Damping Factors: Piezoelectric in Prosthetics

Damping Factors

The voltage source was used as the
proposed model. The main internal
parameters are as following:

- the output resistance RP
- the output capacitance CP

They are measured by a RCL meter (Fluke
PM6306).
The duration of the voltage response from
Figure 6.2 can be modelled as a secondorder
parallel RLC circuit. The resonance
equation can be express as a function of
complex frequency (S1 and S2), which was
used to determine the values of R, L and C.
