TL;DR: An innovative skin-over-liquid system made of a periodic array of highly compliant microbumps actuated through an electrode-free electrohydrodynamic (EHD) pressure is proposed, demonstrated to be highly repeatable and capable of swelling and deflating easily under a simple thermal stimulation driven by the pyroelectric effect, thus providing a challenging platform that can be actively controlled at the microscale.
Spiral formation at the microscale by μ-pyro-electrospinning
Laura Mecozzi,Oriella Gennari,Romina Rega,Simonetta Grilli,S. Bhowmick,Mariano Gioffrè,G. Coppola,Pietro Ferraro +7 more
TL;DR: This work shows that μ-pyro-electrospinning is able to control whipping instabilities in order to form spiralling fibres directly on a support with true microscale regularity, and shows that polymer concentration plays a key role in producing reliable and long spirals.

Biospeckle Decorrelation Quantifies the Performance of Alginate-Encapsulated Probiotic Bacteria
Biagio Mandracchia,Julie Palpacuer,Filomena Nazzaro,Vittorio Bianco,Romina Rega,Pietro Ferraro,Simonetta Grilli +6 more
TL;DR: It is shown that through biospeckle decorrelation it is possible to quantify the shelf-time of alginate-encapsulated probiotic bacteria and their survival rate under simulated gastrointestinal conditions.
Maskless Arrayed Nanofiber Mats by Bipolar Pyroelectrospinning
Romina Rega,Oriella Gennari,Laura Mecozzi,Vito Pagliarulo,Alessia Bramanti,Pietro Ferraro,Simonetta Grilli +6 more
TL;DR: The b-PES is free from expensive electrodes, nozzles, and masks because it makes use simply of the structured pyroelectric field produced by the PPLN crystal used as collector, and shows clearly the reliability of the technique in producing a wide variety of arrayed fiber mats that could find application in bioengineering or many other fields.

Investigation of pyroelectric fields generated by lithium niobate crystals through integrated microheaters
S. Bhowmick,Mario Iodice,Mariano Gioffrè,Giovanni Breglio,Andrea Irace,Michele Riccio,G. Romano,Simonetta Grilli,Pietro Ferraro,Laura Mecozzi,Sara Coppola,Oriella Gennari,Romina Rega,G. Coppola +13 more
TL;DR: In this article, the pyroelectric field generated by lithium niobate crystals through integrated microheater structures was investigated under ambient conditions using a metallic probe connected to an oscilloscope, and the current impulses were related to the air breakdown induced by the electric field arising between the −Z face of the crystal and the metallic tip.
