Abstract:

BACKGROUND: Body of the elderly changes along with aging. Pathological changes of acute and chronic diseases may influence sense input, central nervous system function and skeletal muscle strength coordination, leading to extremely high probability on tumble. In daily life, falls of the elderly may cause serious consequence.
OBJECTIVE: To design a tumble detection device based on three-dimensional acceleration technology.
METHODS: A tumble detection device was designed based on the three dimensional acceleration and ZigBee wireless communication technology. The collected acceleration signals were sent to PC by ZigBee wireless communication for data analysis and processing.
RESULTS AND CONCLUSION: Results of experiments show that this equipment can achieve an accurate judgment on tumble occurrence, and is able to classify the type of tumble, so the elderly may obtain timely medical aid after tumbles. Moreover, it provides information for doctor to judge the health of older persons.
