Building on the insights gained from the strain and tapping tests, the bending and force sweep experiments were conducted to evaluate the stability and efficiency of PLLA films under more dynamic and varying mechanical conditions. These experiments, illustrated in Figure , provide a deeper understanding of the films' piezoelectric response to dynamic forces. The results, presented in Figure , reveal that voltage and current outputs increase with applied force, ranging from 0.1 N to 0.5 N. For unprocessed films, the voltage output peaked at approximately 0.23 V at 0.5 N, with a corresponding increase in current, reaching a current output of 0.12 nA. Films strained to 50% showed moderate improvements, reaching 0.32 V at 0.5 N and higher current outputs at approximately 3.23 nA. At 75% strain, the output improved further, with a peak-to-peak voltage of 0.4 V and consistently higher current values across all force levels peaking at 31.1 nA. Films strained to 100% exhibited the best performance, achieving a peak-to-peak voltage of 0.53 V and maintaining higher outputs even at lower forces. However, A similar current output was observed in the 100% strained film to 75%, resulting in a current output of approximately 31.2 nA. The bending and force sweep tests complement the strain and tapping data, demonstrating PLLA's versatility and reliability under dynamic mechanical conditions, making it suitable for biomechanical sensors and wearable devices.
