Biomimetic skin interface decodes heterogeneous mechanical signals
—
in EngineeringWhat the study found The study found that a biomimetic metamaterial-based interface (BMMI), an engineered auxetic metamaterial substrate that reproduces the microrelief and mechanoreceptor architecture of natural skin, can selectively capture diverse mechanical signals from adjacent skin regions. The authors describe this heterogeneous set of skin mechanical signals as mechanodermal activity (MDA). Why the authors…

Chirality affects microcritical, not macrocritical, stability
—
in MechanicsAnalysis of periodic lattice metamaterials with rigid joints shows chirality affects microscale stability but not macroscale stability, enabling tailored critical mode activation.
