Printed degradable piezoelectric microsystems: From ink formulation to device fabrication and characterization

As the world moves further and further into the semiconductor era, the amount of waste generated from electronics ("e-waste") is increasing rapidly and unsustainably. Of particular note, alternatives to lead-based piezoelectric materials must be establishe ...

Cartesian robot gripper

The purpose of this semester project is to move in 3D space the gripper to grab an object, move it and release it. To do so a cartesian 3D printer will be used to move the gripper. Some modifications needs to be done in order to install the gripper at the ...

Fabrication of zipping electrostatic actuators incorporating inkjet-printed layers

Herbert Shea, Samuel Rosset, Giulio Grasso

Zipping electrostatic actuators operate by bending flexible electrodes using electrostatic forces. This principle allows the use of a wide range of dielectric and conductive materials. Additive Manufacturing (AM) techniques can be used to fabricate these a ...

Inkjet Printing of Functional Polymer Composites for Chemiresistive Gas Sensors

Jürgen Brugger, Thomas Maeder, Mohammadmahdi Kiaee

Drop-on-Demand Inkjet printing can be used as an effective technique to deposit the sensing layer in chemiresistive gas sensors. In this type of gas sensors, a composite containing an insulating polymer mixed with a conductive filler is used for sensing an ...

Inkjet Printing of Viscous Monodisperse Microdroplets by Laser-Induced Flow Focusing

Demetri Psaltis, François Gallaire, Christophe Moser, Paul Delrot, Miguel Antonio Modestino

The on-demand generation of viscous microdroplets to print functional or biological materials remains challenging using conventional inkjet-printing methods, mainly due to aggregation and clogging issues. In an effort to overcome these limitations, we impl ...

Color changing effects with anisotropic halftone prints on metal

Roger Hersch, Petar Pjanic

We propose a color reproduction framework for creating specularly reflecting color images printed on a metallic substrate that change hue or chroma upon in-plane rotation by 90°. This framework is based on the anisotropic dot gain of line halftones when vi ...

On the Vulnerability of Finger Vein Recognition to Spoofing

Sébastien Marcel, Pedro Tomé

The vulnerability of finger vein recognition to spoofing is studied in this paper. A collection of spoofing finger vein images has been created from real finger vein samples. Finger vein images are printed using a commercial printer and then, presented at ...

Nanocomposites based on highly luminescent nanocrystals and semiconducting conjugated polymer for inkjet printing

Jürgen Brugger, Kristopher Pataky

In this work nanocomposites based on organic-capped semiconductor nanocrystals formed of a core of CdSe coated with a shell of ZnS (CdSe@ZnS), with different sizes, and a semiconducting conjugated polymer, namely poly[(9,9-dihexylfluoren-2,7-diyl)-alt-(2,5 ...
