Temperature‐Resilient Reconfigurable Physical Unclonable Function Driven by Pulse Modulation Using CMOS‐Integrated Spintronic Chips (Adv. Sci. 37/2026)

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Temperature‐Resilient Reconfigurable PUF A CMOS‐integrated SOT‐MRAM chip enables a temperature‐resilient reconfigurable physical unclonable function through dual‐pulse modulation. By widening the operating window and harnessing intrinsic variability, it ensures secure and dynamic key generation under extreme conditions.

Non‐Uniform Programmable Photonic Waveguide Meshes

Laser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.
Integrating defect cells into uniform hexagonal waveguide meshes overcomes the fundamental spectral and temporal limitations of programmable photonics. By leveraging the Vernier effect through non‐uniform coupled cavities, this architecture achieves a tenfold increase in free spectral range and ultra‐fast sampling times, paving the way for next ...

Swelling‐Induced Stress‐Assisted Transfer of Nanodiamond Arrays With a PVA Carrier Tape for Conformal Bio‐Integrated Sensing and Labelling

Advanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
This work introduces a swelling‐induced, stress‐assisted water‐soluble PVA tape strategy to transfer‐print nanodiamond quantum‐sensor arrays onto soft, curved biological interfaces. The room‐temperature, water‐triggered process achieves >98% fidelity and residue‐free integration, enabling conformal quantum sensing on contact lenses, neural probes, and ...

Physical Unclonable Function [PDF]

, 2019
A Physical Unclonable Function (PUF) is hardware that acts as a one-way function, whose each different instance provides unique outputs for the same distinct input. Although recent research has demonstrated the merits of PUFs as security primitives for resource-constrained computer systems, better implementations of them need to be identified ...

Silicon photonic physical unclonable function

Optics Express, 2017
Physical unclonable functions (PUFs) serve as a hardware source of private information that cannot be duplicated and have applications in hardware integrity and information security. Here we demonstrate a photonic PUF based on ultrafast nonlinear optical interactions in a chaotic silicon micro-cavity.
