Wearable Robotic Glove Restores Hand Function

Researchers from the Medical University of Vienna, working with collaborators from ETH Zurich, the Technical University of Munich, and the University of Belgrade, have developed a wearable neurorobotic system designed to restore hand function in people with severe neurological impairments. The system combines a lightweight robotic hand exoskeleton with functional electrical stimulation (FES), which activates weakened muscles through carefully timed electrical impulses. By synchronizing robotic assistance with the user's own muscle activity, the device enables more natural and coordinated grasping and finger movements than conventional rehabilitation approaches.

The researchers evaluated the system in individuals with spinal cord injuries and stroke-related hand paralysis, demonstrating significant improvements in performing everyday tasks such as grasping and manipulating objects. Unlike existing rehabilitation devices that often rely solely on robotics or electrical stimulation, the hybrid approach leverages the strengths of both technologies, promoting functional recovery while encouraging active patient participation. The team believes the wearable system could support both clinical rehabilitation and home-based therapy, offering a practical solution for improving independence and quality of life for people with impaired hand function.

OriRing VR Ring

Researchers at Sungkyunkwan University, in collaboration with EPFL, have developed a novel wearable haptic device called OriRing. This ring-shaped interface uses a 3-axis force sensor to provide users with realistic sensations of the weight and stiffness of virtual objects when interacting in VR. Unlike traditional haptic systems that rely on simple vibrations or bulky mechanisms, OriRing is ultra-lightweight (about 18 g) and capable of sensing multi-directional forces through micro-structured polymer surfaces, allowing precise tactile feedback directly at the fingertip.

Testing showed that users can not only perceive object properties like size and hardness but also adjust virtual object characteristics in real time using just finger movements. Because of its high force-to-weight performance and compact wearable form, OriRing offers advantages over glove-type devices and has potential applications beyond VR and gaming, such as rehabilitation, medical use, and remote robotic control. The research was published in Nature Electronics and marks a step forward in creating more immersive and physically grounded human-computer interaction technologies.

Smart Textiles Use Acoustic Waves

Researchers at ETH Zurich developed smart textiles that rely on acoustic waves passed through glass fibers. This makes the measurements more precise and the textiles lighter, more breathable, and easier to wash. The researchers have woven glass fibers into the fabric at regular intervals. At one end of each glass fiber is a small transmitter that emits sound waves. The other end of each of the glass fibers is connected to a receiver that measures whether the waves have changed.

Each transmitter works at a different frequency. This means it requires little computing power to determine which fiber the sound waves have changed on. Previous smart textiles often struggled with data overload and signal processing issues, since each sensor location had to be evaluated individually. When a glass fiber moves, the length of the acoustic waves passing through it changes, as they lose energy. In the case of a T-shirt, this can be caused by body movement or even breathing.
