Distributed Intelligent MEMS: Progresses and Perspectives

International audienceMEMS research has until recently focused mainly on the engineering process, resulting in interesting products and a growing market. To fully realize the promise of MEMS, the next step is to add embedded intelligence. With embedded intelligence, the scalability of manufacturing will enable distributed MEMS systems consisting of thousands or millions of units which can work together to achieve a common goal. However, before such systems can become a reallity, we must come to grips with the challenge of scalability which will require paradigm-shifts both in hardware and software. Furthermore, the need for coordinated actuation, programming, communication and mobility management raises new challenges in both control and programming. The objective of this article is to report the progresses made by taking the example of two research projects and by giving the remaining challenges and the perspectives of distributed intelligent MEMS

Diving into the vertical dimension of elasmobranch movement ecology

Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses the knowledge gap of vertical movements by compiling the first global synthesis of vertical habitat use by elasmobranchs from data obtained by deployment of 989 biotelemetry tags on 38 elasmobranch species. Elasmobranchs displayed high intra- and interspecific variability in vertical movement patterns. Substantial vertical overlap was observed for many epipelagic elasmobranchs, indicating an increased likelihood to display spatial overlap, biologically interact, and share similar risk to anthropogenic threats that vary on a vertical gradient. We highlight the critical next steps toward incorporating vertical movement into global management and monitoring strategies for elasmobranchs, emphasizing the need to address geographic and taxonomic biases in deployments and to concurrently consider both horizontal and vertical movements

Anthropocentric Workplaces of the Future Approached through a New Holistic Vision

Part 1: Knowledge-Based SustainabilityInternational audienceThe human dimension is growing in importance in the cul- tural and scientific debate surrounding the arising of workplace and fac- tory of the future visions. Having people at the centre of the factory is already recognized as a main enabler for making the most out of their skills and capacities while at the same time achieving an environment that can both motivate employed workers and attract new skilled ones. The present paper proposes a novel concept aimed at defining new so- cially sustainable workplaces that adapt to workers’ anthropometric di- mensions within worker-aware production systems that are designed and operated to capitalize on workers’ skills and experience while at the same time promoting their development. Moreover it envisions the integration of the factory in the social and environmental context by promoting the creation and provision of worker-centric services that turn the factory from a society-affecting entity into an integration-promotion body
