Article Synopsis
- The text discusses using special current pulse waveforms to enhance the charge-injection capacity of activated iridium oxide microelectrodes for neural stimulation.
- These waveforms are biphasic and asymmetric, meaning one phase lasts longer and has lower current compared to the other, which helps minimize electrode polarization.
- In tests, the technique achieved a maximum charge-injection capacity of 3.3 mC/cm² with cathodal-first pulses and 9.6 mC/cm² with anodal-first pulses, using specific bias voltages and pulse width asymmetries.
