the only setting that was able to provide any output was
the Superseries, Parallel setting. From approximately
0.175 gee to 0.25 gee the Normal, Series setting was
best. For all amplitudes above 0.25 gee the Normal,
Parallel was the most efficient. It should be noted that
these curves will vary substantially depending on the
product that is used as well as the tip mass that is used
to tune the product. In conclusion what this
representative curve shows is that the piezo’s output
energy and voltage for certain settings will allow the
system to operate closer to the half open circuit voltage
causing more efficient operation. For low level vibration
the series setting is needed to get the piezo voltage output
to reach the minimum voltage to operate the EHE004.
