Wireless body sensor nodes (WBSNs) are miniaturized devices that are able to acquire, process and transmit bio-signals (such as electrocardiograms, respiration or human-body kinetics). WBSNs face ...

Here in, a tunable nano refractive index sensor structure consisting of a metal-insulator-metal (MIM) waveguide with a metal stub coupled with a protractor type half ring cavity (PTHRC) is designed ...
