Examples of circuits and their technical features are provided for each stage of the bioamplifier development. This review traces the evolution of bioamplifiers, starting from circuits on vacuum tubes and discrete transistors through circuits on operational and instrumental amplifiers, and to combined analog-digital solutions on analog front-end integrated circuits. Since the vacuum tube era, engineers and designers of bioamplifiers for recording electrophysiological signals have been trying to achieve similar objectives: increasing the input impedance and common-mode rejection ratio, as well as reducing power consumption and the size of the bioamplifier. The past century has seen the ongoing development of amplifiers for different electrophysiological signals to study the work of the heart. The application is also able to display the recorded values in the form of a graph to help determine the state of health of the user over a period of time. An alert is sent to confidants via email or SMS when these values are abnormal.

These sensor values are transmitted to an android device via Bluetooth and are managed by the android application. The wearable unit contains sensors to monitor the heartrate and body temperature of the user, which are displayed on an LCD screen. Patient Medical Emergency Alert System (PMEAS) consists mainly of two components, a wearable hardware unit and an android application. In this paper, a system to monitor heartrate and body temperature of a user and alert the user when these values are abnormal is proposed. The ability to monitor these two vital signs is key to ensure proper healthcare is delivered early. Heartrate and body temperature are two very important vitals related to the health of a person. Healthcare and health of people is an important need of the human population.
This work with the intelligent health care system provide an efficient medical service ,by collecting and recording the informant that include heart rate, ECG, temperature and spo2 that enable the doctor to monitor his patient with flexibility and confidence. The data of patient are sent to the web server to be stored in the database and view the data on the web page anywhere and anytime using smart devices and alert the doctor to any abnormal state. The WI-FI technology is utilized as a communication tool to allow transmission the data remotely. With the system proposed, the doctor can save work time to visit the patients that responsible about them and any facilitates monitoring the huge number of patients. The focus of this paper is to implement an intelligent health care system based on internet of thing (IOT) for the measurement of the vital signs like pulse rate, temperature, spo2, ECG, using (ESP32 div kit v1) for wireless wearable sensor controller and raspberry pi 3 as a server.
