Intelligent insole system based on capacitive pressure sensors

Abstract

The invention provides an intelligent insole system based on capacitive pressure sensors. The intelligent insole system comprises an insole and the flexible capacitive pressure sensosr and a signal collecting circuit system which are distributed in the insole; the signal collecting system comprises a sensor signal collecting module, a main control chip, a data storage module and a power source and wireless transmission module; the flexible capacitive pressure sensors transmit measured pressure signals of all the sole portions to the sensor signal collecting module, the sensor signal collecting module converts the pressure signals of multiple channels into digital signals and inputs the digital signals to the main control chip, the main control chip stores acquired pressure data into the data storage module or transmits the pressure data to the power source and wireless transmission module and analyzes and calculates human body state data including the heart rate, the weight, the walking postures, the walking numbers, the walking frequency and the walking speed, and the power source and wireless transmission module sends the pressure data to a mobile terminal. The intelligent insole system is reasonable in structure, wide in detection range, high in precision, short in responding time and capable of analyzing the human body states according to insole pressure distribution.

Description

technical field [0001] The invention relates to an intelligent sensor system for sole pressure, in particular to an intelligent insole system based on a capacitive pressure sensor for monitoring the distribution of sole pressure, belonging to the field of intelligent wearables. Background technique [0002] With the advancement of society, people's quality of life is gradually improving, and more and more people are beginning to pay attention to their physical condition, hoping to obtain more data about their own condition to evaluate their health. For medical staff, obtaining detailed physical data of patients can help to accurately diagnose and treat diseases. On the other hand, as the sensor technology becomes more and more mature, the volume of the components becomes smaller and smaller, making it possible for the sensor to be more conveniently integrated into the body-wearing objects. Wearable devices, but most products obtain human body data through the wrist, so the ...

Problems solved by technology

On the other hand, as the sensor technology becomes more and more mature, the volume of the components becomes smaller and smaller, making it possible for the sensor to be more conveniently integrated into the body-wearing objects. Wearable devices, but most products obtain human body data through the wrist, so the types of physical sign data that can be obtained are limited. In addition, due to the large degree of freedom of movement of wrist accessories, large external interference factors, and the complexity of hand movements, making The human body data obtained by the hand has low reliability and low precision, which has become a problem affecting the development of this type of wearable products
