The maximum power density of the optimized device reached 94.08 W m −2 at an external resistance of 300 MΩ, which is higher than most reported TENGs based on PVDF composite films. Excellent durability of TENG based on natural sepiolite modified PVDF film was also demonstrated with little variation in output voltage over 1000 cycles.

The following equation was used to calculate output power: (1) P = V 2 R eq where V denotes the voltage between the Al electrodes The equivalent resistance was determined when the resistors and measurement device were connected in series as follows: (2) R eq = R in + R R
