Speed Comparison: HASEL actuator vs. pneumatic actuator

Updated: May 7, 2022

HASEL actuators from Artimus Robotics are often compared to pneumatic actuators. Two characteristics are immediately noticed in these comparisons. First, HASEL actuators operate much more quietly than pneumatic actuators since HASEL actuators emit no noise during operation. Second, HASEL actuators operate much faster than pneumatic actuators.

At high frequencies, pneumatic actuators can’t move the fluid quickly enough to fully actuate or to actuate at the full speed. HASEL actuators are electrically driven and not dependent on the movement of a fluid, so they actuate at the speed of the electrical signal. This can be as fast as 5 ms in some applications.

The following video demonstrates the HASEL actuator speed compared to a pneumatic actuator across a range of frequencies. Both actuators are comparable at low frequencies, but as the frequencies increase, the pneumatic actuator can’t keep up. Please contact Artimus Robotics at to learn more.

About Artimus Robotics

Artimus Robotics designs and manufactures soft electric actuators. The technology was inspired by nature (muscles) and spun out of the University of Colorado. HASEL (Hydraulically Amplified Self-healing ELectrostatic) actuator technology operates when electrostatic forces are applied to a flexible polymer pouch and dielectric liquid to drive shape change in a soft structure. These principles can be applied to achieve a contracting motion, expanding motion, or other complex deformations. For more information, please visit Artimus Robotics or contact
