Special Issue Information
Dear Colleagues,
During the 50th Earth Day, 22 April 2020, António Guterres, Secretary-General of the United Nations, released a message: “…Climate disruption is approaching a point of no return. We must act decisively to protect our planet from both the coronavirus and the existential threat of climate disruption”. He proposed six climate-related actions: “First: …we must deliver new jobs and businesses through a clean, green transition… Third: Fiscal firepower must drive a shift from the grey to green economy… Fourth: Public funds should be used to invest in the future…and flow to sustainable sectors and projects that help the environment and the climate…”
New ecologies such as IoT, smart cities, Industry 4.0, and precise agriculture will characterize economic development during the coming decades. Sensors can give a relevant contribution to a sustainable implementation of such ecologies, enabling the acquisition of data required for more efficient exploitation of energy and raw materials. Silicon-based electronic technologies cannot cope with the realization of green sensing systems.
It is estimated that 44.7x109 kg of e-waste was produced in 2016, 12.3x109 kg produced in the EU. Only 20% of this is formally recycled. E-wastes contain non-recyclable materials or pollutants that can contaminate the environment.
There is a need for novel materials and technologies, capable of giving meaningful answers to the need for sustainable development. Technologies for sensor fabrication are required that use renewable raw materials, save energy, and yield devices whose disposal does not produce any relevant environmental impact.
Bioderived polymers can allow producing green sensors. Cellulose has significant mechanical and electrical properties and is strong, biocompatible, and biodegradable. As a result, it has been proposed for realizing electronics, actuators, and sensors with a corresponding impressive growth of scientific contributions.
This Special Issue focuses on cellulose-based sensors. Contributions are sought on recent advantages in fabrication technologies, sensors, and sensing systems that exploit cellulose as the base of the materials.

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.
