Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

Advanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB
