Special Issue Information

Dear Colleagues,

We cordially invite you to contribute to a Special Issue of Micromachines entitled “Multisensor Arrays”. The development of sensors has become essential in a wide range of applications, including environmental and health monitoring, as well as in the pharmaceutical and food industries. The use of multisensor arrays can improve results compared to the use of a single sensor, mainly due to more complete coverage of the physical/chemical phenomena involved. Subsequently, the data acquired from these multisensor systems can be assessed and even qualitatively and/or quantitatively related to the sample’s parameters through multivariate data processing tools. This Special Issue aims to showcase a collection of manuscripts from scholars worldwide working on various aspects of multisensor systems development, from fundamental research to practical applications. In this Special Issue, original research articles and reviews are welcome. Research areas may include, but are not limited to, the following:

  • Multisensor systems;
  • Sensor arrays;
  • Electronic tongues;
  • Electronic noses;
  • Chemical sensors;
  • Biosensors;
  • Hybrid sensor arrays;
  • Food quality monitoring;
  • Environmental monitoring;
  • Health monitoring;
  • Drugs/pharmaceutical applications;
  • Data analysis;
  • Multivariate data processing tools;
  • Supervised and unsupervised methods;
  • Embedded electronics.

We look forward to receiving your contributions to this exciting Special Issue, which will offer invaluable insights into the development of multisensor systems.

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.

In this work, we present a compact, bifunctional chip-based sensor setup that measures the temperature and electrical conductivity of water samples, including specimens from rivers and channels, aquaculture, and the Atlantic Ocean. For conductivity measurements, we utilize the impedance amplitude recorded via interdigitated electrode structures at a single triggering frequency. The results are well in line with data obtained using a calibrated reference instrument. The new setup holds for conductivity values spanning almost two orders of magnitude (river versus ocean water) without the need for equivalent circuit modelling. Temperature measurements were performed in four-point geometry with an on-chip platinum RTD (resistance temperature detector) in the temperature range between 2 °C and 40 °C, showing no hysteresis effects between warming and cooling cycles. Although the meander was not shielded against the liquid, the temperature calibration provided equivalent results to low conductive Milli-Q and highly conductive ocean water. The sensor is therefore suitable for inline and online monitoring purposes in recirculating aquaculture systems. Full article

Insufficient control of tomato ripening before harvesting and infection by fungal pests produce large economic losses in world tomato production. Aroma is an indicative parameter of the state of maturity and quality of the tomato. This study aimed to design an electronic system (TOMATO-NOSE) consisting of an array of 12 electrochemical sensors, commercial metal oxide semiconductor sensors, an optical camera for a lateral flow reader, and a smartphone application for device control and data storage. The system was used with tomatoes in different states of ripeness and health, as well as tomatoes infected with Botrytis cinerea. The results obtained through principal component analysis of the olfactory pattern of tomatoes and the reader images show that TOMATO-NOSE is a good tool for the farmer to control tomato ripeness before harvesting and for the early detection of Botrytis cinerea.
