New Horizons in Sensor Development

Abstract

Background Accelerometery and other sensing technologies are important tools for physical activity measurement. Engineering advances have allowed developers to transform clunky, uncomfortable, and conspicuous monitors into relatively small, ergonomic, and convenient research tools. New devices can be used to collect data on overall physical activity and in some cases posture, physiological state, and location, for many days or weeks from subjects during their everyday lives. In this review article, we identify emerging trends in several types of monitoring technologies and gaps in the current state of knowledge. Best practices The only certainty about the future of activity sensing technologies is that researchers must anticipate and plan for change. We propose a set of best practices that may accelerate adoption of new devices and increase the likelihood that data being collected and used today will be compatible with new datasets and methods likely to appear on the horizon. Future directions We describe several technology-driven trends, ranging from continued miniaturization of devices that provide gross summary information about activity levels and energy expenditure, to new devices that provide highly detailed information about the specific type, amount, and location of physical activity. Some devices will take advantage of consumer technologies, such as mobile phones, to detect and respond to physical activity in real time, creating new opportunities in measurement, remote compliance monitoring, data-driven discovery, and intervention.

Preliminary study for the assessment of physical activity using a triaxial accelerometer with a gyro sensor on the upper limbs of subjects with paraplegia driving a wheelchair on a treadmill

“…28,29 Hiremath et al previously stated that for estimating EE, subject body measurement parameters were also needed in addition to movement parameters. 13,14 There is a need to integrate research, 8 leading to a final evaluation of physical activity in daily life through verification of the validity and reliability of the activity estimation using a triaxial accelerometer with a gyro sensor. Among industrialized nations and regions, Japan has a low frequency of obesity, and its citizens are at low risk for developing heart disease.…”

“…The validation of such diverse products contributes enormously to the research and development of practical activities for promoting the health of all people from children to the elderly. 4,8 A series of reports based on studies of activity evaluation devices in wheelchair-using persons after SCI has been published in recent years. [9][10][11][12][13][14][15] Coulter et al 9 and Sonenblum et al 10,11 conducted several studies using multiaxial or triaxial accelerometers mounted on the wheels of wheelchairs.…”

A Study on Smart Campus Model in the Era of Big Data

“…[4] Besides, it has changed the way teachers and students interact with school resources and the environment, realizing the people oriented personalized service innovation. Compared with the digital campus, the Smart Campus has the characteristics as follows:…”

Évaluation et analyse de la performance par accélérométrie lors des mouvements de musculation

“…Les systèmes intégrés et sans fil apparaissent particulièrement intéressants pour l'analyse des gestes sportifs (Intille et al, 2012). On y distingue deux grandes approches qui présentent chacune des avantages et des inconvénients.…”
