We have developed a miniaturized fluorescence detection platform for droplet based assays that can monitor multiple channels using only a single photodetector and no lenses. To accomplish this, we take advantage of the high bandwidth of electronics and encode the signal from each channel using distinct micropatterned masks.

Abstract:

This article presents an ablative method of cutting masks from ultra-thin metal foils using nanosecond laser pulses. As a source of laser radiation, a pulsed fiber laser with a wavelength of 1062 nm with the duration of pulses from 15 to 220 nanoseconds (ns), was used in the research. The masks were made of stainless-steel foil with thicknesses of 30 µm, 35 µm, and 120 µm. Channels of different lengths from 50 to 300 µm were tested. The possibilities and limitations of the presented method are described. The optimization of the cutting process parameters was performed using the experiment plan

Patterned conformal conductive structures are used to realize flexible electronics for applications such as electronic skin, communication devices, and sensors. Thus, there is a demand for low-cost rapid fabrication techniques for flexible and stretchable conductors.

Abstract:

AbstractWearable and bio-implantable health monitoring applications require flexible memory devices that can be used to locally store body vitals prior to transmission or to support local data processing in distributed smart systems. In recent years, non-volatile resistive random access memories composed of oxide-based insulators such as hafnium oxide and niobium pentoxide have attracted a great deal of interest. Unfortunately, hafnium and niobium are not low-cost materials and may also present health challenges. In this work, we have explored the alternative of using titanium dioxide as the i

Background: During the coronavirus disease 2019 (COVID-19) pandemic face masks grew in importance as their use by the general population was recommended by health officials in order to minimize the risk of infection and prevent further spread of the virus. To ensure health protection of medical personal and other system relevant staff, it is of considerable interest to quickly test if a certain lot of filtering facepiece masks meets the requirements or if the permeability changes under different conditions.

Abstract:

When faced with outbreaks of infectious respiratory diseases in the past, the use of face masks has often been mandated. The world collectively experienced the devastating COVID-19 pandemic, which originated in Wuhan, China, in October 2019 and rapidly spread across the globe. Wearing face masks became the primary defense against infection. However, during this period, many individuals reported experiencing symptoms of dry eye. This study aimed to investigate the correlation between mask usage and dryness among healthcare workers.A hospital-based cross-sectional study was conducted using an on

Abstract:

The soldering process for aerospace applications follows stringent requirements and standards to ensure the reliability and safety of electronic connections in aerospace systems. For this reason, the quality control phase plays an important role to guarantee requirements compliance. This process often requires manual control since technicians’ knowledge is fundamental to obtain effective quality check results. In this context, the authors have developed a new open source dataset (SolDef_AI) to implement an innovative methodology for printed circuit board (PCB) defect detection exploiting the M

The Subway is the most important means of transport in Moscow. The active flows of passengers in the metro can contribute to the spread of infectious diseases with airborne and contact mechanisms of transmission, including the coronavirus infection COVID-19. The aim of the study was to assess the level of adherence to the use of personal protective equipment (facial masks, gloves) by passengers of the Moscow Subway. Materials and methods.
