“…Photodetectors are devices converting optical signals into electric signals, which are critical function units of extensive applications spanning LiFi communication, [ 210 ] target motion tracking, [ 211 ] optical imaging, [ 212 ] optoelectronic memory, [ 213 ] biometric authentication, [ 214 ] intelligent robots, [ 215 ] internet of things, [ 95 ] just to name a few. Basically, photocarriers are generated upon light excitation with sufficiently high photon energy, where electrons transit from conduction band to valence band of the photoactive materials.…”

2D layered materials (2DLMs) have come under the limelight of scientific and engineering research and broke new ground across a broad range of disciplines in the past decade. Nevertheless, the members of stoichiometric 2DLMs are relatively limited. This renders them incompetent to fulfill the multitudinous scenarios across the breadth of electronic and optoelectronic applications since the characteristics exhibited by a specific material are relatively monotonous and limited. Inspiringly, alloying of 2DLMs can markedly broaden the 2D family through composition modulation and it has ushered a whole new research domain: 2DLM alloy nano-electronics and nano-optoelectronics. This review begins with a comprehensive survey on synthetic technologies for the production of 2DLM alloys, which include chemical vapor transport, chemical vapor deposition, pulsed-laser deposition, and molecular beam epitaxy, spanning their development, as well as, advantages and disadvantages. Then, the up-to-date advances of 2DLM alloys in electronic devices are summarized. Subsequently, the up-to-date advances of 2DLM alloys in optoelectronic devices are summarized. In the end, the ongoing challenges of this emerging field are highlighted and the future opportunities are envisioned, which aim to navigate the coming exploration and fully exert the pivotal role of 2DLMs toward the next generation of electronic and optoelectronic devices.

“…The pandemic has placed higher demands on the automation and safety of robots and has promoted the debugging and innovation of related robots in technology. For example, a medical robot arm that can be controlled by Bluetooth from a smartphone [11]; mobile robots using a visible light communication system, which reduces the influence of traditional radio systems on patients and medical equipment [12]; and the indoor positioning system of mobile robot using optical sensors, which greatly improves their accuracy and stability [13]. The situation further increases the possibility of robots being used for emergency response in the event of a public health emergency.…”

Various intelligent technologies have been applied during COVID-19, which has become a worldwide public health emergency and brought significant challenges to the medical systems around the world. Notably, the application of robots has played a role in hospitals, quarantine facilities and public spaces and has attracted much attention from the media and the public. This study is based on a questionnaire survey on the perception and reception of robots used for medical care in the pandemic among the Chinese population. A total of 1667 people participated in the survey, 93.6% of respondents were pursuing or had completed a bachelor, master or even doctorate degree. The results show that Chinese people generally held positive attitudes towards “anti-pandemic robots” and affirmed their contribution to reducing the burden of medical care and virus transmission. A few respondents were concerned about the issues of robots replacing humans and it was apparent that their ethical views on robots were not completely consistent across their demographics (e.g., age, industry). Nevertheless, most respondents tended to be optimistic about robot applications and dialectical about the ethical issues involved. This is related to the prominent role robots played during the pandemic, the Chinese public’s expectations of new technologies and technology-friendly public opinion in China. Exploring the perception and reception of anti-pandemic robots in different countries or cultures is important because it can shed some light on the future applications of robots, especially in the field of infectious disease control.

In aerospace ground test system, positioning accuracy estimation of spacecraft simulator has an important influence on the trajectory planning and obstacle avoidance optimization. In this study, the fusion strategy of multi-laser-ranging-sensors is used to analyse the principle of laser ranging in the positioning of spacecraft simulator. On this basis, effect of measurement error on the positioning accuracy of spacecraft simulator is analysed, and theoretical derivation are performed. In order to accurately estimate the positioning accuracy, the algorithm based on Monte Carlo and Anderson-Darling test are introduced. Finally, simulations and experiments were conducted for the above algorithm. The result shows that the fusion strategy of multi-laser ranging sensors is reasonable. Compared with traditional positioning and accuracy estimation methods of spacecraft simulator, the proposed method is more precise for the accuracy estimate and is more convenient for engineers to use.
