1. A heart stimulation system, comprising:
a controller, comprising:
at least one wireless power signal generator configured to generate at least one power transfer signal;
at least one wireless power transmitter configured to transmit the at least one power transfer signal;
a memory containing a stimulation control application; and
a processor configured to execute the stimulation control application to generate and transmit the at least one power transfer signal; and
one or more wirelessly powered, leadless pacemakers (WPLPs), each WPLP comprising:
a wireless power receiver configured to receive a power transfer signal from the at least one power transfer signal;
an energy harvesting circuitry configured to store energy from the received power transfer signal; and
a stimulation circuitry configured to deliver the stored energy via a stimulation electrode which is triggered by a zero-amplitude gap in the power transfer signal.
