IEEE 2016-2017 EMBEDDED PROJECTS ABSTRACT WEARABLE NONCONTACT ARMBAND FOR MOBILE ECG MONITORING SYSTEM ABSTRACT:- One of the best ways to obtain health information is from an electrocardiogram (ECG). Through an ECG, characteristics such as patients’ heartbeats, heart conditions, and heart disease can be analyzed. Unfortunately, most available healthcare devices do not provide clinical data such as information regarding patients’ heart activities. Many researchers have tried to solve this problem by inventing wearable heart monitoring systems with a chest strap or wrist band, but their performances were not feasible for practical applications. Thus, the aim of this study is to build a new system to monitor heart activity through ECG signals. It is considered to be a reliable, robust, and low-power-transmission ECG monitoring system. Bluetooth low energy (BLE) was used as the protocol for data transmission; this protocol was proposed to develop the low-power-transmission system. EXISTING SYSTEM:- The standard procedure in a hospital to measure an electrocardiogram (ECG) is to use a12-lead ECG. In a conventional12-lead clinical ECG system, electrodes are afﬁxed to speciﬁc parts of the chest, arms, or hands and legs. PROPOSED SYSTEM:- The proposed system has conductive electrodes act as sensors to obtain electrical signals from the human body. The conductive electrodes are ﬂexible, soft, and bendable. This prevents the user from feeling uncomfortable when using the device. The electronic circuitry in the proposed system consists of a Bluetooth 4.0 module, an ECG module, and a microcontroller. The Bluetooth 4.0 module was chosen to build a low transmission power system with active mode. The micro controller is used to convert the analog-to-digital for processing. ADVANTAGES:- Even though the effect of shirt thickness affects, the system still shows a clear peak or QRS wave. The experiment error rate is less than 10% than the conventional system available. DISADVANTAGE:- It requires a great deal of preparation and an expert to attach the electrodes to the patient’s body. It cannot be used for long-term measurement because of the limitation of the gel and complicated wiring. CONCLUSION:- A new wearable device for a healthcare monitoring system was proposed in this paper. The bio-signal that was measured in this system is an ECG signal. The proposed system was smart enough to overcome noise and detect useful information from the recorded signal. The results from these experiments show that the proposed system can still function even with different clothing thicknesses between the sensors and the skin and can also still function when the user carries out various daily living activities.
