“…Spontaneous synchronization is a phenomenon in which a number of coupled dynamical systems self-organize to behave consistently over time. Synchronization phenomena are observed in various physical, chemical, and biological systems over a wide range of spatial and temporal scales (see, for example, [ 1 , 2 , 3 , 4 , 5 , 6 ]). The concept of synchronization is especially important in the design of nanoscale devices since there is often a need to amplify the weak output signals from individual molecular-size functional units while maintaining the high sensitivity of the device to weak stimuli.…”

The intensive development of nanodevices acting as two-state systems has motivated the search for nanoscale molecular structures whose long-term conformational dynamics are similar to the dynamics of bistable mechanical systems such as Euler arches and Duffing oscillators. Collective synchrony in bistable dynamics of molecular-sized systems has attracted immense attention as a potential pathway to amplify the output signals of molecular nanodevices. Recently, pyridine-furan oligomers of helical shape that are a few nanometers in size and exhibit bistable dynamics similar to a Duffing oscillator have been identified through molecular dynamics simulations. In this article, we present the case of dynamical synchronization of these bistable systems. We show that two pyridine-furan springs connected by a rigid oligomeric bridge spontaneously synchronize vibrations and stochastic resonance enhances the synchronization effect.

“…Additionally, the EH performance drops dramatically when the operating frequency deviates from the resonance point [13]. In order to broaden the operating frequency band of a PEH, various solutions have been proposed, mainly including energy harvester array (EHA) methods [14,15,16,17], nonlinear energy harvester (NEH) methods [18,19,20,21,22,23] and inherent frequency adjustment (IFA) methods [24,25,26,27,28,29,30,31]. Based on EHA methods: arraying energy harvesters with different inherent frequencies is the easiest way to obtain a broadband PEH system.…”

“…However, EHA is limited in continuous frequency adjustment and the power density of EHA is quite low [17]. Based on NEH methods: the NEH has wide and steady bandwidth [18,19]. Shi et al [20] proposed an ultra-low frequency zigzag based PEH, which has the potential of low-power electronic devices powering.…”

This letter proposes a broadband piezoelectric energy harvesting (PEH) system based on sensorless direct resonance tuning (SDRT) technique. The PEH system consists of a frequency-tunable harvester, an energy harvesting (EH) subsystem and a control subsystem. The EH subsystem can transfer energy from the harvester to the storage. The control subsystem can detect the ambient vibration frequency and adjust the inherent frequency of the harvester using a servo motor to match the ambient vibration. Furthermore, the vibration frequency detection is based on the harvester itself rather than an additional sensor. Finally, the experimental results show that the prototyped PEH system can adjust its inherent frequency to achieve resonance in the range of 36-50 Hz. In addition, the EH performance achieved by the proposed SDRT technique can reach at least 77.6% of the manual frequency tuning method.
