PIN FUNCTIONS
Each Volture contains two electrically isolated piezo
wafers, which may be used independently or bridged
for increased voltage (series configuration) or current
output (parallel configuration). Series connection will
double the open-circuit voltage compared to a single
wafer, and the effective capacitance will be 1/2 the
single-wafer capacitance listed in the “Electrical
Characteristic Table (Pg. 3)”. Parallel connection will
double the current compared to a single wafer, and the
effective capacitance will be double the single-wafer
value. For most applications, parallel connection is

recommended. Please refer to the connection diagram
above. Regardless of series or parallel connection, the
power generated by the Volture™ Energy Harvester will
be the same.
In typical energy harvesting usage, the raw output is an
AC waveform as the Volture deflects in both directions.
For sensing or dual-use applications where it is desired
to know the direction of deflection at any given time,
please refer to the relationship between deflection and
output polarity for each wafer diagram below.
