A high-performance, all-solid-state Na⁺ selective sensor printed with eco-friendly conductive ink.

ABSTRACT: In recent years, the integration of flexible printed electronics and electrochemical sensors has emerged as a new approach for developing wearable biochemical detecting devices. Among the materials utilized in flexible printed electronics, carbon-based conductive inks are considered to be crucial. In this study, we propose a cost-effective, highly conductive, and environmentally friendly ink formulation utilizing graphite and carbon black (CB) as conductive fillers, resulting in a very low sheet resistance of 15.99 Ω sq^-1 (conductivity of 2.5 × 10³ S m^-1) and a printed film thickness of 25 μm. The unique "sandwich" structure of the working electrode (WE) printed with this ink enhances its electrical conductivity, leading to high sensitivity, selectivity, an
