“…The energy efficiency decreases rapidly when the frequency spectrum of the vibrations shifts out of the resonator's optimal point of operation. Energy harvesting from high-amplitude friction-induced vibrations (FIV) was proposed recently [3]. Even though friction-excited systems are well known to exhibit rich periodic and chaotic dynamic behavior [4], most systems show high vibration energy shares in narrow frequency ranges.…”

This work demonstrates preliminary results on energy harvesting from a linearly stable fluttertype system with circulatory friction forces. Harmonic external forcing is applied to study the energy flow in the steady sliding configuration. In certain parameter ranges negative excitation work is observed where the external forcing allows to pull part of the friction energy out of the system and thus makes energy harvesting possible. Studies reveal that this behavior is largely independent of the flutter point and thus that it is primarily controlled by the excitation. Contrary to existing energy harvesting approaches for such systems, this approach uses external forcing in the linearly stable regime of the oscillator which allows to control vibrations and harvest energy on demand.

“…Generally, five main techniques can realize the conversion of vibration energy to electric energy, i.e., electromagnetic, electrostatic, piezoelectric, magnetostrictive, and triboelectric [8][9][10][11][12][13][14]. All these techniques have been successfully demonstrated experimentally and numerically in the past.…”

In this work, piezoelectric energy harvesting (PEH) performance via friction-induced vibration (FIV) is studied numerically. A nonlinear two-degree-of-freedom friction system (mass-on-belt) with piezoelectric elements, which simultaneously considers the stick-slip motion, model coupling instability, separation, and reattachment between the mass and belt, is proposed. Both complex eigenvalue analyses and transient dynamic analysis of this nonlinear system are carried out. Results show that it is feasible to convert FIV energy to electrical energy when the friction system is operating in the unstable vibration region. There exists a critical friction coefficient (μc) for the system to generate FIV and output visible voltage. The friction coefficient plays a significant role in affecting the dynamics and PEH performance of the friction system. The friction system is able to generate stronger vibration and higher voltage in the case that both the kinetic friction coefficient and static friction coefficient are larger than μc. Moreover, it is seen that the separation behavior between contact pair can result in overestimating or underestimating the vibration magnitude and output voltage amplitude, and the overestimate or underestimate phenomenon is determined by the located range of friction coefficient. Furthermore, it is confirmed that an appropriate value of external resistance is beneficial for the friction system to achieve the highest output voltage. The obtained results will be beneficial for the design of PEH device by means of FIV.

“…On the other hand, the fast development of wireless technology and micro-electromechanical systems (MEMS) offers many portable low-power applications that could be widely used in daily life. Considering the limited lifetime of batteries and challenges of battery replacement (recharging), self-powered applications using ambient energy harvesting have been studied in recent years [4,5]. Some examples of energy sources suitable for energy harvesting are solar, vibration, thermal, and bio-fuel sources.…”

This paper proposes a new Unified Switch Fault Diagnosis (UFD) approach for two-stage non-isolated DC-DC converters used in energy harvesting applications. The proposed UFD is compared with a switch fault diagnosis consisting of two separate fault detection algorithms, working in parallel for each converter. The proposed UFD is simpler than the two parallel fault diagnosis methods in realization. Moreover, it can detect both types of switch failures, open circuit and short circuit switch faults. It can also be used for any two-stage non-isolated DC-DC converters based on two single switch converters, no matter the converter circuits in each stage. Some selected simulation and Hardware-in-the-Loop (HIL) experimentation results confirm the validity and efficiency of the proposed UFD. Also, the proposed UFD is applied successfully for fault-tolerant operation of a buck/buck–boost two-stage converter with synchronous control and a redundant switch.
