“…The last decade has seen a growing interest in new energy scavenging sources that could replace chemical batteries (Schlichting et al, 2012), such as microbial fuel cells (Wanderoild et al, 2018), solar energy harvesters (Raghunathan et al, 2005), or thermal generators (Sodano et al, 2007). Mechanical energy harvesting is a good way to harvest the ambient energy, especially in closed confined environments.…”

One of the main challenges in energy harvesting from ambient vibrations is to find efficient ways to scavenge the energy, not only at the mechanical system resonance, but on a wider frequency band. Instead of tuning the mechanical part of the system, as usually proposed in the state of the art, this paper develops extensively the possibility to tune the properties of the harvester using the electrical interface. Due to the progress in materials, piezoelectric harvesters can exhibit relatively high electromechanical coupling: hence, the electrical part can now have a substantial influence on the global parameters of the piezoelectric system. In order to harness the energy efficiently from this kind of generator on a wide frequency band, not only the electrical load's effect on the harvester's damping should be tuned, but also its effect on the harvester's stiffness. In this paper, we present an analytical analysis of the influences of the resistive and reactive behavior of the electrical interface on highly coupled piezoelectric harvesters. We develop a normalized study of the multiphysic interactions, reducing the number of parameters of the problem to a few physically meaningful variables. The respective influence of each of these variables on the harvesting power has been studied and led us to the optimal electrical damping expression and the influences of the damping and of the coupling on the equivalent admittance of the piezoelectric energy harvester (PEH). Finally, we linked these normalized variables with real reactive load expressions, in order to study how a resistive, capacitive and inductive behaviors could affect the global performances of the system. The theoretical analysis and results are supported by experimental tests on a highly coupled piezoelectric system (" = 23%). Using an adequate tuning of a RC load at each frequency, the maximum harvested power (11) under a small acceleration amplitude of 0.5. 0" is reach over a 14Hz large frequency band around 105Hz which has been predicted by the model with less than 5% error.

“…2) The topic of multi-source energy harvesting has gained the attention of researchers [21], [22] with the potential to provide a more robust system solution. If the energy arrivals from different sources are (a) independent, (b) Poisson, and (c) energy arrival from each source corresponds to the same amount of energy, then the combined energy arrival process is again Poisson.…”

Energy harvesting communication systems provide a "green" solution by obtaining energy from ambient sources, such as sunlight or vibrations. This energy is stored for transmission of data packets which arrive at the link layer of an energy harvesting transmitter. Since the data and energy arrival processes are independent and random, the data packets wait in a queue for the accumulation of sufficient amount of energy and for service completion of previously arrived packets. Thus, the energy arrival process and the data service process jointly impact the data queue dynamics. This makes the queueing analysis of an energy harvesting communication system challenging. In this paper, we formulate a two stage virtual queueing system which decouples the wait stages for the energy arrival process and the service process. This virtual queueing system leads to closed-form expressions for the average packet delay and the probability of data packet loss due to buffer overflow. We assume that the data and energy arrivals are independent Poisson processes and the service time for data packets may have any general distribution. The expressions for the average packet delay and the probability of buffer overflow are shown to be exact when the service time becomes negligible, and the packet delay gets dominated by data packets waiting for arrival of sufficient energy. These expressions are compared with Monte Carlo simulations and are shown to be robust even when the service time is increased up to sixty percent of the average packet delay.

“…The single-source has to be improved to become a multi-source piezoelectric energy harvester to enhance the total power extraction. Multi-source piezoelectric extracts power from the environment, applying several connected piezoelectric transducers into a single output [9,15], [26][27][28][29][30][31]. A multi-source piezoelectric energy harvester requires an appropriate configuration to optimize the power extraction performance of the harvester.…”

This paper presents the connection configuration of a multi-source piezoelectric transducer to extract energy from ambient mechanical forces to power up electronic devices. The configurations are optimized by applying a full-bridge rectifier (FBR) as an interface circuit to complete alternating to direct current (AC-DC) transformation before powering up any electronic devices. The FBR is varied in Silicon (Si-FBR) and Schottky (So-FBR) diodes to compare which one is more efficient. Six pieces of 35 mm piezoelectric transducer, PT, are connected in parallel and series connection then pressed under 20 N periodic force. The study shows that the configuration types of the multi-source PT have different results in harvesting mechanical energy. Experimental results show the maximum power can be harvested from six PTs in series for one and six Si-FBRs are 440 and 500 µW, respectively and for So-FBR obtained 150 and 730 µW. In a parallel configuration, maximum power can be harvested from six PTs for one and six Si-FBRs are 440 and 1050 µW, respectively and for So-FBR obtained 780 and 902 µW.
