1. Introduction

Population aging problem is increasingly prominent, and the technology to help adapt to the aging has been widely concerned. Due to the aging of physiological structure and the decline of physical function for the elderly, the probability and frequency of accidental falls in the elderly are very high. The development of human fall detection technology has practical application value. In daily life, especially in wet places such as the kitchen, bathroom, and toilet, elderly people slip easily. If the elderly suffer from cerebral hemorrhage, heart disease, and other diseases, falls may also threaten their life. Therefore, the detection of falls is particularly important for the elderly. As one of the key components of intelligent devices, sensors have been widely used in the field of smart portability. With the expansion of the application range, more and more high requirements are put forward for the preparation of sensors with high sensitivity, high precision, and flexibility. At present, the fall detection based on wearable sensor is relatively accurate, which usually does not affect the detection results due to environmental changes. It is flexible and easy to use. It can also install sensors such as heart rate and blood pressure to monitor the physical condition of the elderly in real time. The multisensor attitude detection system combines multiple data together to get the prediction results and real-time output. Compared with the detection system based on a single sensor, the cooperative use of multiple sensors can further improve the accuracy and reliability of prediction.
