A wearable wireless ECG monitor prototype design : a report submitted to the faculty of the Milwaukee School of Engineering in partial fulfillment of the requirements for the degree of Master of Science in Engineering / by Hongxu Zhang. by Zhang, Hongxu, author., Kumpaty, Dr. Subha, Acharya, Dr. Kishore, committee member, Shimek, Gary, Milwaukee School of Engineering [Milwaukee School of Engineering], [2016] Subjects Electrocardiography   Heart Diseases -- diagnosis   Wireless communication systems in medical care -- Design and construction   Wearable computers -- Design and construction.   Android (Electronic resource)   MSE Project. Description:  82 leaves : illustrations, some of which are in color ; 29 cm Contents:  Introduction -- Design -- Implementation -- Human testing -- Conclusions -- Appendix A. STM32 code -- B. Android application code. This report describes a project in which a wearable wireless monitoring system was developed from discrete external components and a custom PCB (printed circuit board). The purpose of the device is to enable a user to monitor their ECG (electrocardiogram) signal on their Android mobile phone. The device was designed to provide users wearing comfort and monitoring convenience. The monitor itself consists of two external electrodes, a moveable charger, an AD8232 integrated signal conditioning block for ECG and other biopotential measurement applications, as well as a central PCB that contains a microcontroller STM32 and Bluetooth Module for data processing and transmission. The system can be configured to work in EMS (Emergency Monitoring Services) for ECG and Arrhythmia Monitoring. The raw signal captured by these two electrodes is filtered and amplified by the AD8232 block that contains a 0.5-30 Hz bandwidth filter and amplifier bundles with a total gain of 600. The STM32 microcontroller is utilized to convert the analog data to digital data, to eliminate 60 Hz of noise resulting from the power, and to communicate with the GPIO (General Purpose I/O). The Android application was developed with Android Studio to monitor the ECG signal on a mobile phone in real time. The device was tested in two stages on the author of this report. In the first stage, the analog signal from the AD8232 block was successfully tested and displayed on an oscilloscope. In the second stage, the ECG signal was successfully streamed to the Android application, and was displayed with greater accuracy. Therefore, the main goal of the project was achieved: a working wearable wireless heart monitoring system featuring on Android application. Possible future research activities associated with this project include the development of an Apple iOS application. Such an application would entail the development of additional algorithms, resulting in additional functionality. This additional functionality could include a more accurate signal, a HR (heart rate) display, an alert to notify users when an arrhythmia occurs, as well as the option to save data to a cloud server, which can be shared with others.
