摘要

具有振动膜层的超声驱动摩擦电纳米发电机(USD-VM-TENG)是一种很有前途的自供电宽带超声传感器。然而,现有设计固有的高检测限(DL)限制了更广泛的应用。此外,对膜层超声驱动振动特性(USD-VC)的不完全了解也阻碍了对器件性能的深入了解和进一步优化。本研究首次采用三维动态激光扫描技术,实验揭示了膜层的宽带USD-VC,指导了无腔USD-VM-TENG (CF-USD-VM-TENG)的创新设计。尽管通常认为不适合用于teng的接触分离模式,但无腔结构消除了超声波驱动的接触过程,使接触带电不依赖于超声波激励。因此,这种设计非常好地适应了膜层在宽广的超声频率范围内的各种高阶振动行为,与传统的具有腔结构的usd - vm - teng相比,该设备的平均DL大大降低了1-2个数量级。优化的CF-USD-VM-TENG实现了超低的DL,低至37.1 Pa@20 kHz。其校准的宽带输出特性和0.001 kHz的优越频率分辨率为该设备的进一步发展提供了宝贵的见解。此外,它可以实现高达25 MHz的工作频率,以及工作稳定性和耐用性(20天内1亿次循环)。CF-USD-VM-TENG通过检测和识别低强度宽带超声波信号,成功地扩展了teng的超声波传感应用。这项工作为进一步推进TENGs在超声相关领域的应用铺平了道路。

Self-powered wideband ultrasonic sensor based on capacitive triboelectric technology with ultralow detection limits and superior frequency resolution

Self-powered wideband ultrasonic sensor based on capacitive triboelectric technology with ultralow detection limits and superior frequency resolution
The ultrasound-driven triboelectric nanogenerator with a vibratory membrane layer (USD-VM-TENG) has emerged as a promising self-powered wideband ultrasonic sensor. However, the inherent high detection limit (DL) of existing designs constrains broader applications. Furthermore, an incomplete understanding of the membrane layer’s ultrasound-driven vibration characteristics (USD-VC) hinders deeper insights into the device’s performance and further optimization. In this study, 3D dynamic laser scanning technology is applied to experimentally reveal the broadband USD-VC of the membrane layer for the first time, guiding the innovative design of a cavity-free USD-VM-TENG (CF-USD-VM-TENG). Despite being generally deemed unsuitable for the contact-separation mode of TENGs, the cavity-free structure eliminates the ultrasound-driven contact process and enables contact electrification independently of ultrasonic excitation. As a result, this design adapts exceptionally well to the membrane layer's diverse higher-order vibration behaviors across a broad ultrasonic frequency range, substantially reducing the device's average DL by 1–2 orders of magnitude compared to conventional USD-VM-TENGs with cavity structures. The optimized CF-USD-VM-TENG achieves an ultralow DL down to 37.1 Pa@20 kHz. Its calibrated wideband output characteristics and superior frequency resolution of 0.001 kHz offer valuable insights for the device’s further development. Furthermore, it enables an operating frequency up to 25 MHz, along with operating stability and durability (100 million cycles over 20 days). The CF-USD-VM-TENG is successfully demonstrated to extend the ultrasonic sensing applications of TENGs by enabling the detection and recognition of low-intensity, broadband ultrasonic signals. This work paves the way for further advancements of TENGs in ultrasound-related applications.
