Scientists have engineered a biorobotic arm designed to mimic and counteract tremors experienced by patients with conditions like Parkinson’s disease. The device utilizes strands of artificial muscles that contract and relax to compensate for involuntary movements.

Researchers estimate that tremors affect approximately 80 million individuals worldwide, considerably impacting their ability to perform everyday tasks such as holding objects or writing. Soft exoskeletons offer a potential solution, but current prototypes require further refinement.
as part of the Bionic Intelligence Tübingen stuttgart (BITS) research collaboration, scientists from the Max Planck Institute for Intelligent Systems (MPI-IS), the University of Tübingen, and the University of Stuttgart have developed a biorobotic arm equipped with artificial muscles along the forearm.
The robotic arm replicates tremor movements,allowing researchers to test tremor suppression techniques. When activated, the electro-hydraulic actuators – the artificial muscles – contract and relax to counteract the shaking motion, effectively minimizing the tremor. A video demonstration is available here.
Robot Arm as a Testing Platform
The research team envisions the biorobotic arm serving two primary purposes. First, it provides a platform for researchers to evaluate new exoskeleton technologies. Biomechanical computer simulations allow developers to assess the effectiveness of their soft actuators without extensive clinical trials.
Second, the arm facilitates the growth of artificial muscles, specifically Hydraulically Amplified Self-healing Electrostatic (HASEL) actuators, by the Department of Robotics Materials at MPI-IS. The long-term goal is to integrate HASEL technology into portable exoskeletons, enabling tremor patients to perform daily activities with greater ease.
Potential for Wearable Technology
Alona Shagan Shomron,a Postdoc at the Department of Robotics Materials at MPI-IS and lead author of the study published in the journal *Device*,stated,”We see great potential to sew our artificial muscles one day in a piece of clothing that can be carried discreetly.” Shagan added, “We have shown that our artificial muscles based on the HASEL technology are fast and strong enough to suppress many different tremors, showing the great potential of a portable aid on a HASEL basis for people who live with this restriction.”
Daniel Freestl, a professor at the Hertie Institute for Clinical Brain Research at the University of Tübingen, noted the importance of the biomechanical model in testing the artificial muscles. “With the combination of mechanical patient and biomechanical model, we can measure whether the artificial muscles tested are good enough to suppress all, also very strong, tremor movements. If we woudl ever develop a portable device, we could adapt it individually to every tremor,” Freestl said.
Early-Phase Clinical testing
Syn Schmitt,Professor of Computational Biophysics and Biorobotics at the University of Stuttgart,emphasized the value of the “mechanical patient” in early-stage technology development. “The mechanical patient enables us to test the potential of new technologies at a very early stage of development without being necessary to need expensive and time-consuming clinical tests on real patients,” Schmitt said.
Christoph Keplinger, director of the Department of Robotics Materials at MPI-IS, highlighted the broader implications of the research. “the robotics show great potential for applications in healthcare. This triumphant project underlines the key role, which will play soft robot systems based on flexible and deformable materials,” Keplinger said.

Bionic Arm: Using Artificial Muscles to Fight Tremors – Q&A
Published: April 10, 2025
What is this new bionic arm designed to do?
The bionic arm, engineered by scientists, is designed to mimic and counteract tremors, especially those experienced by individuals with conditions like Parkinson’s disease. It uses artificial muscles to respond to and suppress involuntary movements.
How does the bionic arm work?
The arm utilizes strands of artificial muscles, also known as electro-hydraulic actuators, that contract and relax to counteract the shaking motion of tremors. These actuators effectively minimize the tremor by moving in opposition to the involuntary movements.
What are artificial muscles, and how are they used in this device?
The research utilizes Hydraulically Amplified Self-healing Electrostatic (HASEL) actuators, which are a type of artificial muscle. These actuators are integrated within the bionic arm to provide the necessary movement to counteract tremors. They contract and expand to replicate the actions of natural muscles.
What is the potential impact of this technology?
This technology has the potential to significantly improve the lives of the approximately 80 million people worldwide who experience tremors. It can make everyday tasks, such as holding objects or writing, easier to perform.
What is the significance of the “mechanical patient”?
The “mechanical patient” is an essential element in early-stage technology development. It allows researchers to test new technologies without the need for expensive and time-consuming clinical trials on actual patients. it enables developers to assess the effectiveness of soft actuators through biomechanical computer simulations.
What role does the BITS research collaboration play in this project?
The Bionic Intelligence Tübingen Stuttgart (BITS) research collaboration, involving scientists from the Max Planck Institute for Intelligent Systems (MPI-IS), the University of Tübingen, and the University of Stuttgart, is a key contributor to the development of this bionic arm. This collaboration brings together expertise in robotics, biomechanics, and related fields to advance tremor suppression technologies.
What are the two primary purposes the research team envisions for the biorobotic arm?
The team envisions the arm serving two main purposes:
- Providing a platform for researchers to evaluate new exoskeleton technologies.
- Facilitating the development of artificial muscles,specifically HASEL actuators,with the long-term goal of integrating HASEL technology into portable exoskeletons.
what are the long-term goals for this technology?
The long-term goal is to integrate HASEL technology into portable exoskeletons. This would enable tremor patients to perform daily activities with greater ease.
What is the potential for wearable technology in this context?
Researchers envision that the artificial muscles could one day be integrated into clothing as a wearable aid. The HASEL technology is fast and strong enough to suppress many different tremors, which would allow portable devices for individuals living with tremors.
what is the importance of biomechanical models in testing the artificial muscles?
Biomechanical models and simulations allow developers to assess the effectiveness of new soft actuators without needing extensive clinical trials. Using a combination of a “mechanical patient” and a biomechanical model, researchers can measure weather the artificial muscles are effective enough to suppress all tremor movements, including very strong tremors. A portable device could be adapted individually to every tremor.
Where can I find a video demonstration of this technology?
A video demonstration is available here.
