PVDF based Piezoelectric (PZL) devices were fabricated to realize a very thin and simple bendable device to be integrated with the PMP layers. In this way the PMP / PZL structure, with the use of the copper foil, will be able to integrate easily and will be able to dissipate the heat more simply if…
We are proud to announce that collaborative work of the PULSE-COM team resulted in a European Patent submission. The patent EP21461595.7 entitled: “Photo-Piezoelectric Energy Generator of Electrical Energy from Light Energy” was filed in September 2021. The patent protects the topology of harvester (Figure 1), which uses PMP/PZL bilayer’s cyclic bending to convert light into…
In PULSE-COM project are investigated several piezoelectric elements to be integrated on the photomobile-polymer (PMP). The two main functions of the piezoelectric layer are: Sensing, Energy harvesting, Indeed, when the PMP bends due to light excitation, it is expected the mechanical deformation is converted into electricity by the mean of the direct piezoelectric effect. To…
By repeating the experiments made on first PMP with ZA4 PMP, we saw that some important PMP characteristics were changed, thus the embossing was no longer possible. So, another approach was tried. First, we tried to form a thick, ordered film of sub-micron spheres onto the membrane and we successfully performed this for a colloidal…
Piezo-semiconducting zinc oxide (ZnO) nanowires (NWs) are excellent candidates for the fabrication of energy harvesters, mechanical sensors, piezotronic and piezophototronic devices [1]. They are grown typically from thin seed layers. Low temperature fabrication methods are required for their integration on flexible substrates. Vacuum-free methods of deposition will eventually reduce their fabrication cost. In PULSE-COM, within…
CNR successfully prepared a Photo-Mobile Polymer (PMP) film self-vibrating while exposed to polarized light. The protocol of preparation can be observed in Fig.1 and in brief it involves the preparation of polymer coated glass slides that will be used as minireactors for the polymerization. The mix used (Figure 2A) is introduced in the cells by…
At the beginning of this month, a two-days remote school had been organised by the consortium on smart materials for opto-electronic applications. The aim was to bring to the attendees the concepts and basic working principles on Smart Materials Technologies from experts in the fields coming from both academy and industries. 16 lectures had been…
Another method for improving the PMP properties is the opal-inverse opal imprinting on PMP surface. The inverse opals [1] are ordered porous solids, a sort of photonic crystals [2] much cheaper and with large number of layers. The main characteristic of photonic crystals is the existence of the photonic band gap (PBG) which makes visible…
