Capabilities of HASEL actuators | Artimus Robotics Information

Updated: Aug 17, 2023

This video discusses the core functionality, capabilities, and customizability of HASEL actuation technology, also known as HASEL artificial muscles. The unique capabilities of HASEL actuators include:

  • Diverse motion - Beyond contracting and expanding motions, HASEL actuators can also produce bending, twisting, and other highly complex motions.

  • Physical performance - The physical capabilities of a HASEL actuator depend on the specific geometry and design of the actuator. Typically, HASEL actuators are on the order of 1 to 10s of cm which results in maximum forces of 10-100s N, strains up to 100%, and frequencies from DC to 100s of Hz. All of these parameters can be optimized so please reach out to our design team to learn more.

  • Unique environments - As HASEL actuators do not contain any air, they are pressure agnostic, making them well suited for unique environments (high altitude or space, and deep sea). Additionally, the materials can be optimized to work in a wide range of temperatures, with typical ambient temperatures being the most common operating range.

  • Intelligence - HASEL actuators use capacitive sensing techniques to determine the position or force of the actuator in real time. This self-sensing enables HASEL actuators to be smart, providing highly valuable feedback on the actuator performance and operation.

To learn how your specific use case could make use of these capabilities of HASEL actuators, please reach out to us at to set up an introductory call.

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
