Implication

Experimental study demonstrates a 24.4-fold power enhancement using square-prismatic interlocking interfaces in triboelectric nanogenerators, indicating strong utility for self-powered monitoring.

Key Points

To develop and evaluate an interlocking micro/nanostructure-enhanced triboelectric nanogenerator (ILMS-TENG) designed to maximize contact area, charge separation, and electrical output.
Fabricated interlocking micro/nanostructures using femtosecond-laser ablation on aluminum and nanoimprinting on complementary polydimethylsiloxane (PDMS) layers.
Evaluated interfacial geometries by comparing pyramidal, truncated-pyramidal, and square-prismatic surface patterns against a flat baseline control.
The square-prismatic ILMS-TENG produced peak outputs of 37.9 V, 3.40 μA, and 23.9 μW from a 1 cm² footprint, achieving a 24.4-fold power enhancement over the flat control.
The device charged a 4.7 μF capacitor to 5.39 V within 3 minutes and retained stable electrical output over 30,000 operating cycles while functioning as a self-powered vibration and pressure sensor.
