Recognition of early signs of deterioration in postoperative course could be improved by continuous monitoring of vital parameters. Wearable sensors could enable this by wireless transmission of vital signs. A novel accelerometer-based device, called Healthdot, has been designed to be worn on the skin to measure the two key vital parameters respiration rate (RespR) and heart rate (HeartR). The goal of this study is to assess the reliability of heart rate and respiration rate measured by the Healthdot in comparison to the gold standard, the bedside patient monitor, during the postoperative period in bariatric patients. Data were collected in a consecutive group of 30 patients who agreed to wear the device after their primary bariatric procedure.

PurposeThe present study aims to estimate the minimum number of accelerometer measurement days needed to estimate habitual physical activity (PA) among 6- (2010), 18- (2011) and 30- (2012) year-old participants, belonging to three population-based Brazilian birth cohorts.MethodPA was assessed by triaxial wrist-worn GENEActiv accelerometers and the present analysis is restricted to participants with at least 6 consecutive days of measurement. Accelerometer raw data were analyzed with R-package GGIR. Description of PA measures (overall PA, moderate-to-vigorous PA (MVPA), light PA (LPA)) on weekdays and weekend days were conducted, and statistical differences were tested with chi-squared and Kruskal-Wallis tests. Spearman Brown Formulae was applied to test reliability of different number of days of accelerometer use.ResultsDifferences between week and weekend days regarding LPA, MVPA and overall PA, were only observed among 30-year-olds. Higher levels of MVPA (p = 0.006) and overall PA (p0.70, two and three days of measurement were needed in adults and children, respectively. For LPA, a reliability coefficient >0.70 was achieved with five days in 6-year-old children, three days in 18-year-old young adults, and four days in 30-year-old adults. Considering MVPA, four days would be necessary to represent a week of measurement among all cohort groups.ConclusionOur results show that four and five measurement days are needed to estimate all habitual PA constructs, for children and adults, respectively. Also, among 30-year-old adults, it is important to make efforts towards weekend days measurement.

As a result, OEMs and aftermarket service providers are increasingly incorporating high-temperature accelerometers into their systems to comply with these regulations. The growing emphasis on safety, reliability, and quality assurance is thus expected to sustain the upward trajectory of the high-temperature accelerometer market.

From a regional perspective, Asia Pacific is emerging as the fastest-growing market, underpinned by rapid industrialization, expanding automotive manufacturing, and increasing investments in aerospace and energy infrastructure. North America and Europe continue to hold substantial market shares, supported by technological innovation and the presence of leading sensor manufacturers. Meanwhile, the Middle East & Africa region is witnessing gradual growth, primarily driven by investments in oil & gas exploration and energy projects. Each region exhibits unique growth dynamics, with local regulations, industrial activity, and technological adoption rates influencing market expansion.

Product Type Analysis

The product type segment of the high-temperature accelerometer market is broadly categorized into piezoelectric, piezoresistive, capacitive, and others. Piezoelectric accelerometers dominate the segment, owing to their superior performance in high-temperature applications and their ability to deliver accurate and stable measurements over extended periods. These sensors are widely used in aerospace engines, gas turbines, and industrial machinery, where temperature resilience and reliability are paramount. The ongoing advancements in piezoelectric materials, such as the development of high-temperature ceramics, are further enhancing the segment's growth prospects.

Piezoresistive accelerometers are gaining traction in applications that require high sensitivity and dynamic range, particul

Promoting physical activities is important for medical and functional recovery after stroke. Therefore, an accurate and convenient measurement of physical activities is necessary to provide feedback on functional status and effects of rehabilitative interventions. We assessed the feasibility, reliability, and validity of wearing accelerometers to monitor physical activities of stroke patients by estimating energy expenditure. This was a prospective observational quantitative study conducted in an inpatient rehabilitation unit. Twenty-four patients with subacute stroke were enrolled. They wore accelerometers on wrists and ankles for three consecutive weekdays. The feasibility was evaluated by daily wear-time. The test-retest reliability was determined by intra-class correlation coefficient. The validity was evaluated by comparing accelerometeric data to behavior mappings using Mann-Whitney U test, Spearman’s rho correlation coefficient (r) and Bland-Altman plots. Average wearing time for four accelerometers was 20.99 ± 3.28 hours per day. The 3-day accelerometer recording showed excellent test-retest reliability. For sedentary activities, wrist accelerometers showed higher correlation with direct observation than ankle accelerometers. For light to moderate activities, ankle accelerometers showed higher correlation with direct observation than wrist accelerometers. Overall, combined models of accelerometers showed higher correlation with direct observation than separate ones. Wearing accelerometers for 24 h may be useful for measuring physical activities in subjects with subacute stroke in an inpatient rehabilitation unit.

This dataset is from an air quality monitoring pilot in Maspeth, Queens between February and November 2024 as part of the NYC Office of Technology and Innovation's (OTI) Smart City Testbed program (https://testbed.cityofnewyork.us/). The Office of Technology and Innovation (OTI) partnered with the Department of Health and Mental Hygiene (DOHMH) to pilot Clarity Node-S air quality monitoring sensors (https://www.clarity.io/products/clarity-node-s) in order to evaluate their performance and generate real-time environmental data. The pilot also tested PAMARES model air quality improvement devices from StaticAir (https://www.staticair.com) to assess their effectiveness in reducing particulate matter in targeted areas. By combining continuous monitoring with physical air quality interventions, the initiative aimed to determine both the reliability of the sensor technology and the measurable impact of the air purification devices in urban settings.
