Autonomous Sensing Architected Materials (Adv. Funct. Mater. 11/2025)

Autonomous Sensing Materials In article number 2411975, Shanmugam Kumar, Mattia Utzeri, and Hülya Cebeci introduce a novel framework combining theory, experiments, and finite element modeling to develop multiscale, multiphysics models for additive manufacturing-enabled piezoresistive lattice composites. By incorporating stress-dependent electrical resistivity and accounting for material, geometric, and contact nonlinearities, the model accurately predicts architecture-dependent responses, validated through infrared thermography. A closed-form gauge factor expression optimizes piezoresistive performance, while an Ashby chart analysis reveals a scaling law, opening doors to smart orthopaedics, structural health monitoring, and more.
