Artimus 101: Benefits of HASEL actuators | Artimus Robotics Introduction to HASEL actuators

Updated: Jan 31

In this video, Artimus Robotics CEO and cofounder, Dr. Tim Morrissey, discusses the benefits of Artimus Robotics’ core technology, HASEL actuators. These benefits can be customized for different applications and use cases.



Potential benefits of HASEL actuators include:

  • Electric Control. HASEL actuators are powered by electrostatics, meaning no need for pneumatic tubing, valves, and compressors. They can even be battery-powered.

  • Fast Actuation Speeds. Due to the electric control, HASEL actuators are very fast, operating with turn-on times as low as 10ms (can be optimized even faster if needed) and operating frequencies into the 100s of Hz.

  • Cost-Effective Materials. HASEL actuators are made from three core materials, thin plastic film, commodity liquid dielectrics, and commodity conductive ink. These low-cost materials make HASEL very cost-effective at scale.

  • Compact. HASEL actuators can take many forms but often are best suited for centimeter-scale actuation.

  • Soft Compliant Structure. Due to the use of liquids and thin plastic films, HASEL actuators are incredibly compliant and deformable - one of the softest actuator technologies that exist.

  • Lightweight. HASEL actuators are very lightweight due to the use of thin polymer films and liquid dielectrics. No heavy motors or metal components here.

  • Intelligent Self-Sensing. Using the capacitive nature of HASEL actuators, a basic impedance signal can be used to monitor the physical state of the actuator in real-time.

  • High Bandwidth. HASEL actuators can operate at frequencies ranging from DC to 100s of Hz and be further optimized to go to even higher frequencies if needed.

  • Silent Operation. HASEL actuators have no spinning motor or pneumatic pumps, they are very quiet, noiseless, and completely silent.

  • Rapid Prototyping. Artimus Robotics has the unique ability to rapidly develop custom HASEL actuators of various sizes and shapes.

  • Direct Linear Analog Motion. HASEL actuators use electrostatic principles to convert electric energy to linear motion. No spinning motors and gears.

  • Long Product Life. HASEL actuators have demonstrated lifetimes as high as millions of cycles. Lifetime is highly dependent on use conditions, please reach out to inquire about lifetime in your application.

  • Portable. As HASEL actuators are electrically operated, a battery-powered power supply allows HASEL actuators to be highly portable.

  • Versatile Organic Motion. The combination of analog motion, electrically-driven, and compliant structures allow HASEL actuators to move in an extremely organic and lifelike manner.

  • Easily Customizable. HASEL actuators are modular and Artimus Robotics is ready to make a custom actuator for your exact need. Please reach out to us 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.
