3D Mesoporous Electrodes Integrated with Soft Surgical Robotics for Putative Minimally Invasive Intraoperative Tumor Detection and Ablation Monitoring.

Flexible endoscopes equipped with multimodal sensors offer an innovative minimally invasive approach to perioperative diagnosis and intraoperative ablation monitoring, addressing the limitations of conventional mechanical- and optical-based techniques. Over the years, various miniaturized sensors have been developed, providing essential insights through minimally invasive surgeries (MIS). Among them, tactile sensors hold significant potential to revolutionize the diagnosis of tissue malignancy, serving to detect differences in the mechanical properties between healthy and cancerous tissues.

Enhanced thermal stability by short-range ordered ferroelectricity in KNaNbO-based piezoelectric oxides.

Industrial application of lead-free piezoelectric ceramics is prevented by intrinsic thermal instability. Herein, we propose a method to achieve outstanding thermal stability of converse piezoelectric constant () in lead-free potassium sodium niobate (KNN)-based ceramics by inducing a synergistic interaction between the grain size and polar configuration. Based on computational methods using phase-field simulations and first-principles calculations, the relationship between the grain size and polar configuration is demonstrated, and the possibility of achieving improved thermal stability in fine grains is suggested.

Magnetically Driven Powerless Lighting Device with Kirigami Structured Magneto-Mechanoluminescence Composite.

The energy crisis and global shift toward sustainability drive the need for sustainable technologies that utilize often-wasted forms of energy. A multipurpose lighting device with a simplistic design that does not need electricity sources or conversions can be one such futuristic device. This study investigates the novel concept of a powerless lighting device driven by stray magnetic fields induced by power infrastructure for obstruction warning light systems.
