Demonstration of high-speed and precise actuation. Demonstration of high-speed and precise actuation. (A) A lever-arm setup was connected to two Peano-HASEL actuators in parallel for demonstrating fast and controllable actuation. (B) By applying a 13-kV voltage step, these actuators contracted fast enough to throw a ping-pong ball 24 cm into the air. Labeled times are measured from the start of contraction. (C) Incrementing voltage allowed controllable actuation of the arm, as shown in the progression of images with increasing voltage left to right. The yellow lines mark the position of the top of the ball for comparison. The ruler to the left of each picture shows 1-cm increments for scale. Nicholas Kellaris et al. Sci.
