Wearable and Flexible Integrated Sensors

Dear Colleagues,

Wearable sensors have received tremendous attention over the past decade thanks to their employment in the Internet of Things market. Moreover, these devices can also be used for medical purposes in the healthcare field as they can closely monitor an individual’s physical activities as well as assess their health status. The majority of these systems are composed of a mixed-signal front-end circuit, microcontroller unit, communication hardware to transmit data to a remote center, and battery with its power management block and memory, all integrated and interconnected on the same printed circuit board. In such a context, one of the main hurdles to employment in long-term monitoring has been the comfort in wearing such devices, which are dependent on its dimensions and weight. Advances in materials science have enabled the development of flexible and stretchable substrates that allow fabricating comfortable and lightweight wearable tools for non-invasive, long-term wearable sensing applications. In order to be both comfortable and wearable, it is fundamental that the energy source as well as the electronics section is flexible and stretchable. Articles on flexible nanogenerators for conversion of mechanical energy into electrical energy will also be considered for publication. This call for papers is concerned with the last advances in the field of flexible substrates which allow hosting complex mixed-signal systems, textile-based sensors, and e-textile-based systems that integrate sensing capabilities into garments and flexible energy sources and harvesting systems for powering the devices. 

We solicit papers covering (but not limited to) one or more of the following topics:

• Novel materials for flexible sensors and electronics
• Flexible sensor and interface systems
• Flexible and stretchable substrates and devices
• Organic and hybrid semiconductors with printing capabilities
• Carbon-based materials for stretchable transistors
• Flexible and stretchable organic field-effect transistors (OFETs)
• Graphene-based flexible electronics
• Printed electronics and sensors
• Flexible integrated systems for wearable biomedical sensors
• Flexible energy suppliers
• Flexible supercapacitors
• Flexible harvesters

Prospective authors are invited to submit original or review contributions for publication in this Special Issue.

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 250 words) can be sent to the Editorial Office for assessment.

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. Electronics 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 2400 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.
