“…PEHs supply ac power with significant output impedance; consequently, an interface circuit (IC) is required to efficiently extract and convert piezoelectric ac voltage to usable dc voltage. Two conventional rectifiers, full-bridge rectifier and voltage doubler are the most common ac-dc converters, which have been demonstrated in several works [9], [10]. Passive and active rectifiers [11], [12] suffer from low extraction efficiency due to significant power losses during intermittent vibrations.…”

This paper presents a self-powered interface circuit to extract energy from ambient vibrations for powering up microelectronic devices. The circuit interfaces a piezoelectric energy harvesting micro electro-mechanical systems (MEMS) device to scavenge acoustic energy. Synchronous electric charge extraction (SECE) technique is deployed through the implementation of a novel multistage energy extraction (MSEE) circuit in 180 nm HV CMOS technology to harvest and store energy. The circuit is optimized to operate with minimum power losses when input power is limited, and adapts well to operating conditions with higher input power. The highly accurate peak detector was validated for a wide piezoelectric frequency range from 20 Hz to 4 kHz. A charging efficiency of about 84% has been achieved for 4.75 V open-circuit piezoelectric voltage excited at 390 Hz input vibration under nominal input power range of 30-80 µW. Power optimizations enable the circuit to maintain a conversion efficiency of 47% at input power level as low as 3.12 µW. MSEE provides up to 15% efficiency improvement compared to traditional SECE, and maintains power efficiency as high as possible for a wide input power range. Index Terms-Interface circuit (IC), multistage energy extraction (MSEE), piezoelectric energy harvester (PEH), power efficiency, self powered, vibration.

“…A piezoelectric transducer can be modeled as electrical equivalent circuit having a sinusoidal current source (I) in parallel with a large value of resistance (RP) and internal electrode capacitance (CP) under self-resonant frequency range [18,19], as shown in Figure (1). A vibrating piezoelectric transducer normally generates an AC voltage, which in turn has to be converted into DC for battery charging.…”

Energy harvesting is expected to be used as a source of energy for tiny low power sensor nodes. Since the amount of harvested energy is unstable, an energy storage device is used with an energy harvesting system. With advancement in rechargeable batteries, ultra-low weight rechargeable lithium-ion batteries are used as energy storage devices with low power wireless sensor nodes at remote places. These ultra-low weight energy storage devices are expected to be charged efficiently with maximum harvested power. The mismatching of the electrical impedance between input (i.e. Piezoelectric Transducer (PZT)) and output (i.e. Load) gives inefficient power transfer. The piezoelectric energy harvesting circuit described in this paper focuses on the design and analysis of op-amp based inductor circuit for matching the impedance by presenting a conjugate impedance match to the Piezoelectric harvester. The values of inductor obtained for optimal power transfer from PZT to storage device tend to be prohibitively large. This becomes an inhibiting factor for Integrated Circuit(IC) realization of the interface circuits. The proposed work implements the required value of inductor using op-amp circuit to match the complex conjugate part of the impedance thereby making it cost effective and suitable for IC realization. Finally, comparison between pure resistive match and complex conjugate match is presented along with results.

Nowadays renewable energy sources play a significant role in the energy harvesting. For the past decade various energy harvesting methods have been discussed by researchers for capturing the energy from different sources. From the survey, one of the most prominent methods is the use of piezoelectric transducers for harvesting the energy. It is known that piezoelectric energy harvesting is the easiest method of energy harvesting from the various sources available such as human walking, dancing etc. Therefore this method can be implemented in system for wide variety of applications. The piezoelectric transducer AC output is of very low voltage and power and hence insufficient to drive any electrical application. Most of the small scale electrical application generally runs on the DC voltage, therefore the AC voltage obtained from the piezo transducer vibration is rectified using rectifiers to generate DC voltage. Thus in this paper, a modified rectifier AC/DC converter with the combination of an inductor is placed in the rectifier, which enhances the voltage and power from the rectifier output. In order to enhance the voltage rating, a DC/DC converter has been added at the end of a rectifier circuit. From the simulation results the proposed circuit modified rectifier has improved the output voltage as well as output current by 10.19 volts and 0.1019 amps respectively for input voltage of 5V. When compared with conventional rectifier circuit.
