In this paper, we describe a technical design of wearable multi-sensor systems for physiological data measurement and wide medical applications, significantly impacted in telehealth. The monitors are composed of three analog front-end (AFE) devices, which assist with interfacing digital electronics to the noise-, time-sensitive physiological sensors for measuring ECG (heart-rate monitor), RR (respiration-rate monitor), SRL (skin resistivity monitor). These three types of sensors can be used separately or together and allow to determine a number of parameters for the assessment of mental and physical condition. The system is designed based on requirements for demanding environments even outside the realm of medical applications, and in accordance with Health and Safety at Work directives (89/391/CE and Seveso-II 96/82/EC) for occupational hygiene, medical, rehabilitation, sports and fitness applications.

A non-invasive solution for monitoring of the activity and dehydration of organisms is proposed in the work. For this purpose, a wireless standalone chemical sensor platform using two separate measurement techniques has been developed. The first approach for activity monitoring is based on humidity measurement. Our solution uses new humidity sensor based on a nanostructured TiO2 surface for sweat rate monitoring. The second technique is based on monitoring of potassium concentration in urine. High level of potassium concentration denotes clear occurrence of dehydration. Furthermore, a Wireless Body Area Network (WBAN) was developed for this sensor platform to manage data transfer among devices and the internet. The WBAN coordinator controls the sensor devices and collects and stores the measured data. The collected data is particular to individuals and can be shared with physicians, emergency systems or athletes' coaches. Long-time monitoring of activity and potassium concentration in urine can help maintain the appropriate water intake of elderly people or athletes and to send warning signals in the case of near dehydration. The created sensor system was calibrated and tested in laboratory and real conditions as well. The measurement results are discussed.

Detailed knowledge regarding sensor based technologies for the detection of food contamination often remains concealed within scientific journals or divided between numerous commercial kits which prevents optimal connectivity between companies and end-users. To overcome this barrier The End user Sensor Tree (TEST) has been developed. TEST is a comprehensive, interactive platform including over 900 sensor based methods, retrieved from the scientific literature and commercial market, for aquatic-toxins, mycotoxins, pesticides and microorganism detection. Key analytical parameters are recorded in excel files while a novel classification system is used which provides, tailor-made, experts' feedback using an online decision tree and database introduced here. Additionally, a critical comparison of reviewed sensors is presented alongside a global perspective on research pioneers and commercially available products. The lack of commercial uptake of the academically popular electrochemical and nanomaterial based sensors, as well as multiplexing platforms became very apparent and reasons for this anomaly are discussed.

During the last decade we have been witnessing fast development in the area of sensor technologies and communications that have enabled applications within the Internet of Things (IoT). Subsequently implementations of systems for continuous monitoring of human ́s vital parameters and daily activities started to appear. Since the ageing population is constantly increasing, the development of such applications is necessary. The growing number of sensor types and their producers introduces a problem concerning data formats and data representation. Sensor data representation is an important issue since we do not want to lose any useful information. Additional issue is the design of detection and evaluation algorithms. In the article we present briefly the considered types of sensors, proposed systems architecture, and experimental setup installed in a real apartment.

BACKGROUND: The work of members of rescue teams could be associated with very high physical and thermal loads. If not timely interrupted, any extreme labour-thermal load may lead to a failure of the body and fatal collapse. This risk may be significantly reduced by devices that monitor the response of the body during the intervention and inform rescuers about the need to interrupt the exposure when the critical value of the reference indicator is achieved. The aim of the study was to test the correlation between the data of the newly developed device for signaling the strain of rescuers and the indicators of physiological response of the body. MATERIAL AND METHODS: The tests were performed on 2 physically fit fire fighters dressed in a protective rescue suit and using insulating breathing apparatus, over a wide range of heat load under a model load on a bicycle ergometer in a climatic chamber. RESULTS: The study provided a significant correlation between the body temperature measured in the ear canal and the temperature under the suit sensed by the tested device - the Safety Ambient Monitor (SAM) (R = 0.9007). The temperature under the suit also correlated with the temperature of the chest skin (R = 0.8928) and heart rate (R = 0.8613). CONCLUSIONS: A statistically significant correlation was proven between the temperature sensed by the SAM and the body temperature. The technical solution of sensing the temperature under the suit using the verified SAM technology does not affect or limit fire fighters in their work and minimizes the possibility of damage to the sensor and signaling failures.

Virtuální realita představuje interaktivní uměle vytvořené prostředí izolované od reálného světa. Tato jedinečná technologie za využití imerzivity a gamifikace v posledním desetiletí vhodně doplňuje edukaci léčebných postupů a operačních technik. Náš tým se na základě pozitivních zkušeností s využitím virtuální reality v rehabilitaci rozhodl vyvinout vzdělávací model relativně nenáročné neurochirurgické operace, a to zavedení čidla intrakraniálního tlaku. Obsahem sdělení je vývoj modulu a první zkušenosti s jeho testováním ve výuce. Modul kombinuje realisticky navržené prostředí s virtuální asistencí a možností online kontroly vyučujícím. Za využití jednoduchého ovládání umožňuje bezpečný a libovolně opakovaný nácvik operace. Zdá se, že imerzivita a gamifi kace jsou klíčovým rozdílovým prvkem pro lepší zapamatování informací při nácviku, a tím zkvalitnění učebního procesu oproti jiným technikám. To nám potvrdili při testování modulu zdravotničtí pracovníci vývojového týmu a studenti lékařské fakulty a vyšší odborné zdravotnické školy. Předpokládáme, že aplikace tohoto modulu do nácviku operačních postupů by v budoucnu mohla efektivně doplnit stávající výukové metody a potenciálně urychlit vzdělávací křivku při nácviku daného výkonu.
Virtual reality represents an interactive, artificially created environment isolated from the real world. This unique technology, through immersion and gamification, has effectively complemented the education of therapeutic procedures and surgical techniques over the past decade. Based on positive experiences with the use of virtual reality in rehabilitation, our team decided to develop an educational model for a relatively straightforward neurosurgical procedure: the insertion of an intracranial pressure sensor. This report discusses the development of the module and the initial experiences with its testing in education. The module combines a realistically designed environment with virtual assistance and the possibility of online supervision by instructor. Its simple controls allow for safe and freely repeatedly practiced operations. Immersion and gamification appear to be key diff erentiators for better retention of information during training, thereby improving the educational process compared to other techniques. This has been confi rmed during module testing by healthcare professionals from the development team and students from the faculty of medicine and higher medical school. We anticipate that the application of this module in surgical training could effectively complement existing teaching methods and potentially accelerate the learning curve for the given procedure in the future.
This work is focused on problematic of biopotential signals measurements (EXG) using powerful SMART sensor system, composed of portable units, intended for in-time wireless measurement and evaluation of electrical activity, produced by skeletal muscles, human heart or brain. Here, we discuss very precise measurement features, which characterize this device (high gain, low noise, wireless data transfer, multi-probe measuring), some special features as low voltage and ultra-low power consumption were reached by application of the described amplifier in order to achieve its longer performance for daily use. It brings a lot of advantages to biomedical electronics and medical care. In order to optimize the performance of novel proposed smart biomedical instrument in our experimental part we have focused on measurement of surface electromyography (sEMG) signal to force ratio. These sEMG signals can illuminate our understanding of how the brain controls muscles to generate force and produce movement and can be used in such applications like as training of athletes, controlling robots, monitoring the physical capabilities of patients with motor disorders etc.
