This study demonstrates that lipid membranes exhibit non-linear memory effects, where their capacitance changes in response to accumulated charge, linked to membrane shape and curvature alterations. The membranes show a hysteretic buckling response to oscillatory electric fields, suggesting bistable states that could be used for memory storage. A circuit model is introduced to capture these dynamic effects, offering insights into potential applications for energy storage and neuromorphic computing.

We demonstrated that electrical stimulation can modify the characteristics of the lipid membrane, indicating a novel mechanism for storing memory in the human brain.
