BIONIK – Bidirectional Interface between Neuroorthoses and Users for Interactive Control
As of April 1, 2026, the BIONIK project officially launches as part of the BMFTR-funded START-Interaktiv program. With a total funding volume of 0.96 million Euros over three years, BIONIK brings together interdisciplinary expertise in a joint effort with the Institute of Factory Automation and Production Systems (FAPS) at Friedrich-Alexander-Universität Erlangen-Nürnberg.
BIONIK builds directly on the scientific and technological foundations established in the Medical Valley Award project GraspAgain and the ERC Starting Grant project GRASPAGAIN. These initiatives have paved the way for a new generation of neurotechnological systems that more closely integrate human users into the control loop.
Towards True Human–Technology Interaction
Current active neuroorthoses support motor function but largely operate in a unidirectional manner, i.e., translating user intent into movement without providing meaningful sensory feedback. This limitation often results in reduced movement quality, increased cognitive load, and limited usability in everyday life.
BIONIK addresses this gap by developing bidirectional neurotechnological interfaces that enable real-time interaction between the human nervous system and assistive devices. At the core of the project is the concept of sensorimotor feedback: targeted vibrotactile stimulation is used to modulate neural excitability and provide intuitive feedback on movement execution via the somatosensory system.
Adaptive, Intelligent, and User-Centered
To achieve seamless interaction, BIONIK integrates adaptive sensor systems, machine learning algorithms, and a shared autonomy framework. These components allow the system to dynamically adjust to individual user capabilities, accounting for variability in signal quality, fatigue, and residual motor function.
This approach enables continuous co-adaptation between user and technology, reducing cognitive burden while enhancing control precision and intuitiveness. The project aligns closely with the goals of the START-Interaktiv program, which emphasizes interactive technologies that foster cooperation between humans and technical systems.
Strong Partnership and Future Outlook
We are excited to continue our successful collaboration with the FAPS at FAU, combining expertise in neuroengineering and mechatronics systems. At the same time, BIONIK serves as a platform for exploring new, innovative solutions at the interface of humans and technology
The insights gained from BIONIK will contribute to the development of evidence-based neurotechnologies and next-generation rehabilitation strategies. Ultimately, the project aims to improve user autonomy and participation, while supporting sustainable healthcare solutions in the context of demographic change.
