Hi am shivaraj i would like to get details on wearable biosensors seminar report in ieee format ..My friend Bilal said wearable biosensors seminar report in ieee format will be available here and now i am living at GADAG and i last studied in the college TCE GADAG and now am doing BE 4 th i need help

The sensors and portable systems have evolved to the point where they can be considered ready for clinical application. The use of portable monitoring devices that allow the continuous or intermittent monitoring of physiological signals is critical for the advancement of both diagnosis and treatment of diseases. Portable systems are completely non-intrusive devices that allow physicians to overcome the limitations of ambulatory technology and provide a response to the need to monitor people for weeks or months.
Usually, they rely on miniature wireless sensors enclosed in patches or bandages or items that can be worn, such as a ring or shirt. The datasets recorded using these systems are then processed to detect events predictive of possible worsening of the clinical situations of the patient or are scanned to access the impact of clinical interventions.
It is a pulse oximetry sensor that allows continuous monitoring of heart rate and oxygen saturation in a totally discreet way. The device is in the form of a ring and, therefore, can be used for long periods of time without any discomfort to the subject. The ring sensor is equipped with a low-power transceiver that performs bidirectional communication with a base station and the charging date at any time.
Each time the heart muscle contracts, the blood is expelled from the ventricles and a pressure pulse is transmitted through the circulatory system. This pressure pulse when traveling through the vessels causes displacement of the vessel wall which is measurable at various points. Volume changes by the photoelectric method, the photo drivers are used. Abnormally photo resistors are used, for amplification purpose photo phototransistors are used.
The light is emitted by the LED and transmitted through the artery and the resistance of the photographic resistance is determined by the amount of light that reaches it. With each contraction of the heart, blood is forced to the extremities and increases the amount of blood in the finger. The optical density with the result that the transmission of light through the finger is reduced and the resistance of the photoresist increases accordingly. The photoresistor is connected as part of the voltage divider circuit and produces a voltage that varies with the amount of blood in the finger. This voltage follows closely the pressure pulse.
