Special Issue Information

Dear Colleagues,

Since Smith invented the flexible pressure sensor in 1954, new designs, manufacturing methods and applications of flexible sensors have been emerging constantly in consumer electronics, healthcare fields, automotive industries, etc. Sensitivity and flexibility are the most important factors when evaluating the performance of sensors; therefore, flexible pressure sensors are becoming increasingly important in environmental monitoring, wearable devices, intelligent devices, medical and other fields because of the limitations of pressure sensors made from stiff materials. Nowadays, flexible pressure sensors are widely used in electronic skin, wearable medical devices, etc., due to them being lightweight and having high sensitivity, high dynamic range, and high flexibility. In order to further adapt to the requirements of new applications, new flexible pressure sensors have to be continuously developed. Designing new functional materials, exploring novel nanostructures and films and seeking new integration technologies are three main topics. Enhancing sensor performance, expanding sensor arrays, developing self-drive and human implantation technology are key directions in flexible pressure sensors to further adapt them to new challenges.

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.

This article presents a prototype of a new, non-invasive, cuffless, self-calibrating blood pressure measuring device equipped with a pneumatic pressure sensor. The developed sensor has a double function: it measures the waveform of blood pressure and calibrates the device. The device was used to conduct proof-of-concept measurements on 10 volunteers. The main novelty of the device is the pneumatic pressure sensor, which works on the principle of a pneumatic nozzle flapper amplifier with negative feedback. The developed device does not require a cuff and can be used on arteries where cuff placement would be impossible (e.g., on the carotid artery). The obtained results showed that the systolic and diastolic pressure measurement errors of the proposed device did not exceed ±6.6% and ±8.1%, respectively. Full article
