“…This discovery is a significant advance in the field, and its implications go far beyond molecular and cell biology. For example, the confined tension distribution in the cell membrane is consistent with a recent report in the field of nano-bioelectronics, 128,129 which shows that U-shaped nanowire-based intracellular penetration is dependent on the tip curvature (Fig. 6B).…”

“…b) and 1(c) show the ST-FMR signals measured for the Ni 81 Fe 19 /CuO x bilayers with Q = 3.0% and 5.5%, respectively. The measured ST-FMR signals V mix can be expressed as the sum of symmetric and antisymmetric Lorentzian functions[33,34]:V mix = V s L sym (H ext ) + V a L asy (H ext ), where L sym (H ext ) = W 2 /[(µ 0 H ext − µ 0 H FMR ) 2 + W 2 ] and L asy (H ext ) = W (µ 0 H ext − µ 0 H FMR )/[(µ 0 H ext − µ 0 H FMR ) 2 + W 2 ].Here, W and µ 0 H FMR are the linewidth and the FMR field, respectively.Figure 2(a)shows the symmetric and antisymmetric components of the measured ST-FMR signals, extracted by fitting the exper-…”

We report the observation of the intrinsic dampinglike spin-orbit torque (SOT) arising from the Berry curvature in metallic-magnet/CuO_{x} heterostructures. We show that a robust dampinglike SOT, an order of magnitude larger than a fieldlike SOT, is generated in the heterostructure despite the absence of the bulk spin-orbit effect in the CuO_{x} layer. Furthermore, by tuning the interfacial oxidation level, we demonstrate that the fieldlike SOT changes drastically and even switches its sign, which originates from oxygen-modulated spin-dependent disorder. These results provide important information for a fundamental understanding of the physics of the SOTs.

“…Size modulation such as decreasing diameter and material thicknesses is commonly used to achieve conformability enabled by strain engineering. [125,129] In neuron activity recording, electrodes with the neuron-like dimensions shows reduced mechanical stiffness by 5-20 times compared to reported flexible probes, which allows the probing and modulation of electrical and chemical signals at subcellular scale ( Figure 5b). [130,131] Decreasing thickness is widely used as bending strains are in reverse proportional to thickness.…”

Living things rely on various physical, chemical, and biological interfaces, e.g., somatosensation, olfactory/gustatory perception, and nervous system response. They help organisms to perceive the world, adapt to their surroundings, and maintain internal and external balance. Interfacial information exchanges are complicated but efficient, delicate but precise, and multimodal but unisonous, which has driven researchers to study the science of such interfaces and develop techniques with potential applications in health monitoring, smart robotics, future wearable devices, and cyber physical/human systems. To understand better the issues in these interfaces, a cyber–physiochemical interface (CPI) that is capable of extracting biophysical and biochemical signals, and closely relating them to electronic, communication, and computing technology, to provide the core for aforementioned applications, is proposed. The scientific and technical progress in CPI is summarized, and the challenges to and strategies for building stable interfaces, including materials, sensor development, system integration, and data processing techniques are discussed. It is hoped that this will result in an unprecedented multi‐disciplinary network of scientific collaboration in CPI to explore much uncharted territory for progress, providing technical inspiration—to the development of the next‐generation personal healthcare technology, smart sports‐technology, adaptive prosthetics and augmentation of human capability, etc.
