Multichannel Control of HASEL Actuators

A key benefit of HASEL actuators from Artimus Robotics is that they are highly controllable. This can be in the form of extremely variable motion in the actuators themselves, or in sophisticated synchronization, patterning, or sequencing groups of actuators with entirely independent control.

The following video demonstrates the features of multichannel control from Artimus Robotics. In this video, one active surface has eight individual expanding HASEL actuators. With multichannel control, these eight actuators can operate as eight individual pixels, each with their own unique motions independent of the other pixels. They can also be perfectly synchronized to actuate together, or divided into groups with programmable patterns. The actuators can have variable speeds (synchronized or independent) and can demonstrate sequential behaviors. In the second half of the video, the active surface shows some actuators operating with low frequencies and other actuators operating with high frequencies, all driven by the same controller.

Industries that can benefit from multichannel control are: human-machine interfaces (massage devices, haptic feedback devices, compression devices), industrial automation (conveyor systems, pump/valve systems, gripper end effectors), and automotive (smart surfaces, button-on-demand, ADAS).

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
