The smart pressure insole sensor is a new type of sensor developed based on our company's flexible and elastic sensing technology. Multiple capacitive pressure sensors are integrated into the insole, which use high-precision detection circuits to convert the compression at different positions of the insole during human movement into capacitance values, and then transform these values into pressure outputs. With the assistance of algorithmic programs, the magnitude and distribution of forces on the sensor can be visualized, allowing for the acquisition of various parameters during movement. This aids coaches and specialists in gait analysis and medical diagnosis, making it widely applicable in fields such as sports, smart healthcare, and medical rehabilitation.
