The brine network in common sea ice boosts its flexoelectric response by three orders of magnitude, matching high-quality piezoelectrics and pointing to cost-effective energy harvesters for cold environments.
Achieving room-temperature blackbody-sensitive photodetectors with an ultrabroadband response is challenging. Here, the authors report a bioinspired detector using the 2D flat-band quantum material Nb3I8 that enables sensitive detection from the shortwave to the very long-wave infrared.
Zeolitic imidazolate (ZIF-67), a Co-based metal organic framework, is a promising candidate for Escherichia coli detection, but its application is hampered by poor electrical conductivity. Here, the authors present a Co/Mn-based ZIF-67 that leverages the synergistic action of two transition metals to enhance sensor sensitivity, demonstrating its potential for on-site pathogen monitoring.
Skin-conformal electronics enable intuitive, real-time gesture recognition through seamless integration of conformal sensing and intelligent processing. Reliable and precise human–machine interactions gain thus transformative potential in health care, robotics, immersive applications and other dynamic environments.
Developing electronic textiles which balance conductivity and high-resolution patterning is challenging due to the charged character of cellulose-based fibers. Here the authors report a silver-carbon nanotube ink which can be inkjet-printed onto poly-L-lysine coated cotton fabric for electronic textiles.
A series of block polymers with chiral helical structures were synthesized, introducing the chiral induced spin selectivity (CISS) effect into gas-phase chiral enantiomer detection by organic polymers.
The brine network in common sea ice boosts its flexoelectric response by three orders of magnitude, matching high-quality piezoelectrics and pointing to cost-effective energy harvesters for cold environments.
Ion migration under an electric field in a preconditioning process leads to highly efficient and stable bromide perovskite single-crystal X-ray photon-counting detectors.
An ultrathin, ultrasoft and ultrastretchable magnetoelastic on-eyelid sensor is developed to track eye movements. Decoding the eye blinking signals collected from this sensor, a one-dimensional convolutional neural network combined with an unsupervised clustering model classifies the level of cognitive fatigue with an accuracy of 96.4%.
