yea, that's what i was afraid of...so in conclusion, at the moment using piezo-electric materials isn't an effiecent enough way to harvest electrical power?
Piezoelectric Project
I am working on a project that will use piezoelectric ribbons printed on rubber underneath a laptop keyboard to charge its battery. The conversion rate of the ribbons from mechanical energy to electric energy is 80%.
If I know the mechanical energy applied to the...
Sorry to bother you again but i can't get my head around this project.
If i know the mechanical energy applied to the ribbons will be say 1E-3 Joules and my laptop on average uses say about 80w and the specific piezoelectric ribbons are capible of converting 80% of mechanically energy into...
I am working on a project to use piezoelectric ribbons printed on rubber underneath a laptop keyboard to charge its battery. I have the conversion rate of the ribbons from mechanical energy to electric energy.
I need to work out how much mechanical energy is used (and what is the formula) to...
