Can you recommend a source for a decent Barium Titanate (or higher efficiency) piezoelectric transducer of varying performance parameters for voltage generation, with an eye toward its potential for energy generation and storage?
And, I'm also interested in a source for the LTC3588 ic, available in small quantities for conversion. Do you also happen to know if it's possible to put the output from these ic's in series, or parallel for stacking to increase V or A output?
