“…Instead of directly using the impinges of shedded vortices on the piezoelectric membrane or cantilever to induce mechanical oscillations, Wang and his coworkers [51][52][53]84] developed energy harvesters in the form of a flow channel with a flexible diaphragm. The diaphragm was driven into vibration by vortex shedding from a bluff body placed in the channel.…”

The concept of harvesting ambient energy as an alternative power supply for electronic systems like remote sensors to avoid replacement of depleted batteries has been enthusiastically investigated over the past few years. Wind energy is a potential power source which is ubiquitous in both indoor and outdoor environments. The increasing research interests have resulted in numerous techniques on small-scale wind energy harvesting, and a rigorous and quantitative comparison is necessary to provide the academic community a guideline. This paper reviews the recent advances on various wind power harvesting techniques ranging between cm-scaled wind turbines and windmills, harvesters based on aeroelasticities, and those based on turbulence and other types of working principles, mainly from a quantitative perspective. The merits, weaknesses, and applicability of different prototypes are discussed in detail. Also, efficiency enhancing methods are summarized from two aspects, that is, structural modification aspect and interface circuit improvement aspect. Studies on integrating wind energy harvesters with wireless sensors for potential practical uses are also reviewed. The purpose of this paper is to provide useful guidance to researchers from various disciplines interested in small-scale wind energy harvesting and help them build a quantitative understanding of this technique.

This article presents an overview on the state of the art of Tyre Pressure Monitoring System related technologies. This includes examining the latest pressure sensing methods and comparing different types of pressure transducers, particularly their power consumption and measuring range. Having the aim of this research to investigate possible means to obtain a tyre condition monitoring system (TCMS) powered by energy harvesting, various approaches of energy harvesting techniques were evaluated to determine which approach is the most applicable for generating energy within the pneumatic tyre domain and under rolling tyre dynamic conditions. This article starts with an historical review of pneumatic tyre development and demonstrates the reasons and explains the need for using a tyre condition monitoring system. Following this, different tyre pressure measurement approaches are compared in order to determine what type of pressure sensor is best to consider in the research proposal plan. Then possible energy harvesting means inside land vehicle pneumatic tyres are reviewed. Following this, state of the art battery-less tyre pressure monitoring systems developed by individual researchers or by world leading tyre manufacturers are presented. Finally conclusions are drawn based on the reviewed documents cited in this article and a research proposal plan is presented.

“…Output power and voltage achieved are 0.1 mW and 0.8 V, respectively. A reported piezoelectric energy harvester [25] is capable of generating electricity from vibrations induced by fluid flow. These vibrations cause up and down motion of the piezoelectric layer at a pressure of 0.3 kPa and frequency of 52 Hz, producing 120 mV p-p and 0.7 nW as output voltage and power, respectively.…”

This work presents modeling, simulation, fabrication, and testing of a novel flow-based electromagnetic energy harvester (F-EMEH) for producing usable electrical energy from the pulsating fluid pressure levels within the pipeline. The power produced by the developed harvester can be effectively utilized for the operation of the wireless monitoring system of pipeline networks. The devised F-EMEH harvester consists of a stationary magnet positioned in the upper cap of the harvester and directly facing the wound coil that is fixed to a flexible latex membrane. The membrane along the coil when exposed to the pulsating fluid flow in the pipeline oscillates with respect to the stationary magnet. This relative motion of the membrane induced the voltage across the coil terminals. The harvester when applied to a pressure amplitude of 625 Pa generated an open circuit voltage of 1.2 V and a maximum load power of 18.6 μW when connected to 4.3 Ω load. Furthermore, when integrated to a voltage rectifier, an open circuit output of 4 V DC is achieved by the device at a pressure of 625 Pa. In addition, with the developed prototype, a 3.6 V, battery is charged up to 3.2 V within 30 min of duration. The voltage and power levels attained by the energy harvester can provide an easy solution for powering wireless sensor nodes mounted on a pipeline network for condition monitoring.
