Arthritis is an intense or unremitting irritation ailment that influences the joints, connective tissues, muscle, ligaments, and stringy tissue. It is the leading cause of inability among individuals more than 50 years old in a developed country. Also, it tends to strike amid the most beneficial long periods of adulthood, regularly causing torment and deformation. It offers to ascend to tremendous healthcare expenditures and loss of work. With the existing system, there is a different size of FSR sensors used for foot pressure analysis. A sole with significant pressure points (2–9) was designed to analyze the foot pressure, but unfortunately, the foot size differs from one person to another person. So the single sole design setup cannot be used for all the persons. In the proposed method, a sensor array designed with single-layer carbon loaded polyethylene film was designed, and each sensor with sides 21 mm × 21 mm to form the 7 × 3 array pattern of the foot pressure pad. By using the array foot pressure pad, we can analyze the pressure points throughout the pad. Each of the sensors in the array is having a gap of 5 mm. The output analog signal acquired, and these electrical signals may result in preemptive of the knee problem.
