Adaptive barrier systems that dynamically respond to environmental stimuli through changes in their physical or chemical properties.

Responsive Membranes

Responsive membranes are sophisticated barrier systems that can detect and react to changes in their environment through controlled modifications of their structure, permeability, or surface properties. These adaptive interfaces represent a convergence of materials science and biomimicry, often drawing inspiration from natural cellular membranes.
