An electrochemiluminescence (ECL) analytical device was developed using an electric contactless power transfer system. A mutually induced electromotive voltage was generated by wrapping an enameled wire around a commercial contactless charger. There was no electrical contact between the power supply and the electrochemical cell. For the tris(2,2′-bipyridine)ruthenium(II) (Ru(bpy)₃²⁺)/tri-n-propylamine system, a weak ECL signal was observed. When an inexpensive rectifier diode was introduced between the coil and the working electrode, the ECL intensity detection sensitivity increased by more than 100 times. The relationship between the waveform of the applied voltage and the ECL response was clarified, and the optimum conditions were determined. The intensity of the induced electromotive voltage was easily controlled by changing the number of turns in the coil. The proposed method is a safe, simple, and inexpensive technique without electrical contact.

使用非接触式电力传输系统开发了电化学发光 (ECL) 分析装置。将漆包线缠绕在商用非接触式充电器上会产生相互感应的电动势。电源和电化学电池之间没有电接触。对于三(2,2'-联吡啶)钌(II) (Ru(bpy) ₃ ²⁺ )/tri- n-丙胺系统，观察到微弱的 ECL 信号。当在线圈和工作电极之间引入廉价的整流二极管时，ECL 强度检测灵敏度提高了 100 倍以上。明确施加电压的波形与ECL响应之间的关系，并确定最佳条件。通过改变线圈的匝数很容易控制感应电动势的强度。所提出的方法是一种安全、简单且廉价的技术，无需电接触。
