In medical care, it is essential to assess and manage acute painful conditions adequately. Heart rate variability (HRV) analysis is based on the acquisition of electrocardiogram (ECG), which is available from both patient monitor and wearable device. As HRV analysis can reflect autonomic nervous system activity which is unconsciously regulated, HRV analysis in ultra-short-term is getting attention...
Successful ECG monitoring algorithms often rely on learned models to describe the heartbeats morphology. Unfortunately, when the heart rate increases the heartbeats get transformed, and a model that can properly describe the heartbeats of a specific user in resting conditions might not be appropriate for monitoring the same user during everyday activities. We model heartbeats by dictionaries yielding...
Filtering of ECG signal is an essential step in ECG signal processing and analysis. Since ECG is a low amplitude biosignal, it is easily corrupted by external noises, and by the presence of other biosignals. The aim of filtering is to remove unwanted noise while preserving important characteristics of the signal. Various filtering techniques are available thus choosing the right filter for ECG denoising...
This paper presents an integrated wireless multiple sensors System-on-Chip (SoC) for healthcare including 3-lead ECG, bio-impedance (Bio-Z), and body temperature. To allow continuous and real-time monitoring, the SoC has included a multi-channel reconfigurable QPSK/BfSK transmitter (TX) to accommodate different power-constraint conditions. Fabricated in 130nm CMOS technology with a total die area...
Heart rate variability (HRV), a feature extracted from the heart rate signal, is commonly used for monitoring training loads, and fitness status within athletes. Various sensors can be used to ascertain HRV within athletes; two of which are considered within this investigation, namely PPG and ECG. We present methods for HRV collection and calculation using PPG, reducing HRV collection time requirement...
Early detection and monitoring of heart diseases increase human quality of life and this can prevent negative consequences. It is even more important because it can prevent sudden deaths. In today's technology, these operations can be done with telemedicine systems. In this work, appropriate methods have been proposed for telemedicine systems. The proposed system is of two classes and is based on...
Zebrafish have proven to be a crucial model for biological elucidations, especially heart-disease studies, owing to their remarkable regeneration capacity. Other than conventional methods, monitoring of electrocardiogram (ECG) has shown promising results recently; however, experiments were usually carried out with sedated fish, resulting in affected signals. In this work, wireless power transfer (WPT)...
This paper reports polymer-based apparatus with embedded flexible thin-film electrodes to monitor electrocardiogram (ECG) of zebrafish under mild or zero anesthesia. The apparatus were made of polydimethylsiloxane (PDMS) using the molding technique with molds formed by 3D printing. The system is capable of acquiring intrinsic ECG from multiple fish simultaneously, thus introducing a novel method to...
Firefighters have an increased risk for cardiac arrest while responding to incidences of significant magnitude. Current procedures in firefighting standards require several rehab activities such as measuring body temperature and electrocardiogram (ECG) for prescribed intervals during incidences. In this work, we developed a novel wirelessly powered, non-contact electrode (NCE) bio-potential sensor...
Common hospital monitoring set up includes nurses taking rounds throughout their assigned wards and checking the patient's vital signs. This process is very time consuming and prone to human errors, especially for large scale hospitals. As a solution, an Internet of Things (IoT) based pulmonary monitoring system was proposed. The system uses a single-lead heart rate sensor connected to a microcontroller...
Automated mental workload measurement is particularly important in safety-critical settings, such as in nuclear plants, aviation, air traffic control, shipping, and transportation, to name a few. As an example, recent statistics have suggested that 90% of the accidents in the transport industry are due to human factors. In this paper, we explore the potential of off-the-shelf wearable technologies...
Mobile service and wearable devices have become a new hotspot in recent year. People also pay more attention to the problem of e-health. Cardiovascular disease is a kind of serious disease that jeopardizes the health and life of human beings which has been widespread concern by academic and practice researchers. But the automated monitoring and prevention of heart disease, cardiovascular disease and...
This paper presents the design, implementation and test of a watch with the capability to measure multiple physiological signals, such as photoplethysmography (PPG), electrocardiography (ECG), and some physiological parameters extracted from PPG and ECG. Based on the PPG and ECG signals, the pulse rate and heart rate could be extracted respectively. Moreover, the pulse transmit time (PTT) could be...

The system uses the Wi-Fi 802.11 standard for wireless transmission of the data to an Android based mobile phone. The developed android smart-phone application displays the ECG information as well as the heart rate and...
Because sensor's and electrical techniques is progressing, some physiological instruments, like pulse oximeter oxygen saturation, electrocardiograph, body temperature, and heart rate monitor, have been developed as the wearable apparatuses. Now, the electrical blood pressure monitor all uses a cuff to measure the blood pressure. If the electrical blood pressure monitor wants to become a wearable apparatus,...
In this paper, we presented the design of low-cost, compact and wireless 12 lead Electrocardiogram analog front-end (AFE) system using TI ADS 1198. ECG analog front-end (AFE) systems are designed with ASICs or custom designed ICs which are too expensive to be used. The main components of a conventional ECG system include instrumentation amplifiers, operational amplifiers that implement active filters...
We have been developing a monitoring system to measure human information from human body. In the previous study, we developed a digital integrated circuit that enables acquisition of heart rate from ECG (Electrocardiogram) instead of MPU (Micro Processing Unit). This circuit reduced the power consumption of the MPU from 97 μW to 19.7 μW. In this research, we redesigned an MPU specialized for the human...
