An electrowetting system with protection against dielectric breakdown is presented. It comprises an electrolyte and a Parylene-C film deposited on an aluminum electrode. The system demonstrates virtually instantaneous self-healing (within 100 ms) after dielectric breakdown under both DC and certain AC electrowetting conditions. DC current response during electrowetting on intentionally damaged Parylene-C is presented. Also presented is a characterization of DC offset voltages and duty cycle percentages required for electrolysis free AC electrowetting between 10 Hz and 4 kHz.
提出了一种具有介电击穿保护的电润湿系统。它包括电解质和沉积在铝电极上的 Parylene-C 薄膜。该系统在直流和某些交流电润湿条件下发生介电击穿后，几乎可以瞬时（在 100ms 内）自我修复。展示了在有意损坏的 Parylene-C 上电润湿期间的直流电流响应。还介绍了在 10Hz 至 4kHz 之间无电解自由交流电润湿所需的直流偏置电压和占空比百分比的特性。
