Abstract
This study presents a flexible LSPR sensor based on gold nanoislands on a flexible glass substrate.Upon mechanical bending, the sensor exhibited a two-fold increase in refractive index sensitivity (from 96 to 205 nm/RIU), while maintaining stable extinction spectra. The enhancement may attributed to reduced interparticle spacing and increased near-field coupling. This bending-induced effect provides a simple yet effective strategy for sensitivity tuning in wearable plasmonic sensors.
