“…Piezoelectric polymer based FPEHs are highly attractive due to their inherent flexibility, light weight and low temperature preparation of the active components. [141][142][143][144][145][146][147][148] Though the polymers exhibit relatively low piezoelectric coefficients as compared to that of piezoceramics, a suitable device structure enables high scavenged output in the case of polymer devices.

“…The active material was multilayered screen-printed P(VDF-TrFE). Their transducer was able to harvest 0.97 mW at 33 Hz under a large acceleration of 5.8 G. 9 More efficient transducer designs can increase the power output of piezoelectric harvesters. This entails ensuring that the piezoelectric material is effectively strained up to the maximum strain tolerated by the piezoelectric material.…”

“…PZT thin films on nickel substrates withstand strain levels up to 0.5% depending on the thickness and microstructure, 10 whereas PVDF films on Mylar are able to withstand strains up to 1%-2%. 9 The strain homogeneity plays a crucial role in the amount of power generated. The strain distribution in a simple cantilever beam decreases linearly from the clamped end toward the beam tip, where it is close to zero.…”

Piezoelectric energy harvesting from ambient vibrations offers an environmentally friendly approach to powering distributed sensors for the Internet of Things. This paper gives a direct comparison of Pb(Zr,Ti)O 3 (PZT)-and (K,Na)NbO 3 (KNN)-based harvesters using a compliant mechanism harvester design for resonant frequencies of 20, 40, and 70 Hz. At 70 Hz, the measured power densities for PZT-and KNNbased devices are 1139 and 31 μW/mm 3 , respectively, for unimorph structures on nickel foils of 25 and 50 μm in thickness. The power density ratios scale proportionally to the material energy harvesting figures of merit. Energy harvesting with the compliant mechanism design is twice as efficient when compared to harvesting with a simple cantilever beam.

We realize a vibration energy harvesting system based on fully printed piezoelectric transducers. The transducers have a butterfly‐like architecture based on two single optimized cantilevers with a resonance frequency tuned to 49.5 Hz and can be easily mounted to an industrial engine. By comparing single and multi‐stack configurations of the piezoelectric layers combined with full‐wave or voltage doubler rectifiers, the power transfer characteristics and impedance can be matched to the electrical requirements of the sensing circuitry. A single stack with 21 µm thickness results in the maximum power output of 14.4 µW at a vibration velocity of 11.5 mms‐1, typical for industrial engines. We use the system to power a wireless sensor node on a 1 kW rotary pump in normal operation. The system can harvest up to 138 mJ within 24 hours, sufficient for daily remote monitoring of the engine’s vibration spectrum and temperature state. Our system is thus suitable as low‐cost, ecofriendly power source for industrial IoT applications.This article is protected by copyright. All rights reserved.
