Modeling and validation of magnetic tunnel junction device
Journal of Measurement Science and Instrumentation, 2017 We have presented here a simple model of magnetic tunnel junction（MTJ）device and the proposed MTJ model is utilized for validation purpose and also to study its tunnel magneto-resistance（TMR）effect by both simulation and experimental method using an ...

Atomistic Model of Magnetic Tunnel Junction Spin-Torque Nano-Oscillators
IEEE AccessWe have developed a model of a CoFeB/MgO magnetic tunnel junction nano-pillar for application as a spin torque nano-oscillator (MTJ-STNO) using an atomistic model combined with a spin accumulation model.

Advanced Materials Technologies, EarlyView.Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...

Multimodal Haptic Perception Through Synergistic Nanocomposite Sensor Arrays
Advanced Materials Technologies, EarlyView.Multi‐modal fingertip haptics are advanced through a bioinspired &vertical‐via' electronic skin architecture. A confined PDMS/MWCNT/NiNP nanocomposite, sitting at the percolation threshold, enables tactile, thermal, and magnetic sensing. A unique via‐density gradient and dedicated &Un‐Touch' reference nodes provide robust spatial resolution and signal ...

Scientific ReportsWe present a comparative study of perpendicular magnetic tunnel junctions (p-MTJs) incorporating either a single CoFeB free layer or a double free layer structure consisting of two 1.2 nm CoFeB layers separated by a 0.3 nm Ta spacer.

Self‐Assembled Calcite Architectures for Programmable Information Storage
Advanced Materials Technologies, EarlyView.Programmable biomineralization enables the formation of 3D calcite architectures that encode information through spatially defined refractive‐index modulations. Data are written via laser‐directed mineralization, stored in stable voxelized mineral structures, and retrieved non‐destructively through optical diffraction, offering a pathway toward ultra ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

CD4+ Tregs Drive Post‐Ischemic Sprouting Angiogenesis via Endothelial YY1/MAML1 Reactivation
Advanced Science, EarlyView.ABSTRACT Microvascular complications of diabetes are chronic diseases of small vessels. We previously found that CD4+ regulatory T‐cells (Tregs) are markedly reduced in type 2 diabetes (T2D) after ischemic injury in both mice and humans, and that Treg deficiency in immunodeficient mice impairs vascular regeneration.
