A simple cell has some essential features ... The zinc is higher in the electrochemical series, so it pushes electrons towards the copper. \(Zn(s) \to Zn_{}^{2 + }(aq) + 2e_{}^ ...
"We have demonstrated a simple yet powerful technique to amplify weak bioelectronic signals using OECTs, overcoming previous challenges in integrating fuel cells with electrochemical sensors ...
