EE Times “tears down” the Joule-Thief

The last time I really got my hands dirty playing with a piezoelectric transducer was for a small control system I designed back in college. That was a generic device that was more or less plug-and-go, so I can’t recall much about it. However, given the recent uptick in interest in energy-harvesting technology as a possible solution to powering remote and embedded devices, I figured it was time to take a closer look at piezoelectric (PE) transducers and their related electronics to see how far they’d come. So, I got hold of the Joule-Thief demonstration kit from AdaptivEnergy, performed an exam, and was blown away.
