With the tremendous progress of Internet of Things (IoT) and artificial intelligence (AI) technologies, the demand for flexible and stretchable electronic systems is rapidly increasing. As the vital component of a system, existing computing units are usually rigid and brittle, which are incompatible with flexible and stretchable electronics. Emerging memristive devices with flexibility and stretchability as well as direct processing-in-memory ability are promising candidates to perform data computing in flexible and stretchable electronics. To execute the in-memory computing paradigm including digital and analogue computing, the array configuration of memristive devices is usually required. Herein, the recent progress on flexible and stretchable memristive arrays for in-memory computing is reviewed. The common materials used for flexible memristive arrays, including inorganic, organic and two-dimensional (2D) materials, will be highlighted, and effective strategies used for stretchable memristive arrays, including material innovation and structural design, will be discussed in detail. The current challenges and future perspectives of the in-memory computing utilizing flexible and stretchable memristive arrays are presented. These efforts aim to accelerate the development of flexible and stretchable memristive arrays for data computing in advanced intelligent systems, such as electronic skin, soft robotics, and wearable devices.

Ambient Intelligence (AmI) is the emerging computing paradigm used to build next-generation smart environments. It provides services in a flexible, transparent, and anticipative manner, requiring minimal skills for human-computer interaction. Recently, AmI is being adapted to build smart systems to guide human activities in critical domains, such as, healthcare, ambient assisted living, and disaster recovery. However, the practical application to such domains generally calls for stringent dependability requirements, since the failure of even a single component may cause dangerous loss or hazard to people and machineries. Despite these concerns, there is still little understanding on dependability issues in Ambient Intelligent systems and on possible solutions. This paper provides an analysis of the AmI literature dealing with dependability issues and to propose an innovative architectural solution to such issues, based on the use of runtime verification techniques.

High-resolution, large-scale printing of highly conductive AgNWs for flexible and stretchable electronics using EHD printing is presented. The printed patterns show the smallest line width of 45 μm and electrical conductivity as high as ∼5.6 × 106S m−1. AgNW-based wearable heaters and ECG electrodes are fabricated.


Subject Aviation cybersecurity. Significance The aviation sector has significant experience tackling physical security risks, such as lasers shone into the cockpit or preventing dangerous items being taken aboard (especially since the September 11, 2001 terrorist attacks). Cybersecurity is proving a tougher challenge not only for corporate IT systems but also operational air traffic control and management systems. Meanwhile, it is becoming easier and cheaper for potential attackers to interfere with electronic systems. Impacts State-linked cyberattacks against critical infrastructure bode ill for aviation cybersecurity. Commercial aviation regulation is fairly consistent globally; no region is particularly ahead or behind on safety rules. Risks posed by malicious uses of artificially intelligent systems in aviation are largely an academic discussion at present.
