Development of Sensors for Electronic and Optical Devices

Dear Colleagues,

This Special Issue of Sensors is devoted to reports on recent research based on the development of sensors for electronic and optical devices. Sensors are an integral part of our life. Sensors are the heart of daily life applications such as TV remotes, fiber optical communication systems, fire alarms, etc. The minimized size of modern devices demands nano-size sensors. With the advancement of nanoscience and nanotechnology, nanostructures of different materials have been synthesized and studied for different types of sensing applications. Due to quantum confinement and lattice modifications, nanomaterials show many extraordinary electronic and optoelectronic properties in their bulk state. Nanomaterials are very useful for developing advanced-level electronic and optoelectronic sensors for modern devices. Nanomaterials show very high chemical reactivity and thereby have superior sensing properties. Another advantage of nanomaterials is their easily tunable physical properties, which promote selectivity in sensing applications. These nanomaterials may be used in sensing devices as the active element that captures the stimulus and can also be used as the transducers used to convert a change due to stimulus into an observable output signal. Some nanomaterials may be used as components of circuits for sensing applications.  The field of sensors relies upon a wide variety of materials and devices that are used to capture physical, chemical, or biological stimuli and produce output signals. The synthesis of stable sensing materials for achieving high selectivity and other technical aspects is highly desirable. The performance of sensing materials depends upon their microstructural properties, such as morphology, crystalline phase, etc. Therefore, the research on different approaches for the synthesis of nanomaterials and their utilization in sensing applications is of great importance. Controlled growth and improved synthesis methods for nanomaterials are being explored in order to use these materials in sensor applications. In this Issue, several reports are presented on the synthesis of nanomaterials via different approaches and the utilization of these materials in optical and electronic sensors for modern devices.

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.
