TL;DR: A soft, foldable collection of electrodes in open, fractal mesh geometries that can mount directly and chronically on the complex surface topology of the auricle and the mastoid to provide high-fidelity and long-term capture of electroencephalograms in ways that avoid any significant thermal, electrical, or mechanical loading of the skin.

Distinct Floquet topological classifications from color-decorated frequency lattices with space-time symmetries
TL;DR: In this paper , the anomalous topological zero modes that arise from the coexistence of a dynamical space-time symmetry and antisymmetry were investigated in a static Floquet Hamiltonian with unitary loops and stroboscopic evolutions.
