(author), Margallo Balbas, E (author), Sarro, Pasqualina M (author)In this paper, we present an electrothermal biaxial MEMS actuator system, which provides x-A nd y-direction scanning for a fully integrated 3-D optical coherence tomography (OCT) scanner. An angular scanning range of 8° (corresponding to a 7-mm linear scanning range in both directions) is achieved, with an average power consumption of 150 mW....journal article 2018

(author), Irace, Andrea (author), Zhang, Kouchi (author), Sarro, Pasqualina M (author)The high aspect ratio and the porous nature of spatially oriented forest-like carbon nanotube (CNT) structures represent a unique opportunity to engineer a novel class of nanoscale assemblies. By combining CNTs and conformal coatings, a 3D lightweight scaffold with tailored behavior can be achieved. The effect of nanoscale coatings, aluminum...journal article 2018

(author), Sarro, Pasqualina M (author)A highly miniaturized, single-chip, large scanning range MOEMS scanner is demonstrated. This intrinsically-aligned, monolithically integrated device uses small angular displacement to provide a linear scanning range of 2000 μm in the lateral and 1000 μm in the vertical direction, at a working distance of 2 cm, with an average operating power...conference paper 2018

Pandraud, G. (author), Milosavljevic, S. (author), Sammak, A. (author), Cherchi, Matteo (author), Jovic, A. (author), Sarro, Pasqualina M (author)In this work, we present the results of integrated Ge detectors grown on a Si photonic platform for sensing applications. The detectors are fabricated on a passive photonic circuit for maximum coupling efficiency. Measurement results at 1300 nm wavelength show a responsivity of 0.2 A/W and very low dark current levels. For a voltage range...conference paper 2017

(author), Sarro, Pasqualina M (author)In this paper we present the characterization of the coefficient of thermal expansion (CTE) of in-situ doped polycrystalline SiC thin films, obtained by low pressure chemical vapor deposition (LPCVD). The material is characterized using V-beam actuators on which the temperature coefficient of resistance (TCR) and the in-plane displacement...journal article 2016
