摘要:

The functionalized conductive polymer is a promising choice for flexible triboelectric nanogenerators (TENGs) for harvesting human motion energy still poses challenges. In this work, a transparent and stretchable wrinkled poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) electrode based TENG (WP-TENG) is fabricated. The optimum conductivity and transparency of PEDOT:PSS electrode can reach 0.14 kΩ−1 and 90%, respectively, with maximum strain of 100%. Operating in single-electrode mode at 2.5   Hz, the WP-TENG with an area of 6 × 3 cm2 produces an open-circuit voltage of 180 V, short-circuit current of 22.6 μA, and average power density of 4.06 mW m2. It can be worn on   the wrist to harvest hand tapping energy and charge the capacitor to 2 V in 3.5 min, and then drive an electronic watch. Furthermore, the WP-TENG as the human motion monitoring sensor could inspect the bending angle of the elbow and joint by analyzing the peak value of voltage and monitor the motion frequency by counting the peak number. The triboelectric mechanism also enables the WP-TENG to realize high-performance active tactile sensing. The assembled 3 pixel × 3 pixel tactile sensor array is fabricated for mapping the touch location or recording the shape of object contacted with the sensor array.
