介绍了一种球形折叠电容式压力传感器阵列。通过将传感器阵列放置在人工关节球腔之间，以空间分辨率记录了不同球腔尺寸匹配、不同加载方向和不完全腔关节内的压力分布。分析了传感器阵列的性能，讨论了可能的应用领域以及其局限性。
A spherically folded capacitive pressure sensor array is introduced and characterized. By placing the sensor array between the ball and the cavity of artificial joints, the pressure distribution within the joint was recorded with spatial resolution for different size matching between the ball and the cavity, for different directions of loading and for joints with incomplete cavities. The performance of the sensor array is analyzed, possible fields of application as well as its limitations are discussed.
