Superhydrophobic surfaces repel water and other liquids such as tissue fluid, blood, urine, and pus, which can open up a new avenue for the development of biomedical devices and has led to promising advances across diverse fields, including plasma separator devices, blood-repellent sensors, vascular stents, and heart valves. Here, the fabrication of superhydrophobic liquid–solid contact triboelectric nanogenerators (TENGs) and their biomedical applications as droplet sensors are reported. Triboelectrification energy can be captured and released when droplets are colliding or slipping on the superhydrophobic layer. The developed superhydrophobic TENG possesses multiple advantages in terms of simple fabrication, bendability, self-cleaning, self-adhesiveness, high sensitivity, and repellency to not only water but also a variety of solutions, including blood with a contact angle of 158.6°. As a self-powered sensor, the developed prototypes of a drainage bottle droplet sensor and a smart intravenous injection monitor based on the superhydrophobic liquid–solid contact TENG can monitor the clinical drainage operation and intravenous infusion in real time, respectively. These prototypes suggest the potential merit of this superhydrophobic liquid–solid contact TENG in clinical application, paving the way for accurately monitoring clinical drainage operations and intravenous injection or blood transfusion in the future.

超疏水液固接触摩擦电纳米发生器作为生物医学应用中的液滴传感器。

超疏水表面可以排斥水和其他液体，例如组织液，血液，尿液和脓液，这可以为生物医学设备的开发开辟新的途径，并在包括血浆分离器，驱血剂在内的各个领域带来了可喜的进展传感器，血管支架和心脏瓣膜。在这里，报道了超疏水液固接触摩擦电纳米发生器（TENG）的制造及其作为液滴传感器的生物医学应用。当液滴在超疏水层上碰撞或滑动时，摩擦起电能量可以被捕获并释放。所开发的超疏水TENG在简单制造，可弯曲性，自清洁，自粘性，高灵敏度和对水以及多种溶液的排斥性方面均具有多种优势，包括接触角为158.6°的血液。作为一种自供电传感器，基于超疏水性液-固接触装置TENG的引流瓶液滴传感器和智能静脉注射监测器的原型开发可以分别实时监测临床引流操作和静脉输液。这些原型表明，这种超疏水性液体-固体接触剂TENG在临床应用中具有潜在的优点，为将来准确监测临床引流操作以及静脉注射或输血铺平了道路。开发的排水瓶液滴传感器原型和基于超疏水液固接触的智能静脉注射监测器TENG可以分别实时监测临床引流操作和静脉输液。这些原型表明，这种超疏水性液体-固体接触剂TENG在临床应用中具有潜在的优点，为将来准确监测临床引流操作以及静脉注射或输血铺平了道路。开发的排水瓶液滴传感器原型和基于超疏水液固接触的智能静脉注射监测器TENG可以分别实时监测临床引流操作和静脉输液。这些原型表明，这种超疏水性液体-固体接触剂TENG在临床应用中具有潜在的优点，为将来准确监测临床引流操作以及静脉注射或输血铺平了道路。
