N. The flexible sensor can work stably in the stretch rate range of 0–8.6% and the stretch length range of 0–6 mm.
Originality/value
In this paper, C-type pressure sensor array structure is fabricated by rapid injection moulding for the first time. The research in this paper can effectively reduce the disturbance of input pressure on the sensor’s internal array and improve the output accuracy. The sensor can intuitively reflect the number of fingers sliding on the sensor by the order in which the maximum voltage appears. Due to the strong interference immunity capability and flexibility of the flexible sensor array mechanism, it has a broad application prospect in the practical fields of haptic simulation, perceptual function reconstruction, artificial intelligence, wearable devices and human–computer interaction.

The purpose of this study is to provide a micro-nano chip automatic alignment system. Used for micron and nanometer channel alignment of microfluidic chip.
Abstract
Purpose
The purpose of this study is to provide a micro-nano chip automatic alignment system. Used for micron and nanometer channel alignment of microfluidic chip.
Design/methodology/approach
In this paper, combined with the reconstructed micro–nanoscale Hough transform theory, a “clamp–adsorb–rotate” chip alignment method is proposed. The designed alignment system includes a microscopic identification device, a clamping device and a suction device. After assembly, the straightness of the linear slide rail in the horizontal and vertical directions was tested, respectively. The results show that in the horizontal and vertical directions, the linearity error of the linear slide is +0.29 and 0.30 µm, respectively, which meets the requirement of chip alignment accuracy of 15 µm. In the direction of rotation, the angular error between the microchannel and the nanochannel is ±0.5°. In addition, an alignment flow experiment of the chip is designed. The results demonstrate that the closer the angle between the microchannel and the nanochannel is to 90°, the fluid fills the entire channel. Compared with the conventional method, the method and the assembly system realize fully automatic double-layer chip alignment.
Findings
A mechanical device designed by Hough transform theory can realize microfluidic chip alignment at nanometer and micron level.
Originality/value
The automatic alignment device adopts Hough transform principle and can be used for microfluidic chip alignment.

This paper aims to study individuals’ information service satisfaction during the COVID-19 pandemic lockdown in China’s urban communities.
Abstract
Purpose
This paper aims to study individuals’ information service satisfaction during the COVID-19 pandemic lockdown in China’s urban communities.
Design/methodology/approach
The researchers analyse people’s uncertainties during the pandemic and argue that uncertainties caused by the lockdown can negatively affect people. By reducing people’s uncertainty during the pandemic, community staff members can improve individuals’ information service satisfaction and social order. This study constructs a conceptual model that includes key transparency and self-disclosure constructs and their relationships that can contribute to the trust and satisfaction of the community information service phenomenon. The researchers collected 489 responses to test their hypothesis from an online survey of Chinese residents in areas where the strict lockdown policy was implemented.
Findings
The empirical results show that policy and goods information transparency significantly affect information service satisfaction in a positive way, with goods information transparency having the highest impact. Second, self-disclosure of community staff members is also an effective way to increase information service satisfaction. Finally, trust plays a mediating role in the influence of information transparency and self-disclosure on information service satisfaction.
Originality/value
This paper innovatively uses uncertainty reduction theory to examine the effects of information transparency and self-disclosure on satisfaction with community information services. It expands the research in the field of information service satisfaction and extends the scope of the research subjects of self-disclosure.

Abstract
Purpose
This study draws upon the cultural values model, institutional theory and comparative capitalism to investigate differences in organizations’ approach to stakeholder management across country boundaries.
Design/methodology/approach
The authors developed a multi-dimensional scale, following the stakeholder culture framework (Jones et al., 2007) to identify differences in the prevalent stakeholder cultures in the USA, Italy and Japan. Data were collected in form of a questionnaire from managers of 530 companies in the USA, Italy and Japan.
Findings
Results show that there are important differences in the extent to which different stakeholder cultures exist in each of these three countries, and that the prevalence of stakeholder culture types in each country is influenced by the country’s cultural values and institutional arrangements.
Originality/value
Understanding stakeholder management beyond the conventional firm level to a wider institutional setting has important implications for the dissemination of corporate social responsibility (CSR) practices across cultures. Developing an understanding of how organizations’ stakeholder management approaches are embedded in the context of the institutional arrangements that exist in a particular country will lead to CSR practices that are better suited to the specific national context. It may also help in a more widespread acceptance of these concepts and practices.

This paper seeks to review gender differences in career goals and career tactics of men and women in the People's Republic of China (PRC).
Abstract
Purpose
This paper seeks to review gender differences in career goals and career tactics of men and women in the People's Republic of China (PRC).
Design/methodology/approach
Survey results were used to identify empirical differences in career beliefs of 233 managers employed in 16 organizations in the PRC.
Findings
Women and men were equally likely to value achievement, contributing to the family, and collectivism as career goals and to use loyalty to superiors, and networking as career tactics. Women were more likely than men to try to learn more and to want to get more education as career tactics.
Research limitations/implications
The non‐random sample that does not include every province in the PRC and the low scale internal consistency limit these findings.
Practical implications
Gender discrimination based on beliefs that women will be less loyal or ambitious are not justified by these results.
Originality/value
These results challenge stereotypes about Chinese women and provide information rarely examined.
