Self-powered, 'one-terminal' tactile sensor for wearables

fingertip-touchResearchers have designed a self-powered, 'one-terminal' tactile sensor that can distinguish various motions on a single electrode. They did this by using a thermoplastic polymer that can easily change the electrostatic signal in a selective area. The sensor array can perceive the position and the sequence of touches, shape of touching objects, and dynamic motions (sliding, rolling) of an object and can distinguish various motions on a single electrode.

Synthesis, properties and applications of 2D materials beyond graphene

2D-materialBy utilizing the natural atomic thickness, flexibility, and mechanical strength, flexible devices based on 2D materials are paving the new way to achieve novel flexible device applications that include flexible transistors, flexible optoelectronics, flexible sensors and flexible supercapacitors. Furthermore, mechanical robustness and their atomic thickness provide 2D materials with high transparency in the visible range and makes them suitable for flexible, transparent electronic devices that are subject to mechanical strain and cyclic stress.

Inserting mechanical drugs into living cells (w/video)

mechanical-drugThe mechanical properties of cells and their intracellular mechanical loads are as relevant for a cell's accurate functioning as the biochemical portion of the cell. This offers a novel perspective that addresses the study of cell mechanics and even the alteration of the mechanical equilibrium of the cells by using silicon chips as an intracellular intervention mechanism. These 'echanical drugs' open the possibility to determine and measure intracellular forces and internalization routes. They can also produce intracellular mechanical perturbations by altering the cell cycle and even, if they are designed accordingly, destroy the cells.

Perovskite photovoltaics for a greener Internet-of-Things

flexible-solar-cellOrganic and perovskite solar cells are very promising energy harvester for indoor Internet-of-Things (IoT) applications as the requirements that solar cells should satisfy to power IoT devices are quite different to the ones usually deemed necessary for application in outdoor-placed solar panels. The size of the single solar cell used in IoT applications is much smaller, and in combination with the lower power input available in low-light indoor settings as well as the emission spectra of light sources other than the sun, renders the need for high conversion efficiency paramount.

Nanotechnology-enabled low-cost, point-of-care, self-test of sodium in the comfort of your home

nanoparticlesResearchers have developed a point-of-care, portable, rapid, and cost-effective test for clinical diagnosis of sodium, which uses a paper printed colorimetric sensor that is based on Curcumin-functionalized copper (CuC) nanoparticles. They demonstrate that the proposed CuC paper strip can be used for detecting Na+ concentration within the whole physiological range in both blood serum and urine. Sodium is a vitally important electrolyte present in all body fluids and it plays a crucial role in maintaining normal body function, including nerve and muscle function.

Nanotechnology in the Olympic Winter Games

skiingModern sports equipment often appears to be a showcase for new material technologies and nowhere has this been more true than in global sport competitions. Some of the high-tech materials used by athletes in competitive winter sports are using nanomaterials. But, as the 2022 Beijing Winter Olympics has shown, other areas have benefited from nanotechnologies and nanoscience as well: ice skating, wearable monitoring devices, and even nanomaterial-based Braille printing of Olympic service manuals and spectator guides for vision impaired readers.

Interface engineering enables tunable topological transitions in biaxial crystals

field-distributionsPolaritons in biaxial crystals offer a promising route to manipulate nanoscale light-matter interactions. The dynamic modulation of their dispersion is of great significance for future integrated nano-optics but remains challenging. Researchers theoretically demonstrate and experimentally verify such tailored polaritons at the interface of heterostructures. The interface engineering may shed new light on programmable polaritonics, energy transfer, and neuromorphic photonics

The future of contact lenses - lab-on-a-lens, augmented reality, and head-up displays

smart-contact-lensOngoing smart contact lens research ranges from biosignal detection (intraocular pressure, glucose, cortisol) to therapeutic tools (aniridia, chronic ocular inflammation) and advanced features such as aumented reality displays and personalized designs using 3D-printing technology. Some of these technologies are already finding their way from the lab into commercial applications. The development of next-generation, smart contact lens technology is not just simply one field of bioelectronics but rather a complex, interdisciplinary effort that includes development of biocompatible materials; development of intuitive interfaces; and development of integration technologies capable of smart contact lens research.
