Radio frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored info. Passive tags collect energy from a nearby RFID reader interrogating radio waves. Active tags haves a local power source (such as a battery) and may operate hundreds of meters from the RFID reader.
Unlike a Bar code, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object. RFID tags are used in many industries for eg, an RFIOD tag attached to an automobile during production can be used to track its progress through the assembly line; The RFID pharmaceuticals can be tracked through warehouses; and implanting RFID microchips in livestock and pets allows for positive identification of animals.
Improving the efficiency of the Healthcare systems are the most challenging goals for today’s society. A patient’s physiological info is managed and recorded for a long time using wearable sensors. This system is expected to reduce cost, increase the quality of life and enrich the user’s experience. According to the WHO standard, 60% of the population of India is affected by chronic and cardiovascular diseases. This system reduces the headache of the patient to visit the doctor every time he or she needs to visit the doctor. Doctors and hospitals could make use of real time data collected on the cloud platform to provide fast and efficient solution. The tags can be either passive, active or battery assisted passive.
The sensors continually collect the info from the patient’s body to get the patient details. In case of an emergency these wireless devices can distantly report the physical condition of the patient to his doctors or his relatives. In such a condition the doctors can respond with emergency solutions and services to aid them. There are different sensors attached to a patient’s body to measure different parameters like EEG, blood pressure, body temperature, blood glucose ,ECG and motion.
