Latest Advancements in Sensor Technologies and Monitoring Enabled by Blockchain Innovations

Dear Colleagues,

As sensors become ubiquitous across industrial, consumer, and public sector applications, properly monitoring, analyzing, and securing sensor data is crucial. Furthermore, digital twins—virtual representations of physical devices and processes—are reliant on extensive sensor data and analytics. Blockchain technologies can decentralize sensor networks, ensure data provenance, and enable new economic models for sensor data exchange to support digital twins.

We invite contributions exploring the intersection of sensors, monitoring, digital twins, and blockchain on topics including, but not limited to, the following:

• Consensus protocols and incentives optimized for IoT and sensor networks;
• Smart contracts and oracles for sensor monitoring, control, and actuation;
• Blockchain scalability, latency, and throughput for real-time sensor applications;
• Blockchain use cases and implementations in industrial IoT, smart cities, healthcare, etc.;
• Sensor data collection, analysis, integrity, security, and privacy using blockchains to support digital twins;
• Decentralized sensor networks, data marketplaces, and value chains to share data across digital twin models.

While blockchain faces challenges in terms of energy use, scalability, and hype cycles, decentralized and crypto-economic solutions hold promise for transforming the sensor systems and data that power digital twins. This Special Issue aims to bridge research on sensors, monitoring, digital twins, and blockchain to achieve new applications and address open issues. We welcome empirical and theoretical contributions from diverse disciplines.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
