How can I construct a piezoelectric generator using cheap materials??
Hello! I am asking this because I need help in making my research project for my fourth year in high school. The concept of my research is to harvest energy from people stepping on something similar to stairs. after harvesting the energy, I plan on storing it in a pair of AA NiMH batteries for future storage, but I am still not sure on how I will go about this. As a high school student, I don't have any advance knowledge on making generators like you brilliant people do. Please help me. Thank you!
