Abstract

Vibration-based energy harvesters with multi-layer piezoelectrets (ferroelectrets) are presented. Using a simple setup with nine layers and a seismic mass of 8 g, it is possible to generate a power up to 1.3 µW at 140 Hz with an input acceleration of 1g. With better coupling between seismic mass and piezoelectret, and thus reduced damping, the power output of a single-layer system is increased to 5 µW at 700 Hz. Simulations indicate that for such improved setups with 10-layer stacks, utilizing seismic masses of 80 g, power levels of 0.1 to 1 mW can be expected below 100 Hz.

Energy harvesting from vibration with cross-linked polypropylene piezoelectrets

Journal Article Zhang, Xiaoqing ; Institute for Telecommunications Technology, Merckstrasse 25, 64283 Darmstadt ; Wu, Liming ; ... - AIP Advances

Piezoelectret films are prepared by modification of the microstructure of polypropylene foam sheets cross-linked by electronic irradiation (IXPP), followed by proper corona charging. Young’s modulus, relative permittivity, and electromechanical coupling coefficient of the fabricated films, determined by dielectric resonance spectra, are about 0.7 MPa, 1.6, and 0.08, respectively. Dynamic piezoelectric d{sub 33} coefficients up to 650 pC/N at 200 Hz are achieved. The figure of merit (FOM, d{sub 33} ⋅ g{sub 33}) for a more typical d{sub 33} value of 400 pC/N is about 11.2 GPa{sup −1}. Vibration-based energy harvesting with one-layer and two-layer stacks of these films is investigatedmore »« less

Vibration-based energy harvesting with piezoelectrets having high d{sub 31} activity

Journal Article Zhang, X. ; School of Physics Science and Engineering, Tongji University, Siping Road 1239, Shanghai 200092 ; Pondrom, P. ; ... - Applied Physics Letters

Sandwiched fluoroethylene propylene films with charged, parallel-tunnel voids between the layers, which exhibit high d{sub 31} piezoelectric activity, were designed. Stripes of such piezoelectrets were exposed to mechanical stress in length direction by a seismic mass excited to vibrations. Due to the piezoelectricity of the films, a current in a terminating resistor is generated. The harvested power across the resistor amounts to about 0.2 mW for a seismic mass of 2 g and an acceleration of 1 g. In comparison with other piezoelectret or with poly(vinylidene fluoride) harvesters, the generated power referred to equal acceleration and force, is significantly larger.

Fluoroethylenepropylene ferroelectret films with cross-tunnel structure for piezoelectric transducers and micro energy harvesters

Journal Article Zhang, Xiaoqing ; Institute for Telecommunications Technology, TU Darmstadt, Merckstrasse 25, 64283 Darmstadt ; Sessler, Gerhard M., E-mail: g.sessler@nt.tu-darmstadt.de ; ... - Journal of Applied Physics

Layered fluoroethylenepropylene (FEP) ferroelectret films with cross-tunnel structure were fabricated from sheets of FEP films by template-patterning followed by a fusion-bonding process and contact charging. The typical piezoelectric d{sub 33} coefficients, measured by a quasi-static method of samples not annealed, are in the range of 1000–3700 pC/N. The resonance behavior of the samples is analyzed by dielectric spectroscopy which also yields Young's modulus. Microphones built with such films exhibit a somewhat decreasing frequency response up to 1 kHz, an increase of the responses due to diffraction effects at higher frequencies, and eventually a peak probably due to a thickness resonancemore »« less

Design and fabrication of non silicon substrate based MEMS energy harvester for arbitrary surface applications

Journal Article Balpande, Suresh S., E-mail: balpandes@rknec.edu ; Pande, Rajesh S. - AIP Conference Proceedings

Internet of Things (IoT) uses MEMS sensor nodes and actuators to sense and control objects through Internet. IOT deploys millions of chemical battery driven sensors at different locations which are not reliable many times because of frequent requirement of charging & battery replacement in case of underground laying, placement at harsh environmental conditions, huge count and difference between demand (24 % per year) and availability (energy density growing rate 8% per year). Energy harvester fabricated on silicon wafers have been widely used in manufacturing MEMS structures. These devices require complex fabrication processes, costly chemicals & clean room.

A dual electromagnetic array with intrinsic frequency up-conversion for broadband vibrational energy harvesting

Journal Article Chen, Jingfan ; Wang, Ya - Applied Physics Letters

This letter proposes a dual electromagnetic array to transform low frequency rectilinear vibrations into electricity with frequency up-conversion. The free of mechanical contact harvester consists of a rectilinear oscillator (R _LO) and an array of two identical rotary oscillators (R _TO). The R _TO includes a rotor and a stator. The rotor has eight cubic magnets distributed centrosymmetrically, and the stator has eight coils. Under rectilinear vibrational excitations, the R _LO drives the rotor of the R _TO to rotate through magnetic torque acting on the rotors. A slight fluctuation of the rectilinear motion can lead to a great changemore »« less
