Tóm tắt

Notwithstanding the significant advancements in the fabrication of flexible sensors capable of continuously detecting glucose levels in the human body, using conventional manufacturing techniques to create flexible sensors with excellent sensitivity at a low cost is still difficult. This paper introduces a low-cost, high-sensitivity glucose sensor (CoS/LPEG) that is prepared by combining liquid-phase exfoliated graphene (LPEG) and cobalt sulfide (CoS) for the first time through Inkjet printing. The glucose sensor demonstrates two linearity ranges in the glucose concentration ranges of 0.002-6.57 mM and 6.57-13.32 mM in NaOH, with sensitivities of 1046 μA mM
