Pressure-sensitive conductive rubber has been investigated as sensitive material due to its good pressure-resistance characteristics. This paper presents a flexible tactile sensor with new structure. The sensing mechanism is based on body piezoresistive effect of conductive rubber filled by carbon black. To improve the sensor’s flexibility, there is a smart angle design in the arrangement of the wires in lower electrodes layer. Besides, the force model of the sensor has been described. The simulation results indicate the validity of 3-D force measurement of the sensor.

The assessment of the distribution of contact pressure on the meniscus is important in the elucidation of kinematics, etiology of joint diseases, and establishment of treatment methods. Compared with sensors widely used in recent years, pressure-sensitive conductive rubber sensors are easy to mold, flexible, durable, and resistant to shearing forces. This study is aimed at developing a rubber sensor for meniscal research and evaluating the pressure distribution after meniscal injury using porcine models. After confirming the reliability of the rubber sensor, contact pressure was obtained from the rubber sensor using the medial meniscus and femur of the porcine knee. Three test conditions of intact meniscus, radial tear, and meniscectomy were prepared, and a compressive load of 100 N was applied. After confirming the high reliability of the rubber sensor, the intact meniscus had the most uniform pressure distribution map, while the pressure in the meniscectomy model was concentrated in the resection region. The high-pressure region was significantly smaller in the intact group than in the radial tear models after 80 and 100 N ( P < 0.05 ). The rubber sensor captured the pressure concentration specific to each examination group and was useful for evaluating the relationship between the pattern of meniscal injury and changes in the biomechanical condition of the knee.
