“…To eliminate the uncomfortable feeling of the electrodes and cables, other methods using dry electrodes have been proposed [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The electrodes and wires in such methods are made of conductive textile [1][2][3][5][6][7][8][9][10][12][13][14][15][16] or conductive ink [4,11], and are embedded in a shirt or belt. Such a shirt is called a smart shirt and the biological signals are measured for a person wearing the shirt [1][2][3][4][5][6][7][8][9].…”

“…The belt is wound around a subject's body and measures biological signals [10][11][12][13][14][15][16]. Smart shirts and belts measure various biological signals, including ECG signals [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], electromyogram (EMG) signals [1,2,7,11], and signals of the respiration rate [1,7,[14][15][16] and other body properties [1,6,7,11,12,14,15]. We consider an ECG measurement made using smart shirts and belts.…”

“…Different methods of the ECG measurement employ bipolar leads, unipolar leads, standard limb leads, and unipolar precordial leads. Almost all existing smart shirts and belts adopt unipolar leads to measure the ECG signal, with the use of three electrodes being the simplest method [2][3][4][5][6][7][10][11][12][13][14][15][16]. Unipolar leads allow the measurement of the signal of a simple ECG signal but cannot be used to measure the signal of a detailed ECG.…”

Abstract:The Holter monitor is used to measure an electrocardiogram (ECG) signal while a subject moves. However, the Holter monitor is uncomfortable for the subject. Another method of measuring the ECG signal uses a smart shirt. We developed a smart shirt that has six electrodes on the chest and can measure a detailed ECG, obtained with unipolar precordial leads. The electrodes and wires of the shirt are made of conductive ink that is flexible and stretchable. The smart shirt is stretchable and fits the body well. However, because of the gap between the smart shirt and the body, electrodes V1 and V2 do not touch the body consistently. We developed a conductive foam block that fills this gap. We investigated the characteristics of the conductive foam block, and measured ECG signals using the smart shirt. The electrical resistance of the conductive foam block was reduced by pressure. This characteristic could be utilized to measure the ECG signal because the block was pressed by the body and smart shirt. We could measure the ECG signal using the smart shirt and blocks OPEN ACCESSFibers 2015, 3 464 while the subject walked and could detect peaks of the ECG signal while the subject jogged slowly.

“…This technology can be used for realization of wearable textile electrodes for ECG sensor, which can be part of standard clothing [3]. However, despite the great advances in this area, current works on this subject do not include the complete characterization of the electrode, nor the electrical model, which makes it difficult to fully understand the behavior of such electrodes.…”

Electrocardiograph signals (ECG) are one of the most important parameters used for monitoring the human physiological state. Nowadays, the research works using fabric conductive textiles for ECG are focusing on reliable and wearable systems. However, a complete characterization of textile electrodes is required to integrate it in standard clothing. Therefore, this work is devoted to the electrical characterization of electrodes based on conductive textile for an ECG system that monitoring the different human positions and also a comparison using the traditional silver (Ag/AgCl) chloride electrodes is presented allowing to demonstrate that ECG measured signal with these devices is proper for applications in wearable health monitoring.

The work aims to present an ultra-low power Electrocardiogram (ECG) on a chip with an integrated Fuzzy Decision Making (FDM) chip for Wireless Body Sensor Networks (WBSN) applications. The developed device is portable, wearable, long battery life, and small in size. The device comprises two designed chips, ECG System-on-Chip and Fuzzy Decision Maker chip. The ECG on-chip contains an analog front end circuit and a 12-bit SAR ADC for signal conditioning, a QRS detector, and relevant control circuitry and interfaces for processing. The analog ECG frontend circuits precisely measure and digitize the raw ECG signal. The QRS complex with a sampling frequency of 256 Hz is extracted after filtering. The extracted QRS details are sent to the decision maker chip, where abnormalities/anomalies in patient's health are detected and an alert signal is sent to the patient via wireless communication protocol. The patient's ECG data is wirelessly transmitted to a PC, using ZigBee or a mobile phone. The chip is prototyped and employed in a standard 0.35µm CMOS process. The operating voltage of Static RAM and digital circuits and analog core circuits are 3.3 Volts and 1 Volt, respectively. The total area of the device is about 6 # and consumes about 8.5µW. Small size and low power consumption show the effectiveness of the proposed design, suitable for wireless wearable ECG monitoring devices.
