Frontiers in Capacitive Sensors

Dear Colleagues,

Capacitive sensors have been used in industrial applications for decades. In the last years, capacitive sensors have been included in consumer electronics as a capacitive touch screen for smartphones and sensors for ECG in biomedical applications. In fact, capacitive sensors have been subject to more research within industrial and biomedical applications over the past ten years. A capacitive sensor is a device that bases its operation on the capacitance change. Typically, a capacitor is made out of two-conductor layers separated by a dielectric material. The capacitance change can be produced by changing the separation of the two (or more) conductive layers, changing the conductive layers' area, or changing the permittivity of the dielectric material. These features, added to cost-effectiveness, low-power consumption, low noise performance, reliability, and high adaptability to the environment, become capacitive sensors into versatile sensors used in many different applications. Examples of this are the use of flexible capacitive pressure sensors to measure the plantar pressure, textil capacitive sensors to monitoring respiration or ECG of people, or capacitive sensors to measure the liquid level in a tank. Accordingly, this Special Issue seeks to showcase research papers, communications, and review articles that focus on novel developments of capacitive sensors and their applications, i.e., on the novel manufacturing process and uses of capacitive sensors.

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. Micromachines is an international peer-reviewed open access monthly 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.
