An interactive hybrid book integrating capacitive, piezoelectric, and piezoresi...
Gonçalves, Sérgio Abílio Pereira; Pereira, Nelson Miguel Macedo Silva; Costa, Carlos Miguel Silva; Branco, Pedro; Lanceros-Mendez, S.The arising of novel paradigms in human–computer interaction, including tangible user interfaces, shape-changing interfaces, or ubiquitous computing, is breaking down the boundary between physical and digital realms, leading to more natural and immersive forms of interaction. Advances in active and responsive smart materials allow to transform once inanimate objects, such as books, into actively responsive obje...
New generation of interactive platforms based on novel printed smart materials
Gonçalves, Sérgio Abílio PereiraThe last decade was marked by the computer-paradigm changing with other digital devices suddenly becoming available to the general public, such as tablets and smartphones. A shift in perspective from computer to materials as the centerpiece of digital interaction is leading to a diversification of interaction contexts, objects and applications, recurring to intuitive commands and dynamic content that can propor...
Optically transparent silk fibroin/silver nanowire composites for piezoresistiv...
Reizabal, Ander; Gonçalves, Sérgio Abílio Pereira; Pereira, Nelson; Costa, Carlos Miguel Silva; Pérez, Leyre; Vilas-Vilela, José L.; Lanceros-Méndez, S.This work focuses on the development of a novel generation of bio-based advanced multifunctional materials, able to replace the synthetic ones and thus contributing to sustaibanility. Silk Fibroin (SF), a protein obtained from Bombyx mori cocoons, has been selected due to its natural accessibility, physico-chemical properties and facile processability. In order to extend its functionality, SF was combined with ...
Optimized silk fibroin piezoresistive nanocomposites for pressure sensing appli...
Reizabal, A.; Gonçalves, Sérgio Abílio Pereira; Brito-Pereira, R.; Costa, P.; Costa, Carlos Miguel Silva; Pérez-Álvarez, L.; Vilas-Vilela, J. L.Environmental issues promote the development of sensors based on natural polymers which are becoming an area of increasing interest. Piezoresistive sensors based on silk fibroin with carbon nanotubes (CNTs) as fillers were produced by solvent-casting in order to tune their electrical conductivity and electromechanical responses. It is shown that the carbonaceous fillers are well dispersed in the polymer matrix ...
Recent progress on piezoelectric, pyroelectric, and magnetoelectric polymer-bas...
Costa, Pedro Filipe Ribeiro; Nunes-Pereira, João; Pereira, N.; Castro, N.; Gonçalves, Sérgio Abílio Pereira; Lanceros-Méndez, S.Energy harvesting from the environment based on electroactive polymers has been increasing in recent years. Ferroelectric polymers are used as mechanical-to-electrical energy transducers in a wide range of applications, scavenging the surrounding energy to power low-power devices. These energy-harvesting systems operate by taking advantage of the piezoelectric, pyroelectric, and magnetoelectric properties of th...
