Abstract

A flexible bismuth (Bi)-based smartsensor capable of simultaneously detecting Cd²⁺, Tl⁺, and Pb²⁺ is proposed for the first time. Fabricated via a template-assisted electrodeposition method, this novel sensor demonstrates excellent selectivity in distinguishing these heavy metal ions (HMIs). The developed platform holds broad application prospects for on-site HMI monitoring.
