Design of a wearable fall detection device

The accidents caused by fall, especially those happened upon the elders, have caught people's attention. In this article through researching the behavioral characteristics of fall, a kind of portable device based on pressure sensor is designed to achieve fall detection. This device is placed in the insole and uses a film type pressure sensor to collect human body foot pressure information in movement. Then a method that combines threshold analysis with the algorithm of support vector machine is used to analyze the foot pressure value and perform data processing, and judge whether the human body falls. Through experiment test verification, this device has a high reliability and accuracy in detecting fall.
