Printable lightweight polymer-based energy harvesting systems: materials, proce...

Polymer-based flexible energy harvesting systems based on several physical phenomena such as piezo-, pyro-, thermo-, and triboelectric effects have become increasingly relevant for self-powered nano -generator devices to, as an example, replace batteries in remote or inaccessible places, or develop self -powered sensors. Tailored properties of the materials, combined with advanced manufacturing tech-nologies, w...

Influence of polymer matrix on the luminescence of phosphor based printable ele...

This work reports on the development of printable electroluminescent materials and devices based on different polymer matrixes. For this purpose, different contents of zinc sulfide co-doped with copper (ZnS:Cu) particles (20, 40 and 60% wt.) were incorporated into styrene-ethylene-butylene-styrene (SEBS) (UV resistance and stretchable), poly(vinylidene fluoride (PVDF) (thermal, chemical and UV stability and hig...

Electroactive poly(vinylidene fluoride) electrospun fiber mats coated with poly...

Electrospun membranes with an active response are playing an increasing role in tissue regeneration by improving the ability of the materials to mimic the cellular microenvironment during cell culture. In this context, this work reports on the development of poly(vinylidene fluoride) (PVDF) electrospun fibers coated with polyaniline (PANI) and with polypyrrole (PPy). Both PANI and PPy successfully coated the fi...

Reconfigurable 3D-printable magnets with improved maximum energy product

In conventional magnets, neodymium with added heavy rare-earths is used in order to induce high output and size reduction. But as deposits of heavy rare-earths such as dysprosium (Dy) and terbium (Tb) are disproportionately distributed, it is important to reduce the amount used due to supply issues and material costs. Additionally, the use of rare-earths in applications that only need modest magnetic properties...

Water-based graphene inks for all-printed temperature and deformation sensors

Graphene (G) has been combined with carboxymethyl cellulose (C) for the development of environmentally friendly inks for printed electronics applications. Water based ink formulations have been developed for screen printing with graphene content up to 90 wt.%. The printed patters show a good distribution of the graphene within the cellulose matrix, allowing a good screen-printed pattern definition with line thi...
