An increasing concern is on innovative methods of generating power that are sustainable and not concentrated. Powering small electronics in public areas with piezoelectric energy harvesting on a pair of human feet is one of such emerging and eco-friendly methods of generating electricity. The current paper refers to a study conducted that simulated the use of piezoelectric sensors to scavenge the power of footsteps. It realizes step 50 random steps in 60 s where each step emits a pulse of voltage. We make use of electrical design on a resistor-capacitor (RC) circuit in order to store the energy we gather. The simulation calculates the voltage, current, power and energy at variable times. The most significant measurements include power spectral density, accumulated energy storage, energy harvesting efficiency. The outcomes indicate that piezoelectric sensors are effective to harness mechanical energy and convert the energy into electrical power. Such simulation will help us more on how to utilize these types of systems in real life public infrastructures.
