摘要：

It is necessary to recognize the human knee movement for patients with knee joint pain (arthritis) and also in patients' under-recovery. Pressure variation around the knee joint is considered as a piece of vital information to address the problems in knee joint. Wearable sensors are the generally appropriate procedure for this. In this work, sensing mechanism are arranged in a suitable patella package using CNF (Carbon Nano Fiber) and TPU (Thermoplastic Polyurethane) based nanocomposite piezo-resistive (20% w/w) sensor film with bulk resistivity of 192 omega-cm. It is further tested for its suitability for monitoring the change in the resistance due to pressure variation during knee movement. The reliability of voltage variation under rehashed compressive stacking lab experiments shows significant usage for this piezoresistive film. Hence, it can be effectively utilized for signal acquisition application for knee movement monitoring in the arthritis patients.
