Unprocessed films displayed a voltage peak-to-peak of 0.27 V at 30 Hz, with a significant drop to 0.05 V at 50 Hz and the measurements became more unstable at higher frequencies. Current outputs followed a similar trend, peaking at approximately 1,21 nA at 30 Hz and 40 Hz and decreasing, reaching almost 0 nA at 50 Hz. These results highlight the limitations of unprocessed PLLA in maintaining consistent performance under dynamic conditions.
