How to work out mechanical energy used to stroke a key on a keyboard
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?- knatedogg86

How to work out mechanical energy used to stroke a key on a keyboard
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...- knatedogg86

How to work out mechanical energy used to stroke a key on a keyboard
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...- knatedogg86
