Flexible multichannel muscle impedance sensors for collaborative human-machine interfaces.
Science advances
Jun 27, 2025
The demand for advanced human-machine interfaces (HMIs) highlights the need for accurate measurement of muscle contraction states. Traditional methods, such as electromyography, cannot measure passive muscle contraction states, while optical and ultr...
Tailoring neuromuscular dynamics: A modeling framework for realistic sEMG simulation.
PloS one
Jun 12, 2025
This study introduces an advanced computational model for simulating surface electromyography (sEMG) signals during muscle contractions. The model integrates five elements that simulate the chain of processes from motor intention to voltage variation...
Self-organising bio-inspired reflex circuits for robust motor coordination in artificial musculoskeletal systems.
Bioinspiration & biomimetics
Jun 6, 2025
Artificial musculoskeletal systems mimic mammalian biomechanics using antagonistic muscles and rigid skeletons. They offer benefits such as adjustable stiffness, back-drivability, and muscle failure tolerance but are difficult to model and control du...
Biohybrid robot contracts like the human iris.

Patterning planar muscle layers can create biohybrid robots capable of unique and controllable muscle activity.
Biohybrid hand actuated by multiple human muscle tissues.
Science robotics
Feb 12, 2025
Cultured muscle tissue serves as a power source in biohybrid robots that demonstrate diverse motions. However, current designs typically only drive simple substrates on a small scale, limiting flexibility and controllability. To address this, we prop...
Resilience of hierarchical actuators highlighted by a myosin-to-muscle mock-up.
Bioinspiration & biomimetics
Feb 10, 2025
Skeletal muscle is the main actuator of various families of vertebrates (mammals, fish, reptiles). It displays remarkable robustness to micro-damage, that supposedly originates both from its redundant hierarchical structure and its nervous command. A...
Monolithic electrostatic actuators with independent stiffness modulation.
Nature communications
Jan 30, 2025
Robotic artificial muscles, inspired by the adaptability of biological muscles, outperform rigid robots in dynamic environments due to their flexibility. However, the intrinsic compliance of the soft actuators restricts force transmission capacity an...
A neuromechanics solution for adjustable robot compliance and accuracy.
Science robotics
Jan 22, 2025
Robots have to adjust their motor behavior to changing environments and variable task requirements to successfully operate in the real world and physically interact with humans. Thus, robotics strives to enable a broad spectrum of adjustable motor be...
Genetic algorithm-based optimal design for fluidic artificial muscle (FAM) bundles.
Bioinspiration & biomimetics
Dec 3, 2024
In this paper, we present a design optimization framework for a fluidic artificial muscle (FAM) bundle subject to geometric constraints. The architecture of natural skeletal muscles allows for compact actuation packaging by distributing a substantial...
Impedance for Assistance: Upper-Limb Assistive Soft Robotic Suit Using Linked-Layer Jamming Mechanisms.
Soft robotics
Nov 29, 2024
Wearable robots, especially those composed of soft materials, are increasingly attracting interest due to their comfort, ease of donning and doffing, and their ability to provide assistance across various applications. In wearable robotics, striking ...
