Symmetry Breaking Metamaterial Sleeve Actuators

Advanced Intelligent Systems, EarlyView.
Metamaterial sleeves are designed to impart to a soft inflatable structure, nonlinear characteristics within the pressure–volume domain. By tuning the unit cells of the metamaterial sleeve, symmetry breaking is achieved during the inflation–deflation cycle.

An Ultrathin and Lightweight Soft Inflatable Actuator for Natural Tactile Sensory Feedback

Advanced Intelligent Systems, EarlyView.
A lightweight, ultrathin soft actuator mimics natural touch by delivering strong, multimodal haptic feedback through pressure and vibration. Tested on both able‐bodied individuals and amputees, it achieves high sensory precision in a compact form. Its simplicity, power, and adaptability hint at transformative applications in prosthetics, immersive ...

Ultralight Soft Wearable Haptic Interface with Shear‐Normal‐Vibration Feedback

Advanced Intelligent Systems, EarlyView.
This study proposes soft wearable haptic interface using pneumatic actuators and origami pumps. This interface can generate multiple sensations such as touching, slipping, and vibrating. To show performance and wearability of this interface, virtual reality is connected with the interface, and user tests are conducted.
