“…The aggregation of CNT does not easily maintain the nature of high aspect ratio and thus the polarization efficiency decreases . Moreover, we compared with other PVDF based piezoelectric materials (PVDF/PDMS, PVDF/CNT, PVDF-TrFE, PVDF/P-CNT, PVDF/IL, PVDF/PMMA, PVDF/BaTiO3/MWCNT, PVDF/BTO, PVDF/MWCNT and PVDF/TrFE) as shown in Figure g. Our PVDF/CNT scaffold exhibited high beta crystal content, good mechanical property, and competitive output capability.…”

With rapid consumption of fossil energy and its impact on the environment, the desire for clean energy is gradually increasing around the world, and piezoelectric polymers have received extensive attention owing to their capability to harvest discrete mechanical energy in the environment. However, the existing piezoelectric devices are mostly low-dimensional fibers or films, making it difficult to achieve a good balance between mechanical robustness and piezoelectric output. Herein, a polyvinylidene fluoride (PVDF)/multiwalled carbon nanotube (MWCNT) scaffold with a hierarchical porous structure and geometry was fabricated by chemical-foaming-assisted fused deposition modeling (FDM). Chemical foaming was triggered by the heat accompanied during FDM molding, where a microporous structure was formed inside the part without affecting the geometric design to realize strain accumulation in normal space. Moreover, the conductive MWCNT formed discontinuous and parallel morphology around the pores, which not only promotes the polling process and formation of electrets, but also avoids the electrical breakdown caused by the formation of the conductive network. Accordingly, the combined effect of hierarchical structure and incorporation of MWCNT leads to a balanced piezoelectric (open circuit voltage of 8.46 V and short circuit current of 157 nA) and mechanical performance (compressive modulus of 14.07 MPa). These excellent properties all demonstrate the potential capabilities of the developed piezoelectric nanogenerators in the field of self-powered nanosensors and portable devices.

“…Piezoelectric polymers are better candidates for piezoelectric energy harvesting applications because they are mechanically flexible, so they can withstand high loads. They also generate sufficient voltage from which sufficient output power can be obtained, they can withstand high electric field strength because they have higher dielectric strength, they have low production cost, and the processing of polymer family materials is easier compared to ceramic materials [31][32][33][34][35].…”

Monitoring of railroad wagons is important for logistical processes, but above all for safety. One of the key parameters to be monitored is the temperature of the axle box and the bearings in the bogie. The problem with monitoring these parameters is the harsh environment and lack of power supply. In our research, we present a power supply system for a WSN node monitoring the bogie parameters. Knowing the operating conditions, we built a power supply system using a piezoelectric energy harvester. The harvester consists of three piezoelectric elements placed on a double arm pendulum beam. The circuit was modeled in the Comsol Multiphysics environment and then built and tested in laboratory conditions. After confirming energy efficiency, the system was tested on a freight car bogie during an 8 h trip. At typical car vibration frequencies (4–10 Hz), the system is able to generate 73 uW. Combined with an energy buffer of 1000 mAh (3.7 V), it can power a WSN node (based on the nRF5340 chip) for 13 years of operation.

“…To overcome these limitations of sensors based on either smart pattern design or piezoelectric composites, intrinsically stretchable piezoelectric materials in the form of polymer blends with tailored macroscopically uniform properties can be developed. Polymer blends containing the polar β phase PVDF have been widely studied as piezoelectric films and nanofibers, such as PVDF/poly(methyl-methacrylate) (PMMA), − PVDF/poly(vinyl alcohol) (PVA), PVDF/thermoplastic polyurethane (TPU), and PVDF/photopolymers, and their piezoelectric properties and stretchability are compared in Table S1. In particular, for stretchable sensor materials, PVDF/acrylonitrile butadiene rubber (NBR) blend can be a potential candidate that possesses both stretchability and piezoelectricity.…”

Stretchable piezoelectric stress/strain sensing materials have attracted substantial research interest in the fields of wearable health monitoring, motion capturing, and soft robotics. These sensors require operation under dynamic loading conditions with high strain range, changing strain/loading rates, and varying pre-stretch states, which are challenging conditions for existing sensors to produce reliable measurements. To overcome these challenges, an intrinsically stretchable poly(vinylidene fluoride) (PVDF) sensor is developed through the polymer blending of PVDF and acrylonitrile butadiene rubber (NBR). Through precipitation printing and vulcanization, the resulting PVDF/NBR blends exhibit strong β phase PVDF and a blend morphology with submicron-level phase separation, but also strains up to 544%. Both the blend morphology and the mechanical properties indicate that this PVDF/NBR blend can be considered as a continuous elastomer phase above micron scale. After electric poling and adding electrodes, the PVDF/NBR blends have excellent piezoelectric properties to be used as both stretching mode strain sensors and compression mode stress/force sensors. The stretching mode sensors can measure strain up to 70% without strain rate and prestretch dependence, while the compression mode sensors have a loading-rate-independent linear voltage−stress relationship up to 4.8 MPa stress and a negligible pre-stretch dependence. Therefore, the PVDF/NBR sensors can provide accurate and reliable stress/ strain measurements when attached to soft structures, which paves the way for sensing and calibration of soft robots under dynamic loading conditions.
