Special Issue Information

Dear Colleagues,

The 2019 International Conference on Smart Sensors (http://www.icsstw.org/) (ICSS 2019) will be held in Hsinchu, Taiwan, from 3–4 June 2019.

The conference is a joint venture of the 24th Symposium of the Association of Chemical Sensors in Taiwan and the 22nd Nano Engineering and Microsystem Technology Conference. ICSS 2019 aims to promote research in sensors and NEMS/MEMS technology and advance the industry–research collaboration. The topics include (but are not limited to):

  1. Chemical sensors: Electrochemical sensors/optical sensors/semiconductors and electric sensors;
  2. Biosensors: Nanomaterial, enzyme-based or cell-based biosensors/immunosensors for clinical, food, environment, drug, etc. application/DNA- or RNA-related biosensors for clinical, food, environment, drug, etc. application;
  3. Microfluidics for medical and biological applications: Lab-on-a-chip microdevices/portable and emerging microfluidics technologies/medical application techniques classified by clinical subjects;
  4. MEMS and NEMS fabrication: Mechanical and physical sensors and microsystems;
  5. Microfluidics for separations, reactions, and synthesis;
  6. Applied MEMS and applied microfluidics: Energy harvesting/power/RF/optical/acoustic MEMS for sensor applications, enabling sensor technologies for IoT applications.

This Special Issue is being published in cooperation with ICSS 2019. The authors who presented their research papers at the conference are invited to submit full research papers to the Special Issue. The scope of the Special Issue is not limited to the selected works from ICSS 2019, and welcomes outstanding research papers related to the topics of interest listed above.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Enhanced hydrogen sensing performance of Pt Schottky diodes on ZnO single crystal wafers in humid ambient conditions is reported using a polymethylmethacrylate (PMMA) membrane layer. ZnO diode sensors showed little change in forward current when switching to wet ambient H2 conditions with 100% relative humidity. This sensitivity drop in the presence of water vapor can be attributed to surface coverage of hydroxyl groups on the Pt surface in humid ambient conditions. The hydrogen sensitivity of PMMA-coated diode sensors recovered up to 805% in wet H2 ambient conditions at room temperature. The PMMA layer can selectively filter water vapor and allow H2 molecules to pass through the membrane layer. It is clear that the PMMA layer can effectively serve as a moisture barrier because of low water vapor permeability and its hydrophobicity. In both dry and wet conditions, ZnO diodes exhibited relatively fast and stable on/off switching in each cycle with good repeatability. Full article
