The scenario
A footstep-mounted piezoelectric transducer generates AC pulses that are rectified, smoothed, and stored in a supercapacitor before powering a switched load.
What is in this drawing
Read the decisions behind it.
01
Use Schottky diodes for low forward voltage drop in the bridge rectifier
02
Add large storage capacitance to capture intermittent footstep energy
03
Include a switch to isolate the load until enough energy is stored
Reusable for vibration or footstep energy-harvesting front ends that convert small AC signals into DC and buffer intermittent power.
