Thank you Nsaspook :)

Hi all, I am wondering if there is a need for impedance matching to charge a battery from the source? Thank you

Thank you Tech99 I will consider your point (Y)

Hello Berkeman, I have attached the pic of piezoelectric generator, whereas EM generator is a simple generator with a coil of 500 turns made up of enamelled copper wire of 0.15 gauge and grade N35 Neodymium magnets. Both the transducers are assembled in an Aluminium casing which when pressed...

Hello everyone, I have two generators, piezoelectric and electromagnetic generator. Piezoelectrics are producing maximum voltage across 3 Mohm resistor where as EM generator is producing maximum voltage at 68 ohm. What would be the ideal load for to get the maximum output from both when...
