This research analytically investigates the effect of resistive load on transient performance a -mode piezoelectric vibration energy harvester. Through normalized voltage and power analyses under varying loads excitation frequencies, it is observed that peaks consistently at resonance frequency, with its magnitude increasing as resistance decreases. The power, however, exhibits maximum an optimal aligns system’s internal impedance, underscoring significance impedance matching for efficient harvesting. Transient dynamics reveal faster dissipation higher fluctuations lower resistances, while resistances yield smoother but less transfer. These findings provide crucial insights into interplay between resistance, dynamics, optimization, paving way improved design application harvesters in real-world systems.
