Revolutionary exoskeletons: Medicine is relieved through innovative technology!
Chemnitz University of Technology is developing innovative exoskeletons to relieve the burden on surgeons. The aim is to improve ergonomics in the operating room.
Revolutionary exoskeletons: Medicine is relieved through innovative technology!
On April 23, 2025, the Professorship of Adaptronics and Functional Lightweight Design TU Chemnitz significant advances in the development of biomechatronic systems were announced. The aim of these systems is to noticeably relieve the strain on medical staff during surgical procedures. Long operations are not only exhausting, they also put strain on the surgeon's muscles and joints and thus increase the risk of wear and tear.
As part of the project “BiSOP – Biomechatronic systems to increase ergonomics in the operating room” the Sächsische Aufbaubank is providing funding until July 2027. The main focus is on the development of a hand exoskeleton that should enable precise movement control and effective force absorption. The kinematics of this system are based on natural hand movements, which supports intuitive use.
Innovative technologies for ergonomics
A central feature of the development is novel sensors that enable intuitive control of the exoskeletons. In addition, the research includes a module that allows energy-free holding of defined grip positions, which can reduce energy consumption and system size. Surgeons are actively involved in research by taking part in surveys and ergonomic studies and evaluating prototypes. Interested physicians have the opportunity to get in touch with the research team.
A crucial element for the functionality and acceptance of exoskeletons are the physical human-machine interfaces (pHMI). These interfaces have a significant influence on the wearing comfort and biomechanical effectiveness of the systems. Sensors measure the interaction forces between humans and exoskeletons to identify and avoid pressure points and uneven loads, describes exoskeletons.com.
Advances in measurement technology
However, current measurement methods have limitations because they often only record normal pressures and do not take lateral forces into account. Future solutions could be enabled by integrating near-infrared spectroscopy (NIRS) and kinetic measurements. NIRS is a non-invasive method that detects local changes in oxygen saturation and blood volume in tissue, opening up new analytical approaches. Kinetic measurements help to accurately record forces and pressure distributions at the contact points between humans and exoskeletons.
Better designs can be realized through detailed analysis of the stress and deformation of the tissue. Avoiding pressure points is crucial to increase comfort and safety for users. Overall, the effort is at a stage where this could all lead to user-centered and more effective exoskeleton systems, as well exoskeletons.com summarizes.
