Article Synopsis
- Transpulmonary pressure calculation typically requires esophageal pressure, which is a complicated process to calibrate.
- A new digital filter that removes heartbeat noise from central venous pressure (CVP) waveforms, resulting in a filtered CVP (f-CVP), was developed to simplify this measurement.
- In this study, f-CVP was evaluated and found to estimate esophageal respiratory swings more accurately than CVP alone and effectively identify high transpulmonary pressure levels in patients with acute respiratory failure.
In this paper, an FPGA (Field Programmable Gate Array)-based digital architecture for the measurement of quartz crystal microbalance (QCM) oscillating frequency of transient responses, i.e., in QCM-D (QCM and Dissipation) applications, is presented.

The study is targeted at characterizing the dynamic behavior of a typical ion-current measurement system based on a spark-plug. Starting from the preliminary study published in a previous work, the authors propose a refined model of the electrode (spark plug), based on the Langmuir probe theory, that incorporates the physical surface effects and proposes an optimized design of the conditioning electronics, which exploits a low frequency AC square wave biasing of the electrodes and allows for compensating some relevant parasitic effects.

- Researchers propose a new, affordable gravimetric system to monitor access in public spaces by integrating various sensors like metal detectors and cameras for better event tracking.
- This system focuses on identifying "notable" events, which include irregular occurrences, such as multiple people passing through security gates, and useful data for assisting individuals with disabilities or for statistical purposes.
- The gravimetric sensor utilizes a reliable design with steel plates and load cells, achieving impressive detection accuracy (95.3%) for irregular events and effective classification of other event types.
The aim of this work is to investigate the gas sensing performance of single wall carbon nanotubes (SWCNTs)-based conductive sensors operating at low-medium temperatures (<250 °C). The investigated sensing films consists of an SWCNT network obtained by drop-casting a SWCNT suspension. Starting from this base preparation, different sensing devices were obtained by decorating the SWCNT network with materials suitable for enhancing the sensitivity toward the target gas.

The gas sensing properties of mixtures of two different metal oxide nanoparticles, prepared via low-cost routes, are investigated. The responses to both an oxidizing (NO₂) and a reducing gas (CO) are analyzed.

Their electrical properties have monitored directly during deposition to optimize their sensing performance. Experimental results with oxidizing (NO₂) as well as reducing (CO) gases in both air and inert gas carriers are discussed and modeled.
