Claim 8:
9. A token comprising:
a power circuit that powers components of the token;
an energy storage device coupled to the power circuit;
one or more stationary piezoelectric crystals; and
a movable pendulum mass;
the token configured to:
generate electrical current from the movable pendulum mass moving to strike the one or more stationary piezoelectric crystals of the token;
charge the energy storage device with the generated electrical current;
select the energy storage device as an energy source for the token; and
energizing the power circuit with energy stored in the energy storage device,
wherein the energy storage device is a capacitor, wherein the capacitor is a multilayer capacitor that includes at least three conductive electrodes, wherein the multilayer capacitor includes a first set of planar conductive electrodes interleaved with a second set of planar conductive electrodes, the multilayer capacitor further includes a first non-overlapping region where the first set of planar conductive electrodes does not overlap with the second set of planar conductive electrodes, and a second non-overlapping region where the second set of planar conductive electrodes does not overlap with the first set of planar conductive electrodes.
