Development of Wearable Wireless Electrocardiogram Detection System using Bluetooth Low Energy

Abstract

Wearable monitoring devices can provide patients and doctors with the capability to measure bio-signals on demand. These systems provide enormous benefits for people with acute symptoms of serious health conditions. In this paper, we propose a novel method for collecting ECG signals using two wireless wearable modules. The electric potential measured from a sub-module is transferred to the main module through Bluetooth Low Energy, and the collected values are simultaneously displayed in the form of a graph. This study describes the configuration and outcomes of the proposed system and discusses the important challenges associated with the functioning of the device. The proposed system had 84% signal similarity to that of other commercial products. As a band-type module was used on each wrist to check the signal, continuous observation of patients can be achieved without restricting their actions or causing discomfort.

Wearable biosensors for human fatigue diagnosis: A review

“…Typically, a pair of conductive silver/ silver chloride electrodes are integrated into flexible three-electrode system to prepare wearable "tattoos" and "patches" based on screen printing technology. Then, wireless transmission devices, such as WiFi, 139 Bluetooth, 27 and NFC module, 140 been applied in glucose 74 and lactic acid detection. 143 The first wearable current biosensor was used for glucose detection.…”

Then, wireless transmission devices, such as WiFi, 139 Bluetooth, 27 and NFC module, 140 are integrated and transmit signals to the terminals (e.g., laptops, computers, and mobile phones) for continuous tracking and monitoring changes in electrical signals. According to the principle of signal change, the electrochemical response signal includes current, potential, and electrical impedance.…”

“…26 Then, the wearable biosensors feeds back the health data and physiological changes through wireless communication technologies, such as WiFi, Bluetooth modules, and near-field communication (NFC). 27 Although wearable biosensors were initially widely applied in the field of medical monitoring, but with the increasing emphasis on exercise fatigue, wearable biosensors are expected to play the vital role in military operations and sports monitoring.…”

A Non-Contact Compact Portable ECG Monitoring System

“…Moreover, these systems lack portability and were designed for very specific target populations, eliminating most of the general population. Even though there are several existing research projects that present portable ECG monitoring solutions with Bluetooth compatibility, the majority of these projects use conventional electrodes [11][12][13][14]. Lastly, previous implementations have encountered many issues with power consumption.…”

Enhancing Digital Filtering to Electrocardiogram Analysis: Butterworth Filter Application

“…In this study, it has a drawback, namely the absence of a memory card for data storage, the advantage of this tool is that it is made portable and compact so that it can be carried and used at various times. [19][3][20] [16]. In 2021, Rizki Aulia Rachman conducted a study about development of a low-cost and efficient ECG devices with IIR digital filter design.…”
