Measures of heart rate are widely used to assess the health state of human in clinic. Tranditional method uses eletrodes touching the body to monitor electrocardiography (ECG) .A micorwave sensor was disscused to remote sense the heart rate without touching human body. Comparison of heart rate derived from the microwave sensor and ECG demonstrated that there were no significant differences, which suggested this sensor may prove a practical alternative to ECG for heart rate measurement.

The proposed sleep security and energy-saving device with heart rate as the turning point of body, provides a solution for some of the problems existing in the modern family life. Such as electrical appliances may waste too much electricity, or bring safe hidden trouble. The device is originated from the medical phenomenon which is when the body is sleeping. Human heart rate will slow down to a certain extent than normal. If the heart rate has difference with the normal levels in a period of time, the device will make a judgment that disconnects the electrical appliances.

Photoplethysmography measures vital signs through to extraction of signals from the body. The paper explains the technique for extraction of pulse rate from the videos for three color channels namely; red, green and blue. The DMIMS database is used for experimentation which consists of total 720 videos out of which 25 videos are used for analysis. The results presented in this paper depict that our algorithm works best for blue channel followed by green and then red channel. The main focus of paper is to extract pulse rate from the recorded video and compare the output for different channels and find the best channel for heart rate extraction.

The heart is one of the most important organs of the human body. It acts as a pump that circulates the blood, carrying oxygen and nutrients in the body to keep it functioning. Today, several advanced methods have emerged in the field of medicine, which aim to improve the efficiency of the medical services.  And these new methods are akin to a technical identification of the disease with high precision, a new radiological technology and a fashionable identification of medical health. In the medical department, several studies are underway to provide the latest technologies. There are some people suffer from bradycardia or tachycardia. Might their lives are in danger if the patients are alone. In this research paper, a framework is developed to solve and improve equipment that constantly monitors heart rate and prevent casualties due to the heart related problems. The research is done to reduce deaths resulting from irregular heartbeat.  Uneven heart rating which is greater than determined value raises an alert and messages with heart readings are sent to doctors and other related persons. It also provides this information via Bluetooth and exposes it in the Arduino application platform to ensure the information is not corrupted and recalled on demand. Doctor can remotely access the sensing element. For this reason, Arduino-based sensors dealing with these problems are used in this smart application. An Arduino-based sensing element evaluates the patient's heart rate. Coupled with this, doctors remotely follow the patient and take quick action to save patients life.

A cozy room should adjust its environment based on the condition of its occupants since it will indirectly affect the moods and body conditions of people inside. This study aims to develop a system for monitoring the human body condition using paired sensors on the Arduino Lilypad. The system will send the sensors data to the Raspberry Pi3 via Bluetooth to automatically control the electronic device inside the room based on the occupant body condition. The developed system will automatically turn on or turn off the electronic device when the body temperature or the heart rate is higher than the specified threshold value. Keywords: Lilypad, Raspberry, body sensor

Blood (blood plasma) is a special all-pervading substance, functionally co-tuning all organs, tissues and cells of the body. To some extent blood is similar to the Ether of the ancients. In addition to performing house-keeping functions, blood is a medium for the transfer of huge amounts of information, which is continuously exchanged between all the compartments and structures of the macro-organism and its microbiome. This information is transmitted mostly in the form of chemical signals (peptides, micro-RNA, extracellular DNA, the products of the microbiome, antibodies, etc.), the totality of which controls lots of biological processes. Blood is not only a controlling, but also a reflecting environment: dynamic changes in the composition of this environment carry information about the smallest changes in the state of individual populations of cells, tissues, organs and the body as a whole. The prospects of practical using of information about the state of the organism, transmitted by blood and reflected in individual’s serum immunoreactivity profiles are analyzed.

Heart Rate Measurement

Continuous monitoring of heart-rate is expected to lead to early detection of physical discomfort. In this study, we propose a non-contact heart-rate measurement method which can be used in an environment such as driver heart-rate monitoring with body movement. The method is based on the electric field strength transmitted through the human body that changes with the diastole and systole of the heart. Unlike conventional displacement detection of the skin surface, we attempted to capture changes in the internal structure of the human body by irradiating the human body with microwaves and acquiring microwaves that pass through the heart. We first estimated the electric field strength transmitted through the heart using three receiving sensors to reduce the body movement effect. Then we decomposed the estimated transmitted electric field using stationary wavelet transform to eliminate significant distortion due to body movement. As a result, we achieved an estimation accuracy of heart-rate as high as 98% in a verification experiment with normal body movement.
