Steady-state tissue voltage. Charge accumulation across the blocking capacitors and electrode capacitance can lead to time-dependent changes in the applied tissue voltage before a steady-state voltage (Vsteady-state) is achieved. Vstim is the pulse amplitude applied by the implantable pulse generator. The stimulus shown above had the following parameters: pulse amplitude = 1 V, pulse width = 450 μs, pulse frequency = 250 Hz, stimulation configuration = bipolar, impedance = 1 kΩ. A) The time-dependent tissue voltage (Vtissue). B) The time-dependent voltage across both blocking capacitors (Vblock) and both stimulation electrodes (Velec) for the bipolar stimulation.
