Flexible thermoelectric energy harvesting system based on polymer composites
Rodrigues-Marinho, T.; Correia, V.; Tubio, C. R.; Ares-Pernas, A.; Abad, M. J.; Lanceros-Mendez, S.; Costa, Pedro Filipe RibeiroFlexible and easy processing lightweight thermoelectric materials for energy harvesting applications have shown an increasing interest. Thermoplastic polyvinylidene fluoride (PVDF) and elastomer styrene-ethylene/butylene-styrene (SEBS) polymers reinforced with thermoelectric ceramics, including bismuth sulfide (Bi2S3), bismuth telluride (Bi2Te3) and antimony telluride (Sb2Te3), and electrically conductive carbo...
Graphene based printable conductive wax for low-power thermal actuation in micr...
Brito-Pereira, Ricardo; Ribeiro, Clarisse Marta Oliveira; Costa, Pedro Filipe Ribeiro; Correia, V.; Cardoso, Vanessa Fernandes; Lanceros-Mendez, S.Wax printing is one of the most widely used techniques to print hydrophobic barriers on hydrophilic microfluidic paper-based analytical devices (mu PADs) based on its simplicity, speed, and low cost, allowing large-scale production. Nonetheless, its function is just passive, without any action on fluids. Thus, this work proposes multifunctional hydrophobic composites based on conductive graphene nanoplatelets (...
Sustainable energy storage devices and device design for in the scope of intern...
Correia, V.; Costa, Carlos Miguel Silva; Lanceros-Mendez, S.The internet of things (IoT) is a parading increasingly implemented in current society. Mobility, interconnectivity, and communication of large amounts of data through sensors that need to be powered, require improved energy storage devices. In this chapter, the IoT concept is described together with the corresponding system components. Considering the need of sensors that must be powered, the most used energy ...
Smart and multifunctional materials based on electroactive poly(vinylidene fluo...
Costa, Carlos Miguel Silva; Cardoso, Vanessa Fernandes; Martins, Pedro Libânio Abreu; Correia, Daniela Maria Silva; Gonçalves, Renato FerreiraFrom scientific and technological points of view, poly(vinylidene fluoride), PVDF, is one of the most exciting polymers due to its overall physicochemical characteristics. This polymer can crystalize into five crystalline phases and can be processed in the form of films, fibers, membranes, and specific microstructures, being the physical properties controllable over a wide range through appropriate chemical mod...

Ribeiro, Sylvie Oliveira; Soares, M.; Hermenegildo, Bruno Filipe Costa; Correia, V.; Díez, A. García; Lanceros-Mendez, S.The authors regret that instead of “project PTDC/BTM-MAT/28237/2017” what should appear is “under project PTDC/BTM-MAT/28237/2017 (POCI-01-0145-FEDER-028237, funded also by the ERDF through the COMPETE2020 - Programa Operacional Competitividade e Internacionalização (POCI))”. The authors would like to apologise for any inconvenience caused.
Advances in printing and electronics: from engagement to commitment
Martins, Pedro Libânio Abreu; Pereira, N.; Lima, A. C.; Garcia, A.; Mendes-Filipe, C.; Polícia, R.; Correia, V.; Lanceros-Mendez, S.In recent years, printed electronics reached enormous popularity as a result of their huge potential to offer unique features that are not attainable through traditional fabrication, namely low-cost production, multifunctionality, stretchability, sustainability, and flexibility. Being expected a galloping increase in the use of printed technologies in the near future, due to the digitalization efforts associate...
Improving the performance of paper-based dipole antennas by electromagnetic flu...
Carvalho, R.; Brito-Pereira, R.; Pereira, N.; Lima, A. C.; Ribeiro, Clarisse Marta Oliveira; Correia, V.; Lanceros-Mendez, S.One of the essential issues in modern advanced materials science is to design and manufacture flexible devices, in particular in the framework of the Internet of Things (IoT), to improve integration into applications. An antenna is an essential component of wireless communication modules and, in addition to flexibility, compact dimensions, printability, low cost, and environ-mentally friendlier production strat...

Almeida, Teresa Isabel Marques; Correia, V.; Fernández Martín, Eduardo; García Díez, Ander; Ribeiro, Clarisse Marta Oliveira; Lanceros-Méndez, S.The biomedical area in the scope of tissue regeneration pursues the development of advanced materials that can target biomimetic approaches and, ideally, have an active role in the environment they are placed in. This active role can be related to or driven by morphological, mechanical, electrical, or magnetic stimuli, among others. This work reports on the development of active biomaterials based on poly(3-hyd...

Ribeiro, Sylvie Oliveira; Soares, M.; Hermenegildo, Bruno Filipe Costa; Correia, V.; García Díez, A.; Lanceros-Méndez, S.The present work reports on a new approach based on electroactive microenvironments to mitigate skeletal muscle cancer. For that, piezoelectric films based on poly(vinylidene fluoride) have been applied to evaluate the influence of mechano- and/or electrical stimuli on rhabdomyosarcoma (RMS) proliferation. Human embryonal rhabdomyosarcoma (RD) cells were cultured on PVDF pristine films with different surface ch...
