Piezo electricity generation using piezoelectric disk(buzzer).

AI Thread Summary
Piezoelectric disks can effectively generate energy from pedestrian movement on footpaths, producing voltages between 10mV to 100mV per disk. To maximize energy output, using multiple disks in parallel is recommended, as this increases the total voltage generated. For circuit design, it's essential to research appropriate configurations that can efficiently harness and store the generated energy. The discussion encourages thorough research and development, emphasizing the importance of the project being student-led. Engaging with existing resources, such as previous forum threads, can provide valuable insights for the project.

Welcome to the PF.

This previous thread from here in the EE forum should be of help:

https://www.physicsforums.com/showthread.php?t=373327

Once you read that thread and do some other reading (assuming wikipedia comes back up tomorrow), let us know if you have specific questions. Remember, this is *your* school project, so you must do the bulk of the research and development work.
 
These discs can be used as guitar pickups and in that application generate voltages of about 10mV to 100mV... something for you to go on.
 
But the more no. Of disk produce more voltage that can be sufficiant power to store.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
