Energy harvesting and smart textile sensing application. (a) Capacitor charging curves using the triboelectric yarn of two different capacitors. A full-bridge rectifier was used to rectify the output. The inset shows the LED powered by the triboelectric yarn. (b) Arm motion sensing using the triboelectric yarn. The yarn was integrated into the lab coat by placing it under the armpit. The blue and red curves show, respectively, the Voc caused by a forward and backward arm motion. The direction of the motion is shown in the insets. (c) Demonstrating the haptic potential of the triboelectric yarn integrated on a glove. The yarn (5 cm in length) was attached to the index finger of the glove. (d) Force sensing sensitivity of the triboelectric yarn. A load cell was used to measure the applied force.
