The evolving landscape of intelligent devices and toys demands seamless interaction, exceptional performance,
and visually captivating features. Triboelectric nanogenerators (TENGs) offer an eco-friendly solution for
generating electrical energy in smart toys and devices. This research introduces high-power and stretchable
triboelectric layers in various colors tailored for toys and wearable gadgets. Combination of the silicone rubber
with the ceramic powders, not only improved mechanical properties, but also provided vibrant colors. This
process enhanced the fracture strain and the toughness, and reduced the Youngâs modulus, so stretchability and
overall quality were increased. The best composite, the green layer, demonstrated outstanding attributes such as
a power density of 6.5 W/m2
, a fracture strain of 385 %, a toughness of 1.86 Mj/m3
, and a Youngâs modulus of
0.20 MPa. The green TENG, a sandwich format with an EGaIn electrode, was used for effective monitoring of
human body movements. Additionally, a highly efficient machine learning model has been developed for
identifying human motions with a remarkable accuracy of 98 %. The study highlighted the considerable power
density, voltage, and current exhibited by the colorful TENGs. By integrating these TENGs into circuitry, an
engaging toy was created that produces musical notes and displays corresponding pattern on a computer screen
when a colorful array was pressed. These colorful nanogenerators hold significant promise for battery-free toys
and wearable electronics.
