“…Biomedical data were measured using a smart jacket with integrated sensors (skin temperature and movement data on the hand, temperature and humidity outside and inside the jacket) 16 , 18 ) in addition to a custom-made sensor belt (heart rate, skin temperature, air humidity and temperature on the chest/back) 19 ) . For reference, distributed skin temperature and environmental temperature and humidity were measured using commercially available reference sensors.…”

This study investigated the usefulness of continuous sensor data for improving occupational cold stress assessment. Eleven volunteer male subjects completed a 90–120-min protocol in cold environments, consisting of rest, moderate and hard work. Biomedical data were measured using a smart jacket with integrated temperature, humidity and activity sensors, in addition to a custom-made sensor belt worn around the chest. Other relevant sensor data were measured using commercially available sensors. The study aimed to improve decision support for workers in cold climates, by taking advantage of the information provided by data from the rapidly growing market of wearable sensors. Important findings were that the subjective thermal sensation did not correspond to the measured absolute skin temperature and that large differences were observed in both metabolic energy production and skin temperatures under identical exposure conditions. Temperature, humidity, activity and heart rate were found to be relevant parameters for cold stress assessment, and the locations of the sensors in the prototype jacket were adequate. The study reveals the need for cold stress assessment and indicates that a generalised approached is not sufficient to assess the stress on an individual level.

“…The prototype multisensory system consists of two types of sensor modules described in previous publications, one unit of IsenseU-HR+ [15] and six units of IsenseU-Move+ [16] connected to a small computer (Odroid-U3) that controls, synchronises and logs sensor data. The IsenseU-HR+ (weight 35 gram (75 gram including belt), size 7.7x4.6 cm) calculate heart rate based on ECG data (250Hz), skin temperature on the chest (every 3rd second), in addition to triaxial accelerometer and gyroscope data (20Hz), and transmits data wirelessly using Bluetooth 2.1.…”

Commercial systems utilizing data from inertial measurement units (IMUs) to analyse movement patterns have not yet been adapted to monitor daily training in cross-country (XC) skiing. The main purposes of this study are to investigate: 1) the feasibility and potential of a multi-sensor system consisting of a heart rate sensor, Global Navigation Satellite Systems (GNSS) data and seven IMUs placed at multiple locations on the body for outdoor XC skiing, and 2) the validity of employing hard decision rules based on the correlation between arms and legs for detecting subtechniques in classical XC skiing. All sensor data were synchronously sampled and synchronized with GNSS data from a commercially available sports watch while XC skiing on varying tracks, from amateur skiers and world-class athletes. An algorithm based on the correlation of the angular velocity of arms and legs was developed to detect the three main classic sub-techniques, diagonal, double poling with a kick and double poling. Other sub-techniques were classified as miscellaneous (0−20%). The system is shown to work well outdoors on snow during different conditions, and the implemented algorithm was validated by video analyses to detect the three sub-techniques with a sensitivity of 99-100%. This study is the first to detect and link sub-techniques in XC skiing to GNSS data, thereby associating the detection and distribution of sub-techniques to different terrains. Such information gives insight on technical and tactical aspects of skiers' daily training and competitions, thereby providing a tool for coaches and athletes.

Abstract. In this paper, we proposed a novel approach to monitor the vital signs based webcam for home telemedicine applications. This approach can continuously monitor the vital signs without wearable sensors. It uses the real time video processing algorithm to obtain the instantaneous heart rate(HR) and respiration rate(RR). Furthermore, the heart rate variability (HRV) was analyzed by power spectral density (PSD) estimation using the Lomb periodogram. Experiments in different scenarios were performed to verify the efficacy of the proposed noncontact monitoring vital signs based on webcam. The real time experimental system can be used to measure the instantaneous HR and RR, at the same time the low frequency and high frequency components were extracted. All experimental results show that the proposed concept can be applied to the home telemedicine in the future.
