Special Issue Information
Dear Colleagues,
For the most part, sensors are expected to provide a linear response to their stimuli. However, significant performance improvements are possible through the provision of nonlinear responses (e.g., logarithmic sensors) or when they are designed to be operated nonlinearly. In many cases, the sensitivity of a device to the input increases significantly as the device approaches its nonlinear operating region. Nonlinearities at the micro- and nano-scales have been utilized to improve the stability of oscillators or the sensitivity of sensors. Often, these nonlinearities are induced by pushing the device to the edge of nonlinearity from transduction, mechanical, or material origins and monitoring its response to the stimulus as perturbations. On the other hand, most statistical learning algorithms (i.e., machine learning) rely on some sort of nonlinear operation on signals for the transformation of data from one domain to another to reveal high-order interdependencies between variables or to compact the ranges. Increasingly, the nonlinear response of devices at different scales is employed as the required nonlinear mapping technique using physical devices or even in-materio.
The intention of this Special Issue is to publish a collection of leading research articles on the enhancement of the performance of materials, sensors, and sensor systems by employing inherent or designed nonlinearities.

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.
