Abstract: A fully polymer-based flexible arc-shaped three-dimensional (3D) fiber Bragg grating (FBG) array bionic tactile sensor is presented, in which both the FBG array and the encapsulation layer ...

Abstract: In this letter, a general design criterion is proposed for optimizing non-uniform three-dimensional (3D) arrays to enhance near-field capacity in extremely large-scale MIMO (XL-MIMO) ...

The COVID-19 pandemic highlighted an urgent need for efficient, durable, and widely accessible vaccines. This prompted several important innovations in vaccine technology, and researchers continue to ...
