Cutaneous Electrohydraulic (CUTE) Wearable Devices for Pleasant Broad-Bandwidth Haptic Cues Robotic Materials Department at MPI-IS 2025-01-09 | Scientists at the Max Planck Institute for Intelligent Systems developed compact wearable devices that deliver rich, expressive, and pleasant tactile sensations, thus offering unprecedented control over the tactile sensations that can be transmitted to the user. The tactile sensations created by the device can communicate diverse sensations ranging from calming to exciting, such as stroking the skin, the feeling of a heartbeat, and engines turning on and off. Remarkably, users perceive almost all of the tactile cues they experience as pleasant and can identify diverse signals with near-perfect accuracy.Learn more about "Cutaneous Electrohydraulic (CUTE) Wearable Devices for Pleasant Broad-Bandwidth Haptic Cues" in Advanced Science: onlinelibrary.wiley.com/doi/full/10.1002/advs.202402461Music attribution:Music by Kyrylo Momot from Pixabay

Biodegradable electrohydraulic actuators for sustainable soft robots Robotic Materials Department at MPI-IS 2023-03-20 | Scientists in the Robotic Materials Department in the Max Planck Institute for Intelligent Systems, Department of Soft Matter Physics at the Johannes Kepler University, and Paul M. Rady Department of Mechanical Engineering at University of Colorado Boulder have collaborated to build the first fully biodegradable electrohydraulic artificial muscles - based on gelatin, oil, and bioplastics. The potential of this biodegradable technology is demonstrated by using these artificial muscles to animate a robotic gripper, which could be especially useful in single-use deployments such as for waste collection. At the end of life, these artificial muscles can be disposed of in municipal compost bins; under monitored conditions, they fully biodegrade within six months. Using biodegradable materials for building artificial muscles in this way is just one step towards paving a future for sustainable robotic technology.
