“…This sensor is placed at the ankle, as this location allows a suitable integration of the sensor in the sock and has been reported as a suitable anatomical location for PPG acquisitions [ 10 ]. For the EDA acquisition, the BITalino EDA 081217 sensor (from PLUX, S.A., Lisbon, Portugal) was considered; this sensor works under the DC exosomatic measurement method, has been used in multiple research projects [ 37 , 38 , 39 ] and has a conductance measurement range of

“…As a reference device, the BITalino (r)evolution Plugged (PLUX, S.A., Lisbon, Portugal) was used, which was connected to the same type of sensors. It is worth mentioning that the BITalino has been widely used within the research community for EDA acquisitions using the BITalino EDA sensor (as used in this experiment) [ 37 , 38 , 39 , 41 ]. Furthermore, this device has also been used for PPG acquisitions in laboratory research contexts [ 42 , 43 ].…”

Wearable devices have been shown to play an important role in disease prevention and health management, through the multimodal acquisition of peripheral biosignals. However, many of these wearables are exposed, limiting their long-term acceptability by some user groups. To overcome this, a wearable smart sock integrating a PPG sensor and an EDA sensor with textile electrodes was developed. Using the smart sock, EDA and PPG measurements at the foot/ankle were performed in test populations of 19 and 15 subjects, respectively. Both measurements were validated by simultaneously recording the same signals with a standard device at the hand. For the EDA measurements, Pearson correlations of up to 0.95 were obtained for the SCL component, and a mean consensus of 69% for peaks detected in the two locations was obtained. As for the PPG measurements, after fine-tuning the automatic detection of systolic peaks, the index finger and ankle, accuracies of 99.46% and 87.85% were obtained, respectively. Moreover, an HR estimation error of 17.40±14.80 Beats-Per-Minute (BPM) was obtained. Overall, the results support the feasibility of this wearable form factor for unobtrusive EDA and PPG monitoring.

“…Both these devices have been validated for their use in biosignal acquisitions, including PPG monitoring in research contexts. For instance, the BITalino device has been widely used within the research community for biosignal acquisitions [ 35 , 36 , 37 , 38 , 39 , 40 ]. Moreover, the ScientISST CORE [ 41 ] is a novel signal acquisition board especially developed for biomedical applications, and has also been used in similar research contexts [ 22 , 42 , 43 , 44 , 45 ].…”

Photoplethysmography (PPG) is used for heart-rate monitoring in a variety of contexts and applications due to its versatility and simplicity. These applications, namely studies involving PPG data acquisition during day-to-day activities, require reliable and continuous measurements, which are often performed at the index finger or wrist. However, some PPG sensors are susceptible to saturation, motion artifacts, and discomfort upon their use. In this paper, an off-the-shelf PPG sensor was benchmarked and modified to improve signal saturation. Moreover, this paper explores the feasibility of using an optimized sensor in the lower limb as an alternative measurement site. Data were collected from 28 subjects with ages ranging from 18 to 59 years. To validate the sensors’ performance, signal saturation and quality, wave morphology, performance of automatic systolic peak detection, and heart-rate estimation, were compared. For the upper and lower limb locations, the index finger and the first toe were used as reference locations, respectively. Lowering the amplification stage of the PPG sensor resulted in a significant reduction in signal saturation, from 18% to 0.5%. Systolic peak detection at rest using an automatic algorithm showed a sensitivity and precision of 0.99 each. The posterior wrist and upper arm showed pulse wave morphology correlations of 0.93 and 0.92, respectively. For these locations, peak detection sensitivity and precision were 0.95, 0.94 and 0.89, 0.89, respectively. Overall, the adjusted PPG sensors are a good alternative for obtaining high-quality signals at the fingertips, and for new measurement sites, the posterior pulse and the upper arm allow for high-quality signal extraction.

Snails are a delicacy that people have been eating for centuries. Products made from this meat contain few calories per 100 grams and fill the human body with useful elements. They can be prepared by cooking, namely escargot with various fillings (Burgundy snails, Catalan snails, Asian snails, snails with porcini mushrooms), and also, now a new type of product containing m gastropod mollusks – puffs with snails. If determining the quality and nutritional value of meat, it is necessary to determine indicators, if there is doubt about its suitability, which characterize the chemical composition, freshness, as well as the determination of microbiological contamination. The purpose of this work was to determine the features and practical aspects of examination of gastropod molluscs – snails. The studies highlighted in the scientific publications of Ukrainian scientists are significant, but they relate to the determination of the degree of freshness of snail meat by various methods and the organization of snail farming in various ways. Snails are a delicacy, dietary product of high commercial value and belong to the few types of food products. They are subject to mandatory veterinary and sanitary examination. A special feature of examination of snails is microbiological and bacteriological types of control to establish their general safety. In the course of research, first of all, the organoleptic indicators of molluscs, which reflect their freshness, are determined. Next, they conduct research on the presence of pathogenic microflora, determine the presence of radionuclides, conduct bacteriological research. In addition to the mollusk itself, the water with which they are irrigated, as well as the soil – the permanent habitat of snails – are also examined for the presence of helminth eggs. It was established that it is necessary to carry out laboratory control of each batch of snail meat for the content of microorganisms, such as MAFAnM, BGKP (coliforms), coagulase-positive staphylococcus (S. aureus), bacteria of the genus Proteus, pathogenic microorganisms, including salmonella, Listeria monocytogenes, radionuclides – Cs-137 and Sr-90 and helminths (nematodes).
