Abstract

Abstract: Bridge health monitoring system can play a role in bridge safety early warning, fatigue diagnosis, and life prediction. However, traditional bridge health monitoring system relies on manpower or battery power supply, which challenges the real-time effectiveness of health monitoring sensors. Herein, we proposed a self-powered bridge health monitoring system based on the elastic origami structure triboelectric nanogenerator (EO-TENG) array. In detail, the self-powered bridge health monitoring system contains the self-powered bridge health data acquisition/processing modular and the NB-IoTs communication modular. The EO-TENG follows an elastic origami structure design and can convert the low-frequency impact vibration energy into multiple frequency current output. With the integrated PMC, the EO-TENG array can provide the stable direct current (DC) voltage on the external load. Furthermore, the EO-TENG array with power management circuit (PMC) and energy storage device can drive the data processing modular to obtain and process vibration signals from piezoelectric patch. The NB-IoTs communication modular can send the vibration information to the terminal. Our design can provide a new system framework for TENG device in the bridge monitoring field. This design will promote the application of TENGs in the bridge monitoring field. Graphical Abstract: ga1 Highlights: To build the self-powered bridge health monitoring system, we designed an elastic origami structure triboelectric nanogenerator (EO-TENG) to harvest impact vibration energy. According to the experimental results, when the impact amplitude and frequency are 2.4 cm and 1 Hz, the instantaneous open circuit voltage ( Voc ) and short-circuit current ( Isc ) of EO-TENG reach 105 V and 58 µA, respectively. The EO-TENG array with PMC and energy storage device can drive the data processing modular to obtain and process vibration signals from the piezoelectric patch. The NB-IoTs communication modular can send the vibration information to the terminal
