A 2.4-GHZ ENERGY –EFFICIENT TRANSMITTER FOR WIRELESS MEDICAL APPLICATIONS ABSTRACT: A 2.4-GHz Energy-Efficient Transmitter For Wireless Medical Applications, so many medical systems based on wireless communication techniques have been developed to improve human health, such as wireless body sensor networks (WBSNs). The human body worn sensor nodes are used to monitor vital signs, such as temperature, heart rate, and electrocardiogram (ECG) in WBSN. In addition, the function of the sensor nodes can be expanded to medical treatments, such as drug delivery and nerve stimulation. After the biomedical information acquisition, the signal will be preprocessed and stored the information will be transmitted by the RF transceiver to the portable base station. The sensor nodes also receive some control commands from the base station remotely. The main purpose of this project is to monitor human’s health in a wireless manner. In our project temperature sensor, heartbeat sensors, etc are fixed on the human body for inertial sensing. The temperature sensor will sense the human temperature. MEMS sensor will sense the vibrations of any fractured operated part Pressure sensor will sense the Blood pressure, Heart Beat sensor will sense the heart beats of the patient. Corresponding Sensed signals in the form of physical values are converted into digital values using analog to digital converter which is given as input to the microcontroller. In this controller we are keeping some threshold value if determined value is exceeds buzzer will indicates that the corresponding person gets conscious. Those sensors outputs have been displayed in cell phone using GSM to update the patient’s family members for updation.Similarly, the sensor values are displayed in PC through Zigbee for doctor to analyze on a wireless manner.
