在二维平面上驱动液态金属液滴，以演示受控驱动和选择性热点冷却。连续的电润湿使液滴在3厘米×3厘米的井内沿规定的路径移动。在11V直流驱动电压下，驱动液滴的末端速度达到13.3 cm/S。增加沿井边的电极数量可以更精确地定位液态金属液滴。这项技术允许被驱动的液滴在设备内的局部热点执行快速冷却。在10V直流驱动电压下，液态金属液滴使热点温度降低约7°C。
A liquid-metal droplet is actuated in a two-dimensional plane to demonstrate controlled actuation and selective hotspot cooling. Continuous electrowetting actuates the droplet to move along a prescribed path within a 3 cm × 3 cm well. The terminal velocity of the actuated droplet is achieved at 13.3 cm/s with an actuation voltage of 11 V DC. Increasing the number of electrodes along the well edges results in more precise positioning of the liquid-metal droplet. This technique allows an actuated droplet to perform rapid cooling at localized hot spots within the device. For an actuation voltage of 10 V DC, the liquid-metal droplet decreases the temperature of a hot spot by approximately 7 °C.
