| 초록 | Recently, a lot of studies for conductive fibers have attracted with development of wearable devices and electronics. Conductive fibers, which are highly adaptable to the morphologies of the human body, is very necessary for the development of wearable system, smart clothing, and textronics to detect various biological signals and human motions. Herein, we fabricated a conductive fiber-based sensor interconnected with hierarchical micro-hairy structures, with high stretchability (＜ 200%) and sensitivity for various stimuli (pressure, stretching, and bending). Two hierarchical hairy conductive fibers are twisted to fabricate the fiber-based sensor with multiple gestures distinguishability, which monitors distinct waveforms of electrical resistance signals retrieved from appliance of pressure, stretching, and bending. Self-assembled monolayer was formed on the surface of the sensor, which displays stable performance even under wet conditions. For practical applications, a smart glove wearable controller for virtual reality (VR) interface was demonstrated with a pressure and gesture-discernible sensor. |
