Abstract: A sensor has a sensor body with a first face and a second face opposite to one another, and a circuit arrangement supported by the sensor body that includes a first electrical circuit pattern on the first face, a second electrical circuit pattern on the second face, connection means, which electrically connect the first circuit pattern to the second circuit pattern and has at least one through hole that extends axially between the two faces of the sensor body. A plurality of terminals are electrically connected to the first circuit pattern and/or the second circuit pattern. The at least one through hole is preferably closed at the second face of the sensor body via a closing member (30) having pre-formed body with a closing portion having a diameter, greater than a diameter, of the opening of the through hole at the second face of the sensor body.

Abstract: A improved sol-gel process is described for the production of silica aerogels, in particular from plant raw materials, in particular from rice processing waste.

Abstract: A sol-gel process allowing preparation, on a substrate, of glassy films of silicon oxide or mixed oxides based on silicon oxide, of thickness above 1 micrometer, generally between 2 and 20 micrometers and characterized by absence of defects, that turn out to be particularly suitable as waveguides in flat optical devices.
