A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.

An Electrically Conducting Water‐based Reversible Adhesive
A water‐based reversible glue is demonstrated. The glue has electrical properties similar to other conducting adhesives but can detach after an alkaline wash. Metal fillers are added to an aqueous mixture of polymer nanoparticles synthesized by emulsion polymerization. The nanoparticles are stabilized by poly(acrylic acid) chains bonded to them. The pH‐

RRAM Variability Harvesting for CIM‐Integrated TRNG
This work demonstrates a compute‐in‐memory‐compatible true random number generator that harvests intrinsic cycle‐to‐cycle variability from a 1T1R RRAM array. Parallel entropy extraction enables high‐throughput bit generation without dedicated circuits. This approach achieves NIST‐compliant randomness and low per‐bit energy, offering a scalable hardware
