Dear Colleagues,

With the increase in consumer electronic products such as smart phones and tablets, the demands for biometric sensing capabilities are also increasing. Among a variety of biometric sensing systems, capacitive fingerprint sensors are one of the most popular biometric sensing techniques in the current market, with smartphones commonly adopting capacitive fingerprint sensors for a biometric identification method. 

The Internet of Things is another fast-growing area that has increasing demands for authentication techniques. Capacitive fingerprint sensors are again a popular choice due to the compact size and low power consumption of the hardware.

Apart from biometric applications, capacitive fingerprint sensors have also been used for skin measurements, such as water content and solvent penetration measurements, as well as skin texture and skin micro-relief measurements, and so on. Machine learning and deep learning have also been used for analysing capacitive skin images.

I am excited to be the Guest Editor of this Special Issue. This Special Issue targets researchers working in the field of capacitive fingerprint sensors, as well as the end-users who utilise the sensors for their own applications. We hereby invite the international community with expert knowledge of capacitive fingerprint sensors to participate in this high impact journal, aiming at the proper dissemination of our research.

Prof. Perry Xiao
Guest Editor

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.
