The neuroscience has become more quantitative and information-driven science since emerging implantable and wearable sensors from macro to nano and computational tools facilitate collection and analysis of vast amounts of neural data. Complexity analysis of neural systems provides physiological knowledge for the organization, management and mining of neural data by using advanced computational tools...
With the rapid advances in sports technologies, athletes and sports coaches are constantly searching for improved performance assessment methods. Whilst athletic performances continue to improve, accurate training prescription and feedback is important to the consistency of the training outcome and maintaining the performance margin. Traditionally, the measurement of elite athlete performance is performed...
Terahertz frequency radiation lies between the millimetre and infrared regions of the electromagnetic spectrum (THz = 10^12 Hz, 1 THz corresponds to 4.14 meV). Terahertz radiation is non-ionising and able to probe intermolecular vibrations such as hydrogen bonds which occur naturally in biological systems. Additionally, terahertz imaging methods are able to obtain an axial resolution of around 40...
The key to a long healthy life is the adoption of a balanced diet and regular exercise. The paper describes the use of a Body Sensor Network (BSN) for real-time corrective feedback during the performance of an exercise routine. The feedback utility will log important parameters during an exercise session to allow one to keep track of fitness progress. Inclusion of vital sign sensors such as pulse...
A healthcare monitoring system with wireless woven inductor channels is proposed for body sensor networks. A sensor node with the proposed woven inductor channel consumes only 300 uW for sensing and 340 uW for communication with 1 Mbps data rate. The personal sensor controller consumes 8 mW, and the efficiency is 178 times than the previous work.
The HomeCare system is designed, developed and realized in our laboratory. It is remote monitoring system of base life functions which takes care about alone living elderly people. Not only standard monitored biosignals can give us the valuable information about the change in the state of the health of the monitored person. One of the possible monitored values can be the circadian cycle. The monitoring...
The sensing of biological signal is very actual especially bioelectrical signals are commonly measured for evaluating the health status of man. This article is focused on analysis and design of transducers for long term bioelectric activity measurement with the advanced capabilities in transmission of signal, time-impedance stability, low half cell voltage. The principle of electrodes is conducting...
A pedometer is popular as a quantitative evaluator of walking. However it may not measure the number of steps for elderly. In this study, we attempted to propose a step count algorithm based on a filter bank and a threshold processing to improve the accuracy of an accelerometer-type step counter for elderly. The waist acceleration signals during a self-paced walking were recorded form 74 participants...
Recent advances in wearable sensors, as well as wireless technology and mobile computing have fostered a dramatic growth of a new generation of monitoring systems that allow one to record physiological data from individuals carrying on daily activities in the home and outdoor environments. For many applications of wearable systems, there is typically a need for achieving stable contact of the sensing...
The authorspsila previous work discusses a policy-based approach for autonomous management of access control in body-sensor networks using the concept of a Self-Managed-Cell (SMC). This paper discusses an implementation on this approach that permits the specification and enforcement of policies that facilitate management of access control on the SMC resources allowing for the grouping of resources...
Unobtrusive and easy-to-use sensor devices are used for monitoring the health condition of people interested in adopting a healthier lifestyle. The collected data from body sensors and input from questionnaires are analyzed allowing to derive improvement plans and recommendations. With the help of feedback, coaching and motivation a closed-loop system approach is realized optimally supporting people...
This paper introduces a wearable microphone array system designed for health condition monitoring. In particular, the paper presents a novel wheeze signal detection method for wearable systems. The detection method is designed to operate at a sampling rate of 1000 Hz which is way below the typical sampling rate of 44 kHz for audio signals. The detection method is simple and involves only the estimation...
