“…Energy harvesting based on nonlinear resonators can provide more efficient ambient energy converters for various frequencies [1][2][3][4] comparing to linear devices [5]. The role of nonlinearities [6] is important not only in broadening of frequency in the main resonance region but also in involving the subharmonic and superharmonic frequencies in multiple solutions.…”

Abstract. We examine the response of an inverted pendulum excited harmonically with amplitude limiters. Such a nonlinear resonator is suggested to work in the transduction of ambient vibration energy into the electrical power through bending of the moving beam. Using a multibody model we follow rotation and bending of the elastic beam and we provide the solutions of various frequencies. We found that the corresponding bending is the largest for subharmonic solutions of beam oscillations.

“…Piezoelectric vibration energy harvesting from ambient sources is a promising technology for distributed power generation of small autonomic devices such as wireless sensor networks and recharging batteries [1][2][3][4]. Much research effort has focused upon the refinement of devices operating in the linear mode and some commercial devices are available.…”

Abstract. In this paper we examine in detail the multiple responses of a novel vibrational energy harvester composed of a vertical bistable beam whose complex non-linear behavior is tuned via magnetic interaction. The beam was excited horizontally by a harmonic inertial force while mechanical vibrational energy is converted to electrical power through a piezoelectric element. The bistable laminate beam coupled to the piezoelectric transducer showed a variety of complex responses in terms of the beam displacement and harvested power output. The range of vibration patterns in this non-linear system included single-well oscillations and snap-through vibrations of periodic and chaotic character. Harvested power was found to be strongly dependent on the vibration pattern with nonlinearities providing a broadband response for energy harvesting. Wavelet analysis of measured voltage, displacement and velocity time histories indicated the presence of a variety of nonlinear periodic and also chaotic phenomena. To measure the complexity of response time series we applied phase portraits and determine stroboscopic points and multiscale entropy. It is demonstrated that by changing parameters such as the magnetic interaction, the characteristics of the bistable laminate harvester, such as the natural frequency, bandwidth, vibration response and peak power can be readily tailored for harvesting applications.

“…There have been a number of attempts to broaden the frequency response of vibration energy harvesters by introducing elastic non-linearities into the harvesting system [2][3][4][5]. This includes the design of bistable structures which exhibit two specific energy wells and can oscillate between two stable states.…”

“…This includes the design of bistable structures which exhibit two specific energy wells and can oscillate between two stable states. Methods to generate bistability include the use of repulsive or attractive magnetic interactions between a cantilever and an external magnet, axial loading and the use of post-buckled beams [4].…”

Dynamics of a vibrational energy harvester with a bistable beam: voltage response identification by multiscale entropy and “0-1” test

Abstract. The use of bistable laminates is a potential approach to realize broadband piezoelectric-based energy harvesting by introducing elastic non-linearities to the system. In this paper the dynamic response of a piezoelectric material attached to a bistable laminate beam is examined based on the experimental measurement of the generated voltage-time series. The system was subjected to harmonic excitations and exhibited single-well and snap-through vibrations of both periodic and chaotic character. The ability to identify the vibration modes of the energy harvester is important since different levels of power are expected in each dynamic mode. We identify the dynamics of the selected system response using return maps, multiscale entropy, and "0-1" test. The potential of the approaches to identify periodic and chaotic modes and snap-through events in the non-linear bistable harvester is described.
