We report on a cheap and flexible potassium ion sensor based on a screen-printing process. The as-obtained ion sensor shows a sensitivity of 59.16 mV/dec close to the Nernstian behavior and retains its original sensitivity even in a bent state. It shows fast response time, no hysteresis effect, and good durability, indicating a high electrochemical sensing performance. The potassium ion sensor has a good selectivity to selectively detect potassium ion in the presence of different cations. The results of detecting potassium ion in actual sports drink using our sensor are consistent with those of the commercially available potassium ion meter. |
