There is a growing demand for wearable technologies with continuous and minimally intrusive physiological parameter monitoring capabilities. Continuous respiratory rate monitoring using a three-axis accelerometer from the sternum or abdomen is highly challenging due to motion corruption and presents a potential area of research. A system design for continuous and long term respiratory rate monitoring, in a wearable form factor with capability of remote monitoring is presented in this paper. The device runs on a low power ARM Cortex M0 microcontroller and uses inbuilt BLE (Bluetooth Low energy) module for wireless connectivity. A respiratory rate computation algorithm using motion artifact rejection is implemented on the device for reliable performance. Respiratory rate computation by the device was validated in a controlled setting, against gas pressure sensor on 20 subjects. The system architecture, device design, algorithm implementation and experimental validation of the proposed modality are presented.","PeriodicalId":235051,"journal":{"name":"2017 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129259087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is an indicator of vegetative innervation, and disturbances of nervous systems. Sodium chloride, for instance, is one of the indicators of cystic fibrosis. The paper illustrates the modeling of a sensing system and its related architectures to detect the sodium chloride for the diagnosis of cystic fibrosis. The system is partly in micro and nanotechnology. The paper presents first a dedicated hardware for conditioning and processing signal deriving from a sensor for sweat characterization. The experimental board has been realized using common components but it can be reduced to micro and nanotechnology configuration. This realization, even carried out with a traditional board, demonstrates two positive results: nonlinearity of sodium concentration and reaction time. However, noise contributes to lower the experimental uncertainty. To improve the features, especially in terms of lowering uncertainty and further reaction time (response time), a design of a dedicated sensor for detecting sweat is performed. It is an ISFET (ion-sensitive field effect transistor) using MEMS technology.","PeriodicalId":235051,"journal":{"name":"2017 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116551910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors have developed a measurement technique for the non contact measurement of blood pressure (BP) as manifest in the carotid artery, based on the use of a laser Doppler vibrometer (LDV). The LDV produces a signal that can be related to the continuous pressure pulse waveform. As such, the signal supports the calculation of some physiologically important time intervals. In this paper, we provide a comparison with the pressure waveform recorded using conventional applanation tonometry: the waveform has an analogous shape and, overall, provides the same characteristics in the time axis. More in details, results show that the systolic blood pressure have a mean deviation of 8% with respect to the reference value (obtained from tonometric data). Fundamental aspects to be considered are the precise laser pointing perpendicularly to the measurement site (to optimize the signal-to-noise ratio), the measurement conditions (e.g. the subject has to remain as still as possible) and also the reflective properties of the subject's skin, which can be improved by applying a proper reflective lotion or tape. The major factors contributing to uncertainty of the LDV measures have been evaluated, in order to identify ways to enhance performance. The current uncertainty value of 15% is not negligible, but does not greatly exceed that of the standard BP measuring devices.","PeriodicalId":235051,"journal":{"name":"2017 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"490 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133286901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the coefficient of variation was examined as a measure for identifying differences related to acceleration driving event variability between 12 physically, cognitively, and general health stable older adult drivers and 16 older adult drivers with declining physical, cognitive, or general health status over a one year period. Declining older adult drivers had significantly lower acceleration coefficient of variation than stable drivers for acceleration event subsets with final velocities between 60 and 100 km/hr, changes in velocities between 15 and 30 km/hr and between 60 and 75 km/hr, and changes in heading between 70 and 180 degrees, which may indicate a reduced adaptation of acceleration driving patterns. Further investigation of acceleration coefficient of variation is warranted to determine whether the decreased acceleration variability in declining drivers is due to physical, cognitive, or general health declines, and to determine the accuracy of this measure at identifying older adults with declining health and those with unsafe driving.","PeriodicalId":235051,"journal":{"name":"2017 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133910715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The readout circuit converts the output voltage of a pH sensor, which corresponds to the pH value of a solution under measurement, to a square-wave signal with its frequency being proportional to the pH sensor output voltage. A simple calibration method is employed in the design which makes the output frequency stay constant over process, supply voltage and temperature variations. The prototype system is designed and fabricated using a standard 0.13-µm CMOS process and the measurement results show that the sensor has good linearity to cover the entire pH value range from 0–14. The proposed sensor consumes 12.8 µW of power with 1.25 V supply voltage for a typical pH value of 7 while occupying a die area of 0.017 mm2. These features make the readout circuit with the pH sensor a promising solution for continuous monitoring of pH values in a wide range of applications such as real-time monitoring of physiological parameters and environmental monitoring.","PeriodicalId":235051,"journal":{"name":"2017 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127367043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to obtain the temperature values from the thermocouples more effectively, a PC-based multi-channel data acquisition and monitoring interface were developed by using LabVIEW graphical development platform. Measurements were carried out inside a TMM which has characteristics like human liver tissue. Temperature rise has been characterized for the different input ultrasonic powers (25 W, 38 W and 50 W) and frequencies (1,1 MHz and 3.3 MHz) and the time intervals applied (1 s, 2 s and 3 s).
