Haptic Feedback with HASEL Actuators

Updated: Jan 31

Haptic feedback is a common way for devices to communicate with users. The vibration setting of a cell phone or video game controller is the most familiar example of traditional touch-based haptic feedback, but haptics can include visual responses such as lights or visual-touch combinations, such as those found in aircraft training simulations.


The requirements for haptic actuators are increasing as applications demand more functionality. Automotive manufacturers are integrating non-visual communication systems in car seats, armrests, and steering wheels to improve Advanced Driver Assistance Systems (ADAS) such as blind-spot detection (haptic cue). Medical manikin patient simulators imitate breathing, pulse, and other normal body functions but also need an abrupt signal to the medical trainee for certain reactions. AR/VR needs both human-like touch and distinguished mechanical touch for a comprehensive experience.


HASEL actuators can advance the capabilities of haptic communication in these applications due to the wide bandwidth of these actuators. Not only can HASEL actuators provide vibration at high frequencies, but also they demonstrate truly organic, lifelike motion at lower frequencies. Additional benefits include silent operation and a soft-compliant structure. Further, the integration of HASEL’s intelligent self-sensing opens new capabilities and sensations in haptics that were not previously possible.


Benefits of HASEL actuators as haptic devices:

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.
