Abstract Flexible electronic skins (e‐skins) with high sensitivity and broad‐range pressure sensing are highly desired in artificial intelligence, human–machine interaction. Capacitive‐type e‐skins have a simple configuration, but the change dimensions of dielectric layer is often quite limited, although introducing surface microstructures might improve some extent. Moreover, such structures typically require costly microfabrication methods to fabricate. Here, low‐cost microstructured ionic...
Abstract High‐temperature dielectric materials for capacitive energy storage are in urgent demand modern power electronic and electrical systems. However, the drastically degraded capabilities owing to inevitable conduction loss severely limit utility of polymers at elevated temperatures. Herein, a new approach based on situ preparation oxides onto polyimide (PI) films high‐temperature laminated polymer dielectrics is described. As confirmed by computational simulations, charge injection...

Cryo-electron microscopy study finds that EC-based electrolyte can exfoliate the graphite surface and destabilize SEI. Useful additives including FEC, DTD, TPP, VC form a stable SEI to protect anode.
Artificial skins or flexible pressure sensors that mimic human cutaneous mechanoreceptors transduce tactile stimuli to quantitative electrical signals. Conventional trial-and-error designs for such devices follow a forward structure-to-property routine, which is usually time-consuming and determines one possible solution in run. Data-driven inverse design can precisely target desired functions while showing far higher productivity, however, it still absent because of the difficulties...
The authentication of olive oil and its adulteration with lower priced oils are still serious problems in the industry. In this study, a method based on intensity ratio Raman spectroscopy vibration bands, especially cis (═C—H) (C═C) bonds normalized by band at 1441 cm−1 (CH2), was established to authenticate genuine/fake oil. These ratios bands given form two-dimensional chart allow first discrimination between various grades seed then detection fraud line y = 0.7, which is observed under...
