“…A new technology, which is substrate integrated waveguide - SIW based on resonant cavity, was proposed and performed for electrical characterization of liquids 9 . Alternatively, the reflectance and transmittance values of liquids were determined by using low-lost spectrometer 10 . The various liquids in the bag or on the human can be identified and classified using a multivariate data analysis algorithm, depending on the scattering parameters (dB) obtained with the microwave spectroscopy system.…”

Before separating or classifying hazardous/unsafe liquids, a system must be identified which can best measure certain liquids. The preferred measurement system can be useful, quick response, rapid measurement and so on. However, these features are not sufficient to classify the liquids in different containers. Especially at security points, containers of liquids carried by people may be different. Therefore, it has been investigated whether classification can be made by using the response of different containers to electromagnetic radiation. When the ring resonator measurement method is used in the 1–1.4 GHz frequency range, a successful separation process is carried out, even if the containers were made of different materials. Nevertheless, a well-known k-means algorithm has been used to analyze the measurement results of selected liquids.

“…The democratization of design in scientific innovation has also been explored, with case studies highlighting the design and social impact of collaboratively designed open source hardware instruments [11]. Furthermore, tools for public participation in science have been developed to support the efficient and inclusive dissemination of Open Science Hardware (OSH), fostering greater community involvement in scientific endeavours, In the realm of material identification, the potential of low-cost hardware combined with open source software has been utilised in reality [12], emphasizing…”

Before the COVID-19 pandemic, open source hardware development grew steadily. However, the pandemic rapidly accelerated the global acceptance of open source hardware solutions. While open source software has long been vital in the ICT sector, this concept now extends to physical hardware production. Notably, the medical and energy fields have prominently embraced this shift, utilizing 3D printing to actualize open source designs. This study explores pre-pandemic Open Source Scientific practices, aiming to extract insights for a stronger future open source framework. Through an in-depth case study, we illuminate best practices, exemplary applications, and propose a framework for upcoming open source hardware projects. Additionally, this paper categorizes key areas of open source hardware innovation, outlining key sections and areas, thus offering a comprehensive view of the open source hardware landscape.

“…Lowcost handheld devices are being developed and produced meaningful results in comparison to the laboratory-grade devices, which in future may be available for routine clinical use. 56,57 Recent innovations have led to the development of low-cost SDFI 58 and low-cost smartphone-based LSCI, 59 which might be available for routine diagnostic purposes in the future. However, the research in these fields is still in infancy currently and more studies are required to prove the definitive role of these modalities in diagnosis and monitoring of PWS.…”

Port-wine stains (PWS) are benign, congenital, progressive lowflow capillary vascular malformations of the human skin formed by immature ectactic venular structures. They may also be acquired sporadically and the etiology is multifactorial resulting in impaired differentiation of dermal endothelial cells. 1 It is caused by genetic mosaicism in GNAQ and GNA11 genes. 1 PWS has a prevalence of 0.3%-0.5% in neonates and is usually located in the head and neck region as pinkish macular lesions. 2 In contrast to hemangiomas, PWSs are not self-involuting and rather progress in size and evolve into hypertrophic or nodular lesions by the 5th decade of life leading to cosmetic disfigurement.Nodular and hypertrophic lesions are associated with the risk of spontaneous hemorrhage. There is also a risk of functional compromise when progressively enlarging lesions are present near the
