description	Pursuing a higher response signal is the core challenge in improving the detection performance of a microelectrode-based amperometric electrochemical sensor. Band microelectrode arrays (bMEAs) are attractive due to their high response current and economical fabrication process. However, further amplifying the response current by arranging the array more compactly or increasing its size is generally hindered by the shielding effect or the restricted construction region. A novel array of sinuous band microelectrodes (sbMEA) is proposed, produced by deforming a bMEA by tilting and bending. Its response and diffusion characteristics are simulated and analyzed. The effects of structural parameters on its performance are revealed, and their optimal value is deduced. The simulation demonstrates that a sbMEA can generate a larger current than a MEA of traditional shape. Production of such a sbMEA does not involve any additional fabrication costs compared with a bMEA. Cyclic voltammetry (CV) tests with potassium ferrocyanide solution verify the theoretical performance of the sbMEA, and a 10% higher current was obtained compared to the corresponding bMEA.
