This paper presents a wearable wireless ECG monitoring system based on novel 3-Lead electrode placements for long-term homecare. The experiment for novel 3-Lead electrode placements is carried out, and the results show that the distance between limb electrodes can be significantly reduced. Based on the new electrode position, a small size sensor node, which is powered by a rechargeable battery, is designed to detect, amplify, filter and transmit the ECG signals. The coordinator receives the data and sends it to PC. Finally the signals are displayed on the GUI. In order to control the power consumption of sensor node, a dynamic power adjustment method is applied to automatically adjust the transmission power of the sensor node according to the received signal strength indicator (RSSI), which is related to the distance and obstacle between sensor node and coordinator. The system is evaluated when the user, who wears the sensor, is walking and running. A promising performance is achieved even under body motion. The power consumption can be significantly reduced with this dynamic power adjustment method.

Accurate Energy Expenditure (EE) estimation is key in understanding how behavior and daily Physical Activity (PA) patterns a↵ect health. Mobile phones and wearable sensors (e.g. accelerometers (ACC) and heart rate (HR) monitors) have been widely used to monitor PA. In this paper we present a real-time implementation of activity-specific EE estimation algorithms, using an Health Patch and an iPhone. Our approach to continuous monitoring of PA targets personalized behavior and health status assessment, by automatically accounting for a person's cardiorespiratory fitness level (CRF), which is the main cause of inter-individual variation in HR during moderate to vigorous activities. The proposed system opens new opportunities for personalized health assessment in daily life, using ubiquitous devices.

“…This resulted in a wide adoption of Bluetooth for the wearable nodes, even with its limitations in terms of number of devices and high power consumption. The recent development of the Bluetooth 4.0 standard (also called Bluetooth Low Energy or BLE) was directly targeted to increase the energy efficiency and device connectivity of such protocol, with positive impact for wearable devices and BSNs for both consumer and medical applications [10]. However, it is not compatible with previous versions of the standard, having different stack layers and data exchange protocols and its low energy optimized profiles result in a reduced data rate.…”

Wearable devices enable the unobtrusive sensing of a wide range of human activities and the development of innovative applications. Wireless communication capabilities are one of the crucial features of networked wearable devices, since they set data exchange specifications and heavily affect the power consumption of the devices. In this paper, we investigate the use of the Bluetooth Low Energy (BLE) standard for the development of wearable devices with elevated data throughput requirements such as Health-related applications. In particular, we focus on the application-level and analyze the performance of different BLE modules when interfaced with a smartphone in single-and multislave configurations. Data throughput and power consumption are evaluated in relation to the parameters of the protocol and we present to the reader useful guidelines for an optimal integration of BLE in devices with data streaming capabilities.978-1-4799-8981-2/15/$31.00 ©2015 IEEE
