Original abstract
The rapid development in the field of the Internet of Things (IoT) has paved the way for integration of wireless low-power electronic sensors, typically in the range of milli to micro watt in Structural Health Monitoring (SHM) systems.Energy harvesting of ambient sources present in the SHM systems' environment can potentially generate enough power to target wireless sensor autonomy. Vibrations are an energy source found in abundance in civil engineering structures, such as a bridge, due to various reasons including environmental phenomena, traffic load and human activities. While piezoelectric and electromagnetic energy harvesters are employed to real-world applications such as powering-up sensors deployed in bridges and in marine buoys respectively, Triboelectric Nanogenerators (TENGs) are attracting significant attention due to their cost effectiveness, high conversion efficiency and wide material versatility. This makes TENGs suitable for creating cheap and efficient low-frequency vibration energy harvesters. In this work, a novel architecture of a contact-separation freestanding tribolayer TENG (CFTENG) is demonstrated. In a low frequency (2 Hz) and a low amplitude environment (5 μm) the CFTENG was able to demonstrate an open-circuit voltage of 213.9 V. When connected to an optimal resistance of 50 MΩ, an output voltage of 104.49 V a short-circuit current of 2.09 μA, a peak power of 115.3 μW and energy per contact separation of 3.09 μJ were observed. The results demonstrate that the CFTENG offers a reliable and cost effective alternative solution to harvest energy from low-frequency vibrations and act as a sustainable power source for low-power SHM sensor nodes. The integration of TENGs in a SHM sensor node enables the development of a reliable, cost effective alternative solution lays the groundwork for autonomous self-powered SHM systems.
