摘要：
A method includes: transmitting a first set of radio-frequency (RF) pulses to an implantable wireless stimulator device such that electric currents are created from the first set of RF pulses and flown through a calibrated internal load on the implantable wireless stimulator device； in response to the electric currents flown through a calibrated internal load, recording a first set of RF reflection measurements； transmitting a second set of RF pulses to the implantable wireless stimulator device such that stimulation currents are created from the second set of RF pulses and flown through an electrode of the implantable wireless stimulator device to tissue surrounding the electrode； in response to the stimulation currents flown through the electrode to the surrounding tissue, recording a second set of RF reflection measurements； and characterizing an electrode-tissue impedance by comparing the second set and the first set of RF reflections measurements.
