Large‐Area 2D Metasurface‐Based Triboelectric E‐Skin Arrays: Contact & Proximity Tactile Mapping with Broadband Acoustic Readouts

open access: yesAdvanced Materials, EarlyView.
Metasurface‐engineered NC‐TENG arrays integrate tactile pressure mapping, non‐contact gesture sensing, and acoustic signal readouts in one ultrathin module, and outperforms pristine PDMS in terms of electrical output and real‐time spatial mapping for next‐gen wearables.

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

open access: yesAdvanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

The diagnostic value of three-dimensional echocardiography and speckle tracking echocardiography in patients after myocardial infarction with right ventricle involvement (clinical case)

open access: yesZaporožskij Medicinskij Žurnal, 2018
The inferior myocardial infarctions (MI) of left ventricle (LV) are often complicated with right ventricle (RV) involvement. The traditional echocardiographic parameters lack diagnostic accuracy in assessment of RV function.
