An ambulatory pulse oximeter system based on wireless sensor network is designed and integrated to the wearable sensor node. The system is developed to measure motion activities using pulse oximeter and triaxial accelerometer sensor during in motion. The input signals are pulse oximeter and triaxial acceleration signals which are acquired from a finger. However, motion artifact is originated a result...
ECG (electrocardiogram) is a test that measure electrical activity of heart. ECG is acquired from sensor situated on USN (ubiquitous sensor network) node. The measured ECG contains noise and motion artifact that need to be removed for proper diagnosis. Motion artifact is important noise to reduce because its frequency spectrum is overlap to ECG signal and causes misinterpretation while diagnosis....
An ECG and tri-axial accelerometer signal monitoring and analysis method for the homecare of elderly persons or patients, using wireless sensors technology was design and implemented. This paper presents a prototype of wellness monitoring system capable of recording, and analyzing continuous ECG and accelerometer data received from the human body. The system provides an application for recording activities,...
