Hi everyone! I am currently working on project involving piezoelectricity and would really appreciate any and all feedback/corrections/advice. The question I’m trying to answer is, “How much energy is produced when piezoelectric elements are placed on top of the keys of a laptop and what percent of the energy required to charge a battery does this represent?” I’m going to go about answering this by collecting the following measurements:
Some of my questions are:
Thank you so much for getting this far, I really appreciate any help
- What is the average amount of energy generated per keystroke on the piezoelectric-equipped key?
- How much energy is stored per average keystroke on a piezoelectric-equipped key wired to a capacitor?
- How much energy is generated and stored when the same procedure is used but with multiple keys wired in a circuit?
- How does this amount of energy compare to the amount of energy required to charge a battery?
Some of my questions are:
- What units should I be using to measure “energy”?
- How can I ensure that each time an element is struck, it is with the exact same amount of force?
- How can I directly compare the number of keystrokes it takes to charge a capacitor to how many it would take to recharge a battery?
Thank you so much for getting this far, I really appreciate any help
