Abstract
Description
Technical field
[0001] The present invention relates to an intelligent orthopedic insole. In particular, the invention relates to an insole with integrated sensors for recording foot-related load and movement data and for supporting the adaptation and correction of foot function. State of the art
[0002] Common orthotic insoles are often custom-made and manufactured in specialized facilities. These solutions are time-consuming and expensive, and generally do not allow for continuous monitoring of foot condition during daily use. Furthermore, conventional insoles usually have a static function and cannot adapt to changing load or movement patterns. Object of the invention
[0003] The object of the invention is to provide an orthopedic insole that can be used without complex individual adjustments and enables continuous recording of load and movement information of the foot. Furthermore, the insole should offer adaptive support for foot function and improve user acceptance. Solution to the task
[0004] The task is solved by an intelligent orthopaedic insole according to the patent claims. The insole has an integrated sensor system comprising several pressure sensors (1), temperature sensors (2), and motion sensors (4). The sensors are arranged within the insole to detect load conditions and movement patterns of the foot. Furthermore, at least one actuator, in particular a vibration actuator (3), is provided to give the user haptic feedback. The insole also includes a control unit (6) designed to process the acquired sensor data. A wireless interface (7) enables the transmission of the sensor data to an external terminal. The insole has a multi-layered structure that combines wearing comfort, structural stability, and functional integration of the sensors.Optionally, microfluidic chambers (5) can be provided to adjust the pressure distribution. Advantages of the invention
[0005] The invention has the following advantages in particular: • Continuous recording of load and movement information of the foot • Improved support for the adjustment and correction of foot function • Increased user acceptance due to comfortable and integrated design • Ability to use in everyday life without complex individual adjustments • Flexible expandability through external devices Application areas
[0006] The invention is particularly suitable for orthopedic, preventive, and comfort-related applications. It can be used to support foot function in everyday situations where relief, adjustment, or monitoring of foot load and movement patterns is desired. Brief description of the drawings
