The triboelectric nanogenerator (TENG) has been investigated intensively during the last decade in terms of power improvement and application as sensors, however, its voltage is usually too high and spike-like to be used directly as a power source for electronic devices. Although there was an effort to adjust the voltage through the circuit design, the complexity and the bulkiness of the circuit board make it difficult. Here, we propose a simple approach to change the spike-like voltage profiles to square-like profiles and adjust the output voltage to be suitable range for electronics. We used printed ion gel electrolyte patterns as capacitors and investigated the effects of dimension of the capacitor, connection types (serial, parallel) of multiple capacitors, and electrochemical conditions. The voltage profile of the TENG-ion gel system was modulated by the contact frequency applied to the TENG, the contact area of the ion gel with the electrode, the type of ions in the electrolyte, reduction/oxidation reaction in the gel, and the connection type (parallel, series) between ion gel patterns. We successfully demonstrated the light emission of a large number of printed electrochemiluminescence patterns.

在过去的十年中，摩擦电动纳米发电机（TENG）已在功率改进和作为传感器的应用方面进行了深入研究，但是，其电压通常过高且呈尖峰状，无法直接用作电子设备的电源。尽管已经努力通过电路设计来调节电压，但是电路板的复杂性和体积使其变得困难。在这里，我们提出了一种简单的方法来将尖峰电压轮廓更改为方形轮廓，并将输出电压调整为适合电子产品的范围。我们使用印刷的离子凝胶电解质图案作为电容器，并研究了电容器尺寸，多个电容器的连接类型（串行，并联）以及电化学条件的影响。TENG离子凝胶系统的电压曲线受施加到TENG的接触频率，离子凝胶与电极的接触面积，电解质中离子的类型，凝胶中的还原/氧化反应以及离子凝胶图样之间的连接类型（平行，串联）。我们成功地证明了许多印刷的电化学发光图案的发光。
