| 英文摘要 | Flexible high-frequency vibration sensors are highly desirable in various real-world applications such as structural health monitoring, environmental monitoring, and the internet of things. However, developing a facile and effective method to fabricate vibration sensors simultaneously featuring high vibration frequency response-ability and flexibility remains a grand challenge. Herein, we report a flexible ultrahigh-frequency triboelectric vibration sensor (UTVS) prepared by a layer-particle-layer structure. Owing to the flexibility of the materials (i.e., polyethylene terephthalate membrane) and the ultrahigh-frequency vibration response-ability of internal microparticles, the flexible UTVS exhibits an enhanced working frequency range of 3-170 kHz, which is much broader than previously reported triboelectric vibration sensors. Moreover, the UTVS can work not only in a flat state but also in a bent state due to its flexibility and the unique layer-particle-layer structural design. The UTVS shows nanometer-level vibration response-ability, omnidirectional response, stability in the temperature range of 10-70 degrees C, good frequency resolution of 0.01 kHz, and excellent performance in burst vibration detection (e.g., pencil lead break events and impact events from falling steel balls). With a collection of compelling features, the device is successfully demonstrated in vibration monitoring of curved structures (e.g., real-time water pipeline leak monitoring). Such a flexible ultrahigh-frequency triboelectric vibration sensor holds great potential in a wide range of practical applications, such as communication, health care, and infrastructure monitoring. |
