“…This SSHI technique can be implemented with many configurations, which are called parallel SSHI, series SSHI and Synchronous Electric Charge Extraction (SECE). Recently some other groups [4][5] have proposed innovative schemes leading to better performance. Each of these configurations is defined by the relative position of the pair switch-inductor.…”

Abstract. In this paper, the design, implementation and testing of a prototype for electric energy generation from collecting wasted ambient power sources coming from the mechanic vibrations (Piezoelectric Energy Harvesting PEH) is presented. This prototype has been specifically designed for applications where it is required to connect multiple transducers in order to obtain greater power levels. This design is based on a previous comparative analysis among all the existing auto-harvesting circuits. The prototype has been tested both in laboratory tests as in real field trials on board railway units, with encouraging results. It has been proved that, though achieving power levels of a few milliwatts, its application in the autonomous low-consumption devices powering systems field is a real possibility.

“…Mehraeen et al 13 have demonstrated that tapered cantilever beams are more effective in generating uniform strain profile over rectangular and trapezoidal beams and resulting in increased harvested power. The harvested energy from the piezoelectric energy harvester is maximized by varying the thickness of the beam along its length which produces more uniform strain distribution along piezoelectric element length.…”

This paper presents a cantilever structure as energy harvester by introducing a trapezoidal cavity to increase the amplitude of the generated voltage and the overall mechanical to electrical energy conversion efficiency. An analytical model of the proposed structure is developed using Euler-Bernoulli beam theory. The effect of taper angle of the trapezoidal cavity and the neutral axis shift on the generated voltage is analyzed using analytical model and through experimentation. The generated output voltage from the energy harvester with trapezoidal cavity is compared with the beam having rectangular cavity and the beam without cavity. The generated voltage for the beam with trapezoidal cavity is 97.5% and 108% higher as compared with the beam having rectangular cavity and the beam without cavity. The characteristics of the energy harvester are evaluated through analytical model and experimentation and the results are in close agreement.

“…It has a competent control circuit to adjust the output voltage generated from rectifier. In PZT, the direct connection to the load is not recommended to increase the power harvested (Mehraeen et al, 2010). Therefore, they suggested an efficient stand-alone of energy harvesting circuit consist of a PZT cantilever beam, rectifier, voltage inversion circuitry and power converter.…”

This research work presents an Ultra-Low-Power (ULP) Hybrid Micro Energy Harvester (HMEH) for biomedical application. This architecture uses the inputs of Thermoelectric Generator (TEG) and body vibration. TEG is based on temperature gradient between the ambient environment and human body. While vibration is based on the vibrate sources like motor that is able to generate an AC voltage. Having two sources overcome the issue of limitation caused by single source harvester but will result in impedance mismatching among the desired sources. The proposed of HMEH architecture consists of a control manager with Asynchronous Finite State Machine (AFSM) to grab the proper input value, a rectification to convert vibration input from AC to DC, a start-up to initialize the desired input, a Maximum Power Point Tracking (MPPT) to achieve maximum power extraction, a boost converter to boost up the input voltage, energy storage to keep the energy and voltage regulator to fix or produce the desired output voltage. A single power management circuit is used to reduce the number of components used and power losses. The HMEH will be modeled, designed and simulated using PSPICE software and then implement in 0.13 µm CMOS technology. Next, the developed HMEH will be coding using Verilog Hardware Description Language (VHDL) under mentor graphics and then download to Field Programmable Gate Array (FPGA) for real time implementation. The expectation from this ULP HMEH is to achieve 2.0-4.0 V of regulated voltage output from input sources range of 80-600 mV at start-up with an efficiency of 93%.
