滴液是化学中最常见的操作之一，但很少有人认为液体与空气接触会在液体中引入电荷，从而影响化学反应。在这里，我们提出了一个功能滴通道的基础上，液体摩擦纳米发电机（L-TENG），有效地收集能量的液滴和感测它们的运动。L-TENG是光栅电极L-TENG和单电极L-TENG的混合，分别用于能量收集和传感。当从漏斗中滴落时，液滴的能量可以被连续地收集和存储。同时，单电极L-TENG可以识别液体流动的时间间隔和液滴数量，提供化学过程的信息。具有增强的能量收集和传感功能的装置在智能实验室系统中应该具有很大的应用前景，并且还可以有助于L-TENG用于收集液滴能量的优化。
Dripping liquid is one of the most common practices in chemistry, but one rarely thinks that the contact of liquid with air could introduce charges in the liquid, which may affect the chemical reaction. Here, we propose a functional dripping channel based on a liquid triboelectric nanogenerator (L-TENG) to effectively harvest energy from liquid droplets and sense their motion. The L-TENG is a hybrid of a grating-electrode L-TENG and a single-electrode L-TENG, which are for energy harvesting and sensing, respectively. When dripping from a funnel, the energy of the droplets can be successively harvested and stored. Meanwhile, the single-electrode L-TENG can identify the time interval for the liquid flow and the number of droplets, providing information on the chemical process. The device with enhanced energy harvesting and sensing functions should have great application prospects in intelligent laboratory systems and can also contribute to the optimization of the L-TENGs for harvesting liquid droplet energy.
