How HASEL actuators work | Artimus Robotics Introduction to HASEL actuators

Updated: Aug 17, 2023

This video provides an introduction to Artimus Robotics’ HASEL actuation technology.

The primary components of HASEL actuators are:

  1. Thin polymer film

  2. Liquid dielectric

  3. Flexible conductor.

How the HASEL actuator works:

HASEL actuators are electrically controlled. A high voltage is applied to opposing electrodes positioned on either side of the HASEL actuator. This voltage induces an electric field across the liquid dielectric which introduces localized pumping of the liquid dielectric to drive shape change, which drives actuation or motion.

HASEL actuators can be designed for contracting (C-Series), expanding (E-Series), or other unique motions. The electric control of HASEL actuators provides high control of the actuators. If you are interested in learning more about HASEL actuators please reach out to us at

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
