Haptic Actuators with Wide Bandwidth

Updated: Mar 15, 2023

HASEL actuators from Artimus Robotics are one of the most advanced haptic actuator technologies (also called tactile actuators, tactile transducers, haptic vibration, vibrotactile, taptic engines, or haptic motors). The soft compliant structure of HASEL actuators makes them ideal for on-body or near-body applications (HASEL actuators are touchable) or physically transparent and unobtrusive when integrated into an on-body or near-body product. HASEL actuators don’t contain metals or magnets - unlike Eccentric Rotating Mass (ERM) actuators, voice coils, piezoelectrics, and other traditional haptic actuator technologies. Instead, they are made from light and flexible materials which makes them a great fit for mobile, portable, and wearable haptic applications. The electric control of HASEL actuators facilitates a wide bandwidth, meaning they work at both high frequencies and low frequencies, and these actuators perform exceptionally well in the low-to-middle range of frequencies (1 Hz to 100 Hz but HASEL actuators can operate below 1 Hz). These frequency ranges allow for a variety of haptic sensations, from low-frequency squeezes to high-frequency vibrations. Additional benefits of HASEL actuators for haptic actuator applications include silent operation, intelligent self-sensing, and the ability to customize shape, size, and performance (see this miniature “fingertip” actuator demonstration).

Applications that are actively exploring HASEL actuators for haptic actuator applications include:

  • AR/VR/Metaverse accessories

  • Automotive haptic signals

  • Enterprise training products

  • Gaming accessories

  • Wearables for medical and consumer uses

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
