    HELP! how can i increase a piezo electric current?

    Yes sir, we are trying to power up the LED. But the LED is too dim when we apply mechanical forces. We tried 4 transducers in parallel but the LED is still too dim. I searched about Darlington Circuit, is it advisable to use this circuit to increase our current with battery?

    HELP! how can i increase a piezo electric current?

    We have a small project about piezo electric. We used ceramic transducers and our problem is that the current is too small. Our LED's are dull and not a bright as the normal brightness of LED's. Please lend us some advice on how to increase our current. Does Darlington Circuit really helps...
