Bioinspired Hybrid of Electrolysis and Fluidic Reaction (HEFR) Soft Actuator, Mimicking Natural Muscle Filament Motion With Electricity Generation Capability

Applied Bionics and Biomechanics, Volume 2026, Issue 1, 2026.
This study employs the hybrid of electrolysis and fluidic reaction (HEFR) technique to investigate an experimental soft actuator model designed as an artificial myosin. Energy is generated through chemical reactions involving acetic acid (CH3COOH), bicarbonate (NaHCO3), and water (H2O), combined with chemical electrolysis, which powers the soft ...

Modeling and control of a morphing airfoil structure

, 2020
The aeroelastic modeling and robust control design for a morphing airfoil concept is presented. A finite dimensional linear time invariant aeroelastic model was developed for a multi-input, multi-output morphing airfoil structure. The shape of the airfoil (NACA airfoil series 2415) was controlled by actuators distributed along the top airfoil surface ...
