Flexible and Transparent Nanogenerators Based on a Composite of Lead‐Free ZnSnO₃ Triangular‐Belts

A flexible and transparent lead-free triangular-belt ZnSnO3 nanogenerator is demonstrated. When a mechanical deformation of ≈0.1% is applied to the triangular-belt ZnSnO3 nanogenerator, the output voltage and current reached 5.3 V and 0.13 μA, respectively, which indicated a maximum output power density of ≈11 μW·cm−3. This is the highest output power that has been demonstrated by lead-free ZnSnO3 triangular-belts. Detailed facts of importance to specialist readers are published as "Supporting Information".
