Special Issue Information
Heart rate and heart rate variability have been extensively researched in clinical settings over the past decades. Nonetheless, technological developments in the past few years have dramatically changed accessibility to such data for researchers, patients, and consumers.
Smartphones and wearable sensors allow for non-invasive and continuous measurement of heart rate and heart rate variability, enabling new applications and a better understanding of human physiology in response to both physical and psychological stressors. Additionally, continuous heart rate and heart rate variability measurements collected by means of novel technological developments can serve as input for the development of algorithms estimating other relevant parameters in the context of health and fitness, for example, energy expenditure, sleep stages, and cardiorespiratory fitness.
However, only a tiny fraction of smartphone applications and wearable sensors have been validated, often leaving many questions unanswered. Issues linked to, for example, artifact detection and correction, accuracy in different populations (e.g., the relation between PPG in different body locations and skin color), and the relative contribution of heart rate and heart rate derived features in various applications (e.g., sleep stage estimation) should be addressed by the scientific community.
In this Special Issue, you are invited to submit contributions describing the development and validation of technologies and methods to measure heart rate and heart rate variability using smartphones and wearable sensors, as well as derived applications relying on these inputs. Of particular interest are systematic evaluations of different technologies and methods aiming at measuring heart rate and heart rate variability, and derived applications.

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.
