Chennai: Elderly people often injure themselves when they collapse due to weak health condition or losing balance, but they fail to receive immediate care. R Dinesh Kumar, a final year student of electronics and communication engineering department of St Peter's Institute of Higher Education and Research, under the mentorship of G B Ramesh, has developed a wearable device to track abnormal movement of an individual.The designed S-Waist band is used to monitor the health condition of the old people by fixing it to them, which would serve as a wearable notification system to inform kin of the situation.
Dinesh says the device is used to find the abnormal body motion of the elderly people if they fall down in some place where the caretaker or relative may not be present at that moment. “In such a situation, the device can give the information to the caretaker as well as to the nearest hospital to safeguard them from the dangerous condition. Here we are also using the combinational integrated sensor system with MEMS sensors to sense the heart rate and the variation in the heart rate to give the exact result,” says Dinesh.
The QRS complex detection algorithm is used to identify the different condition of the heart functioning. Arduino software and the Energia software can analyse the detection of motion of the person. The MEMS sensor is miniature in size and gives the minute changes in the heart rate. It is also used to monitor the blood pressure and weight scales.
“The device can be used for elderly people and people with mental disorder. The information can be conveyed to the kin of the person wearing it through mobile phone. Manufacturers can be easily trained for production,” added Dinesh.
