Abstract
High-fidelity sensing remains highly challenging in self-powered systems, as the limited power of energy harvesters constrains data acquisition and transmission. In this work, we present a wireless, intelligent, self-powered environmental node (WISE-Node) that simultaneously harvests energy and collects sensing information from ambient vibrations. Its multi-contact triboelectric vibration energy harvester (MC-TVEH) achieves an ultra-wide bandwidth of 10–300 Hz, delivering peak and RMS power densities of 13.42 kW/m3and 1.73 kW/m3, respectively. The WISE-Node also functions as a broadband sensor, accurately tracking excitation frequencies via FFT analysis (R2 = 0.9997 across 3–10,000 Hz). Using a Random Forest classifier on the acquired data, the WISE-Node identifies flange conditions with 99.38% accuracy. Field tests on marine engines and generators validate its robust performance, achieving a cold start in just 28.8 s and maintaining fully self-powered 1000 Hz sampling and stable wireless transmission. These results highlight the proposed WISE-Node’s strong potential for self-sustained high-fidelity sensing, thereby advancing next-generation battery-free industrial IoT and digital twin technologies.

Continuous electrochemical monitoring can provide information that is missed by intermittent sampling, but its practical use is often limited by the energy required for sensing, processing, and wireless communication. Greater autonomy therefore requires the sensing method, measurement schedule, and energy source to be...
