IoT based monitoring of foot pressure using FSR sensor

Analysis of foot plantar pressure distribution is an important factor considered today in the field of healthcare as well as in sports world. Lower body physical rehabilitation therapies are associated with sports world. To avoid long-term damage to the affected part and to accelerate the recovery period, it is necessary to keep an eye on the patient regularly following his/her rehabilitation activities not only in the hospital but also at home. Multiple techniques have been developed for quantitative gait analysis but comparatively these systematic process fails as it measures static or dynamic process for very short duration of time and space. In the proposed system, an electronic insole system is designed in a shoe using force sensing resistor (FSR) sensor that monitors pressure wirelessly, thus saving the information in an array of sensor network for transferring data into CPU. Thus considering the information available used for further study purpose. Four sensors are placed, one at the heel, one at the lateral part, one at the metatarsal head and one at the anterior. The plantar pressure is used to analyse pressure distribution. The signal from the pressure sensor will be processed by microcontroller and sent to mobile via Bluetooth module. With the help of Internet-of-Things (IoT), when the signal goes beyond the limit the notification will be sent to patient consulting the doctors/physiotherapist so that immediate action can be carried out further. The proposed system will help the doctors/physiotherapist as well as person to monitor his health using smart shoe. The device can help the clinician and the patient a tool to monitor and receive condition feedback.
