Wireless Sensors for Intraoral Force Monitoring

A device for wireless intraoral forces monitoring is presented. Miniaturized strain gauge sensors are used for the measurements of forces applied by tongue and lips. A sensor interface IC is able to multiplex among four sensors and a low energy transmission module, equipped with an ARM Cortex–M0 core, is used for signal elaboration and remote wireless data transmission using Bluetooth® Low Energy standard protocol. The main novelty rely in the dynamic correction of the output corrupted by the prestrain issue. Moreover, the device shows a reduced dimension and the ability to transmit data wirelessly, without the use of external cables normally used in state-of-the-art intraoral monitoring devices

Digital twins as software and service development ecosystems in industry 4.0:towards a research agenda

Abstract While research on digital twins of cyber-physical systems within industry 4.0 is emerging, the software development perspective on digital twins remains under-explored. Contemporary definitions and examples of digital twins have covered company- or product-specific solutions or discussed the use of digital twins in rather proprietary value chains. This paper addresses the importance of taking an ecosystem view on software development on digital twins for industry 4.0 and outlines a framework for building a research agenda for such ecosystems. The framework includes three dimensions: scope of the digital twin software platform (internal, value chain, ecosystem), life-cycle phases of the industry 4.0 system related with the digital twin (creation, production, operation & maintenance, disposal), and level of integration between the twin and the physical system (model, shadow, twin). As this research-in-progress addresses examples of research questions in light of the framework, further research to build a full-scale research agenda based on a systematic literature review is suggested
