Stretchable Triboelectric Textile Composed of Wavy Conductive-Cloth-PET and Patterned Stretchable Electrode for Harvesting Multi-variant Human Motion Energy

Triboelectric textile with wearable property and feasibility of large area preparation has presented great prospect in effectively collecting energy from human body motion to provide power supply for diversified wearable electronics. Here, we report a stretchable triboelectric textile (STET) composed of wavy conductive-cloth-PET and patterned stretchable electrode as basic knitting units, which can achieve multi-variant energy harvesting with low cost and well comfort. The STET display excellent output performances due to diversified working principles containing contact-separation and contact-sliding modes. Interaction between the knitting units can generate open-circuit voltage with a peak-to-peak value of 350 V and instantaneous peak power of 1 mW, the stretched-released STET produces peak voltage of 32 V, while tapping the STET with cotton twice contact-separation movements generate improved peak voltage and current. To prove the potential application, the STET is fixed onto different positions of hum...
