开发了一种人造中空纤维结构作为MEMS新材料，并将其应用于新型织物触觉传感器。人造中空纤维是通过在弹性管表面均匀沉积金属层和绝缘层制成的。开发了一种特殊的旋转机构，用于在溅射过程中在管表面均匀沉积金属层。通过将人造中空纤维和典型的棉纱结合起来，制成了矩形织物触觉传感器，就像布料一样。该传感器可以通过测量人造中空纤维所有交叉点处的电容变化来检测接触力。还制造了两种不同类型的可穿戴触觉传感器手套，即补丁型和直接编织型，并证实这两种类型都可以通过测量电容变化来检测正常负载。
An artificial-hollow-fiber structure as a new material for MEMS was developed and applied to a novel type of fabric tactile sensor. The artificial hollow fiber was fabricated by uniformly deposited metal and insulation layers on the surface of an elastic tube. A special rotating mechanism for uniformly depositing a metal layer on the tube surface during sputtering was developed. A rectangular-shaped fabric tactile sensor was produced by combining artificial hollow fibers and typical cotton yarns, like a cloth. The sensor can detect a contact force by measuring changes in capacitance at all intersection points of the artificial hollow fibers. Two different types of wearable-tactile-sensor glove, a patched type and a direct knit type, were also fabricated, and it was confirmed that both types can detect a normal load by measuring the capacitance change.
