Wearable devices begin to integrate into the daily lives along with recent technology development. One of such important applications is to accurately monitor ultraviolet (UV) radiation received by the human body. To compensate for the localized monitoring area of existing personal UV monitoring devices, this paper proposes a reconstruction method to estimate the UV dose over the entire body based...
Step-by-step determination of gait parameters provides insight into the variability of specific gait patterns associated with frequent injuries in the lower extremities of adolescents and with geriatric syndromes of the elderly. Numerous methods have been developed for the step-by-step estimation of gait parameters, but most are expensive, obtrusive, inconvenient, and/or inaccurate. In this paper,...
Military working dogs (MWDs) are at high risk of heat strain both during training and missions. Body heat in a MWD increases due to work, and the primary means for reducing this heat are resting and panting. Body-worn sensors can enable monitoring of work level and respiratory rate in real time. They can thereby provide real-time objective indicators of thermal strain in MWDs. In this paper a system...
The headset mouse is an assistive technology created for individuals with limited to no mobility in their arms. Specifically, this device was created for persons with Amyotrophic Lateral Sclerosis (ALS) also known as Lou Gehrig's disease. The design utilizes a NeuroSky headset, which is used by reading EMG signals to implement mouse clicks using hard blinks and eyebrow raises. A gyroscope is used...
Load carriage was used as an experimental tool to evaluate the ability of an anatomically-based, two-mass model of the human body to predict vertical impact and peak forces during running from only four inputs: body weight (Wb), contact time (t¡), aerial time, (t¡), and lower-limb acceleration (a1). Simultaneous motion and force data were acquired from seven subjects during steady-speed trials (3...
Multimodal electrochemical method comprising open circuit potential and amperometric technique has been implemented to improve the specificity of the ethanol detection in a fuel cell sensor system. A miniaturized device with LMP91000 potentiostat and a processing unit has been constructed containing simple auto-calibration algorithm. The developed processing unit consist of a low power microcontroller...
Body sensors have a promising contribution to health promotion in many areas of daily life (telemedicine, corporate health care or recreational sports). However, the valid measurement of vital signs and kinematic data strongly depends on the signals' quality and the users' compliance (proper usage). Although, there is a lot of research work concerning accuracy and calibration of wireless body sensors...
The purpose of this study is to develop a localized muscle fatigue detection system to assist patients during isometric exercise. A mobile device is fastened to the forehand of the subject to receive electromyography (EMG) signals sent wirelessly from BITalino board. Our proposed system then uses surface electromyography (sEMG) technique to capture electromyography (EMG) signals that are processed...
Several different factors have been proposed to contribute to the development of chronic low back pain (LBP). Specifically, researchers and clinicians have proposed that impairments of low back posture and movement, particularly during functional activities, are important to address during intervention. However, objective measures of posture and movement are typically only measured in the laboratory...
Ultra wideband (UWB) radio technology has been shown to have tremendous potential to support certain Brain Computer Interface (BCI) applications. To implant UWB transmitters inside a human brain to transmit ECoG signals from the neurons in the brain (collected by bio-implantable electrodes) to stimulators residing on the spinal cord or on muscles at different parts of the body (non-invasive), almost...
The main purpose of this study is to find possible relationships between the smoothness of hand function during laparoscopic ventral hernia (LVH) repair and psychomotor skills in a defined virtual reality (VR) environment. Thirty four surgical residents N = 34 performed two scenarios. First, participants were asked to perform a simulated LVH repair during which their hand movement was tracked using...
This paper will focus on bed angle detection in hospital room automatically using the latest Kinect sensor. The developed system is an ideal application for nursing staff to monitoring the bed status for patient, especially under the situation that the patient is alone. The patient bed is reconstructed from point cloud data using polynomial plane fitting. The analysis to the detected bed angle could...
The common marmoset is emerging as an important transgenic model for improving the understanding of the underlying neurological basis of many brain disorders. Automated systems for quantitative monitoring of marmoset behaviors in naturalist settings over long period of time are needed to facilitate this process. This paper presents the preliminary work toward building a novel multimodal acquisition...
In the Wireless Body Area Network (WBAN), radio propagations from devices that are near or inside the human body are composite and unique contrasting with the different environments since the human body has a composite shape comprising of various tissues. Along these lines, channel models are unique in relation to the ones in alternate situations. We present a channel modelling of a situation imitating...
Leveraging miniaturized sensor and monitoring technology integrated in easy-to-wear wristband wearables represents a great opportunity for advancing Resilience and Mental Health of e.g. employees that experience high workload. Therefore, it is important to gain insights into the reliability of such technology before far reaching conclusions can be drawn and interventions can be developed. To that...
